Description

Technical Field

[0001] This disclosure relates to the field of rail train safety technology, specifically to anti-climb systems, control methods for anti-climb systems, and trains. Background Technology

[0002] As urban rail transit passenger volume continues to increase, vehicle operating speeds are also gradually rising. While bringing convenience to people, potential hazards are also lurking in the surrounding area. For example, during vehicle operation, signal interruptions or other unexpected situations may lead to collisions, posing safety risks.

[0003] While further strengthening active safety protection measures for vehicles to reduce collision accidents, it is also crucial to improve the safety and reliability of vehicles during operation from the perspective of passive safety protection. Summary of the Invention

[0004] In view of the above problems, this disclosure provides an anti-creep system, a control method for the anti-creep system, and a train.

[0005] According to a first aspect of this disclosure, an anti-crawling system is provided, comprising:

[0006] An anti-climb device includes an anti-climb device body, an energy-absorbing body, and a gas generator. The energy-absorbing body is connected to the anti-climb device body and can be ejected relative to the anti-climb device body. The gas generator is connected to the anti-climb device body and is located at one end of the anti-climb device body opposite to the ejection direction of the energy-absorbing body. The gas generator includes a main gas generator and a redundant gas generator.

[0007] The controller includes a main control terminal and a redundant control terminal. The main control terminal is connected to the main gas generator of the anti-climb device and is used to send a first electrical pulse signal to the main gas generator when a control command is received. The redundant control terminal is connected to the redundant gas generator of the anti-climb device and is used to send a second electrical pulse signal to the redundant gas generator when a control command is received.

[0008] The main gas generator is used to generate a first gas based on the received first electrical pulse signal, so that the first gas pushes the energy absorber to pop out of the anti-climb device body to absorb energy.

[0009] The redundant gas generator is used to generate a second gas based on a received second electrical pulse signal when it is determined that the main gas generator has not generated the first gas, so that the second gas pushes the energy absorber out of the anti-climb device body to absorb energy.

[0010] According to embodiments of this disclosure, the main gas generator is configured with a main gas outlet;

[0011] The anti-climb system also includes:

[0012] Conductors, including main conductors and redundant conductors;

[0013] Among them, the main line, the main control terminal and the main gas generator form a main circuit for transmitting the first electrical pulse signal;

[0014] The redundant wire passes through the main gas outlet and forms a redundant circuit with the redundant control terminal and the redundant gas generator to transmit the second electrical pulse signal.

[0015] According to embodiments of this disclosure, the anti-climb system further includes:

[0016] A gas pressure regulating valve is disposed between the gas generator and the energy absorber, and is used to release the gas pressure when the pressure of the first gas and / or the second gas exceeds the preset pressure.

[0017] The second aspect of this disclosure provides a control method for an anti-climbing system. The anti-climbing system includes an anti-climbing device and a controller. The anti-climbing device includes an anti-climbing device body, an energy-absorbing body, and a gas generator. The gas generator includes a main gas generator and a redundant gas generator. The controller includes a main control terminal and a redundant control terminal.

[0018] The control methods for anti-climb systems include:

[0019] Upon confirming that the controller has received a control command, the main control terminal sends a first electrical pulse signal to the main gas generator.

[0020] When the preset time interval for the first electrical pulse signal is determined, the redundant control terminal sends a second electrical pulse signal to the redundant gas generator.

[0021] If the main gas generator does not generate the first gas based on the received first electrical pulse signal, the redundant gas generator generates the second gas based on the received second electrical pulse signal, so that the second gas pushes the energy absorber out of the anti-climb device body to absorb energy.

[0022] According to embodiments of this disclosure, the anti-climb system further includes wires, including redundant wires;

[0023] If the main gas generator fails to generate the first gas based on the received first electrical pulse signal, the redundant gas generator generates the second gas based on the received second electrical pulse signal. This second gas then propels the energy absorber out of the anti-climb device body to absorb energy, including:

[0024] If it is determined that the main gas generator does not generate the first gas based on the received first electrical pulse signal, the state of the redundant circuit is determined. The redundant circuit is used to characterize the circuit formed by the redundant wire through the main gas outlet, the redundant control terminal and the redundant gas generator. The state is used to characterize whether the redundant circuit is broken by the first gas.

[0025] If the state characterization of the redundant circuit is determined to be that the redundant circuit has not been interrupted by the first gas, based on the redundant circuit, the second electrical pulse signal triggers the redundant gas generator to explode, generating the second gas.

[0026] The second gas rushes out from the redundant gas outlet of the redundant gas generator, pushing the energy absorber out of the anti-climb device body to absorb energy.

[0027] According to embodiments of this disclosure, the control method for the anti-climb system further includes:

[0028] If it is determined that the first electrical pulse signal is transmitted from the main control terminal to the main gas generator, and the first electrical pulse signal does not trigger the explosion of the main gas generator, it is determined that the main gas generator does not generate the first gas based on the received first electrical pulse signal.

[0029] According to embodiments of this disclosure, the anti-climb system further includes wires, which include a main wire and redundant wires;

[0030] The control methods for anti-climb systems also include:

[0031] When it is determined that the first electrical pulse signal is transmitted from the main control terminal to the main gas generator, and the main line forms a main circuit with the main control terminal and the main gas generator, the first electrical pulse signal triggers the main gas generator to explode and generate the first gas.

[0032] After the first gas rushes out of the main gas outlet of the main gas generator, it breaks the redundant circuit and pushes the energy absorber out of the anti-climb device body to absorb energy. The redundant circuit is used to characterize the circuit formed by the redundant wire through the main gas outlet, the redundant control terminal and the redundant gas generator.

[0033] According to embodiments of this disclosure, the anti-climb system further includes a gas pressure regulating valve;

[0034] The control methods for anti-climb systems also include:

[0035] If it is determined that the pressure of the first gas and / or the second gas exceeds the preset pressure, a command is issued to open the gas pressure regulating valve in order to release the pressure.

[0036] According to embodiments of this disclosure, the control method for the anti-climb system further includes:

[0037] If it is determined that the explosion of the main gas generator produces the first gas and the explosion of the redundant gas generator produces the second gas, then the gas pressure exceeds the preset gas pressure.

[0038] A third aspect of this disclosure also provides a train that includes the aforementioned anti-climb system.

[0039] According to embodiments of this disclosure, by setting a main gas generator and redundant gas generators, as well as a main control terminal and redundant control terminals, it can be ensured that if the main gas generator malfunctions and fails to explode to generate the first gas, thus failing to push the energy absorber out of the anti-creep device to absorb energy, the redundant control terminal controls the redundant gas generator to explode and generate a second gas. The second gas then pushes the energy absorber out of the anti-creep device to absorb energy, ensuring passive safety protection. This redundancy effectively avoids unnecessary damage caused by a defective gas generator failing to explode and generate high-pressure gas, preventing the energy absorber from properly deploying and thus ensuring the front of the vehicle cannot absorb collision energy.

[0053] In the process of implementing this disclosure, it was discovered that the anti-creep device is an important device for the passive safety of trains. It can greatly ensure that the train absorbs the impact energy when an accidental collision occurs. Therefore, it is crucial to ensure the safe and reliable operation of the anti-creep device.

[0054] Embodiments of this disclosure provide an anti-climb system, a control method for the anti-climb system, and a train. An anti-climb system includes: an anti-climb device comprising an anti-climb device body, an energy-absorbing body, and a gas generator, wherein the energy-absorbing body is connected to the anti-climb device body and can be ejected relative to the anti-climb device body; the gas generator is connected to the anti-climb device body and located at one end of the anti-climb device body opposite to the ejection direction of the energy-absorbing body; the gas generator includes: a main gas generator and a redundant gas generator; and a controller including a main control terminal and a redundant control terminal, wherein the main control terminal is signal-connected to the main gas generator of the anti-climb device and is used to send a first electrical pulse signal to the main gas generator upon receiving a control command; the redundant control terminal is signal-connected to the redundant gas generator of the anti-climb device and is used to send a second electrical pulse signal to the redundant gas generator upon receiving a control command; wherein the main gas generator is used to generate a first gas based on the received first electrical pulse signal, so that the first gas pushes the energy-absorbing body to eject from the anti-climb device body to absorb energy; and the redundant gas generator is used to generate a second gas based on the received second electrical pulse signal when it is determined that the main gas generator has not generated the first gas, so that the second gas pushes the energy-absorbing body to eject from the anti-climb device body to absorb energy.

[0055] The following will be through Figures 1-2 The anti-crawling system of the disclosed embodiments is described in detail.

[0056] Figure 1 A schematic diagram of an anti-climbing system according to an embodiment of the present disclosure is shown.

[0057] like Figure 1 As shown, the anti-climb system of this embodiment includes an anti-climb device 1 and a controller ( Figure 1 (Not shown in the image). Specifically:

[0058] The anti-climb device 1 may include an anti-climb device body 11, an energy absorber 12, and a gas generator 13. The energy absorber 12 is connected to the anti-climb device body 11 and can be ejected relative to the anti-climb device body 11. The gas generator 13 is connected to the anti-climb device body 11 and is located at one end of the anti-climb device body 11 opposite to the ejection direction of the energy absorber 12. The gas generator 13 may include a main gas generator 131 and a redundant gas generator 132.

[0059] The controller includes a main control terminal and a redundant control terminal. The main control terminal is connected to the main gas generator 131 of the anti-climb device 1 and is used to send a first electrical pulse signal to the main gas generator 131 when a control command is received. The redundant control terminal is connected to the redundant gas generator 132 of the anti-climb device 1 and is used to send a second electrical pulse signal to the redundant gas generator 132 when a control command is received.

[0060] The main gas generator 131 is used to generate a first gas based on the received first electrical pulse signal, so that the first gas pushes the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0061] The redundant gas generator 132 is used to generate a second gas based on a received second electrical pulse signal when it is determined that the main gas generator 131 has not generated the first gas, so that the second gas pushes the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0062] According to embodiments of this disclosure, under normal vehicle operation, the energy absorber 12 can retract inside the front crossbeam of the vehicle body, unable to absorb impact energy. Energy absorption only occurs after the energy absorber 12 is ejected. For example, the controller can send an electrical pulse signal to the gas generator 13 via its output voltage. Upon receiving the electrical pulse signal, the gas generator 13 explodes, generating high-pressure gas. This high-pressure gas then propels the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0063] According to embodiments of this disclosure, when the vehicle's automatic identification system detects a collision, the automatic identification system can send a control command to the controller, but this is not limited thereto, and this disclosure does not specifically limit it.

[0064] According to embodiments of this disclosure, the main gas generator 131 and the redundant gas generator 132 can be two gas generators with completely identical performance.

[0065] According to embodiments of this disclosure, by setting a main gas generator and redundant gas generators, as well as a main control terminal and redundant control terminals, it can be ensured that if the main gas generator malfunctions and fails to explode to generate the first gas, thus failing to push the energy absorber out of the anti-creep device to absorb energy, the redundant control terminal controls the redundant gas generator to explode and generate a second gas. The second gas then pushes the energy absorber out of the anti-creep device to absorb energy, ensuring passive safety protection. This redundancy effectively avoids unnecessary damage caused by a defective gas generator failing to explode and generate high-pressure gas, preventing the energy absorber from properly deploying and thus ensuring the front of the vehicle cannot absorb collision energy.

[0066] Figure 2A schematic diagram of an anti-climbing system according to another embodiment of the present disclosure is shown.

[0067] like Figure 2 As shown, the anti-climbing system of this embodiment includes, in addition to, the following: Figure 1 In addition to the anti-climb device 1 shown, it may also include a controller 2 and a wire 3. Specifically:

[0068] The main gas generator 131 may be equipped with a main gas outlet A.

[0069] Controller 2 includes a main control terminal 21 and a redundant control terminal 22. Wire 3 may include a main wire 31 and a redundant wire 32.

[0070] The main control terminal 21 and the main gas generator 131 of the anti-climb device 1 form a main circuit through the main guide line 31 for signal transmission. The main control terminal 21 is used to send a first electrical pulse signal to the main gas generator 131 when a control command is received.

[0071] The redundant control terminal 22 and the redundant gas generator 132 of the anti-climb device 1 form a redundant circuit through the main gas outlet A via the redundant wire 32 for signal transmission. The redundant control terminal 22 is used to send a second electrical pulse signal to the redundant gas generator 132 when a control command is received.

[0072] According to an embodiment of this disclosure, when the main control terminal 21 receives a control command, it sends a first electrical pulse signal to the main gas generator 131. After receiving the first electrical pulse signal, the main gas generator 131 explodes to generate a first gas. The first gas rushes out from the main gas outlet A and breaks the redundant wire 32 wrapped around the main gas outlet A. The rushing out first gas then pushes the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0073] According to an embodiment of this disclosure, upon receiving a control command, the main control terminal 21 sends a first electrical pulse signal to the main gas generator 131. If the main gas generator 131 receives the first electrical pulse signal or fails to explode and generate the first gas due to not receiving the first electrical pulse signal, the redundant control terminal 22 sends a second electrical pulse signal to the redundant gas generator 132. Because the main gas generator 131 malfunctions and fails to explode and generate the first gas, the redundant wire 32 remains intact, and the redundant circuit is not broken by the first gas. Upon receiving the second electrical pulse signal, the redundant gas generator 132 explodes and generates the second gas. The second gas pushes the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0074] According to embodiments of this disclosure, the redundant gas generator 132 may also be configured with a redundant gas outlet. A second gas can escape from the redundant gas outlet, propelling the energy absorber 12 out of the anti-climb device body 11 to absorb energy.

[0075] According to embodiments of this disclosure, when the main gas generator normally explodes to produce the first gas, the redundant circuit is interrupted by the first gas because the redundant wire is broken, and the redundant gas generator will not explode to produce the second gas. This ensures that when the main gas generator normally produces the first gas, the redundant gas generator does not produce the second gas, avoiding the safety hazard caused by the gas pressure exceeding the design pressure of the anti-creep device. If the main gas generator does not normally explode to produce the first gas, the redundant gas generator will explode to produce the second gas because the redundant wire is not broken. This ensures that even when the main gas generator cannot normally produce the first gas, the redundant gas generator can still produce the second gas. The energy absorber can still eject from the anti-creep device body to absorb energy, achieving passive safety protection.

[0076] According to another embodiment of this disclosure, the anti-climb system includes, in addition to the above... Figure 1 The structure shown or the above Figure 2 In addition to the structure shown, it may also include:

[0077] A gas pressure regulating valve is disposed between the gas generator 13 and the energy absorber 12, and is used to release the gas pressure when it is determined that the gas pressure of the first gas and / or the second gas exceeds the preset gas pressure.

[0078] According to embodiments of this disclosure, the preset air pressure can be determined based on the design air pressure of the anti-climb device.

[0079] According to embodiments of this disclosure, when it is determined that the pressure of the first gas and / or the second gas exceeds a preset pressure, the gas pressure regulating valve opens rapidly, releases the pressure to the preset pressure, and then closes.

[0080] According to embodiments of this disclosure, if only the first gas or the second gas is generated, it can be determined that the pressure of the first gas or the second gas does not exceed a preset pressure. If both the first gas and the second gas are generated simultaneously, it can be determined that the pressure exceeds the preset pressure. This achieves a double safety measure: in addition to ensuring pressure safety by setting redundant wires through the main gas outlet, a gas pressure regulating valve is also used to ensure pressure safety.

[0081] According to embodiments of this disclosure, by setting a gas pressure regulating valve, the gas pressure can be released in a timely manner when the gas pressure exceeds the preset gas pressure, thus preventing safety hazards caused by excessive gas pressure.

[0082] Based on the anti-climbing system provided above, this disclosure also provides a control method for the anti-climbing system, which will be described below. Figure 3 The control method of the anti-crawling system according to the disclosed embodiments is described in detail.

[0083] Figure 3 A flowchart illustrating a control method for an anti-climbing system according to an embodiment of the present disclosure is shown.

[0084] like Figure 3 As shown, the control method of the anti-climbing system in this embodiment includes operations S310 to S330.

[0085] When operating S310, if it is determined that the controller has received a control command, the main control terminal sends a first electrical pulse signal to the main gas generator.

[0086] During operation S320, when a preset time interval is determined for the first electrical pulse signal to be emitted, the redundant control terminal sends a second electrical pulse signal to the redundant gas generator.

[0087] In operation S330, if it is determined that the main gas generator does not generate the first gas based on the received first electrical pulse signal, the redundant gas generator generates the second gas based on the received second electrical pulse signal, so that the second gas pushes the energy absorber out of the anti-climb device body to absorb energy.

[0088] According to embodiments of this disclosure, the anti-climb system may include: an anti-climb device and a controller. The anti-climb device may include: an anti-climb device body, an energy-absorbing body, and a gas generator. The gas generator may include: a main gas generator and redundant gas generators. The controller may include a main control terminal and redundant control terminals.

[0089] According to embodiments of this disclosure, the preset time interval can be in seconds, for example, 0.5s to 5s. This disclosure does not impose a specific limitation, as long as it ensures that the redundant gas generator explodes if the main gas generator does not explode, thus achieving passive safety protection. Alternatively, it can ensure that the redundant gas generator does not explode if the main gas generator explodes.

[0090] According to embodiments of this disclosure, when the vehicle's automatic identification system detects a collision, the automatic identification system sends a control command to the controller. Alternatively, the driver or a monitoring system may send a control command to the controller upon the occurrence of a collision, but this is not a limitation, and this disclosure does not impose specific restrictions thereon.

[0091] According to embodiments of this disclosure, after receiving a control command, the main controller outputs a control voltage and transmits a first electrical pulse signal to the main gas generator based on this control voltage. After a preset time interval, the redundant controller outputs a control voltage and transmits a second electrical pulse signal to the redundant gas generator based on this control voltage. Because the first electrical pulse signal is transmitted to the main gas generator first, the main gas generator does not explode to produce the first gas, while the redundant gas generator explodes to produce the second gas. The control voltage can be, for example, 12V, 24V, etc., and is not specifically limited here, as long as it conforms to the scope of electrical engineering.

[0092] According to embodiments of this disclosure, in the event that the main gas generator malfunctions and fails to explode to produce the first gas, the redundant gas generator can explode to produce the second gas. This second gas can propel the energy absorber out of the anti-climb device body to absorb energy, ensuring passive safety protection. By using preset time intervals and redundant control, safety issues caused by the energy absorber failing to eject properly due to the main gas generator not exploding can be effectively avoided.

[0093] According to embodiments of this disclosure, the anti-climb system may further include wires, which may include redundant wires.

[0094] According to embodiments of this disclosure, for example, Figure 3 The operation S330 shown, in which the main gas generator does not generate the first gas based on the received first electrical pulse signal, generates the second gas based on the received second electrical pulse signal, so that the second gas pushes the energy absorber out of the anti-climb device body to absorb energy, may include the following operations:

[0095] If it is determined that the main gas generator does not generate the first gas based on the received first electrical pulse signal, the state of the redundant circuit is determined. If the state of the redundant circuit indicates that it has not been interrupted by the first gas, based on the redundant circuit, a second electrical pulse signal triggers the redundant gas generator to explode, generating the second gas. The second gas, after exiting the redundant gas outlet of the redundant gas generator, pushes the energy absorber out of the anti-climb device body to absorb energy.

[0096] According to embodiments of this disclosure, a redundant circuit can be used to characterize the circuit formed by the redundant wire passing through the main gas outlet, the redundant control terminal, and the redundant gas generator, and the state can be used to characterize whether the redundant circuit is broken by the first gas.

[0097] According to embodiments of this disclosure, if the redundant circuit is not interrupted by the first gas, a second electrical pulse signal can trigger the redundant gas generator to explode, generating a second gas, based on the redundant circuit. Even if the main gas generator does not explode, the energy absorber can still be ejected from the anti-climb device body to absorb energy, achieving passive safety protection.

[0098] According to another embodiment of this disclosure, the control method for the anti-climb system includes, in addition to, the following: Figure 3 In addition to the operations S310 to S330 shown, the operation may also include: if it is determined that the first electrical pulse signal is transmitted from the main control terminal to the main gas generator and the first electrical pulse signal does not trigger the explosion of the main gas generator, the operation may also include: if it is determined that the main gas generator does not generate the first gas based on the received first electrical pulse signal.

[0099] According to embodiments of this disclosure, when there is a control voltage output at the main control terminal and the main circuit is intact, it can be determined that the first electrical pulse signal is transmitted from the main control terminal to the main gas generator.

[0100] According to embodiments of this disclosure, by determining that the main gas generator does not generate the first gas based on the received first electrical pulse signal, it can be determined that the redundant circuit has not been interrupted by the first gas. In turn, the redundant gas generator can generate the second gas based on the redundant circuit, ensuring that the energy absorber pops out of the anti-climb device body to absorb energy.

[0101] According to another embodiment of this disclosure, the anti-climb system may also include wires, which may include a main wire and redundant wires.

[0102] The control methods for anti-climb systems include, for example, Figure 3 In addition to operations S310 to S330, the operation may further include: when it is determined that the first electrical pulse signal is transmitted from the main control terminal to the main gas generator, and the main circuit is formed by the main line, the main control terminal, and the main gas generator, the first electrical pulse signal triggers the main gas generator to explode, generating the first gas. After the first gas rushes out of the main gas outlet of the main gas generator, it breaks the redundant circuit and pushes the energy absorber out of the anti-climb device body to absorb energy.

[0103] According to embodiments of this disclosure, a redundant loop is used to characterize the loop formed by the redundant wires passing through the main gas outlet, the redundant control terminal, and the redundant gas generator.

[0104] According to the embodiments of this disclosure, when the main gas generator produces the first gas, the redundant circuit is interrupted, and the redundant gas generator does not produce the second gas, thus avoiding the safety hazard caused by the gas pressure exceeding the design gas pressure of the anti-climb device after both the main gas generator and the redundant gas generator explode.

[0105] According to another embodiment of this disclosure, the anti-climb system may further include a gas pressure regulating valve.

[0106] The control methods for anti-climb systems include, for example, Figure 3In addition to operations S310 to S330, the operation may also include: when it is determined that the pressure of the first gas and / or the second gas exceeds the preset pressure, issuing a command to open the gas pressure regulating valve in order to release the pressure.

[0107] According to embodiments of this disclosure, when it is determined that the pressure of the first gas and / or the second gas exceeds a preset pressure, the gas pressure regulating valve is quickly opened by a command to open the gas pressure regulating valve, so that the pressure can be released to the preset pressure and then closed.

[0108] According to embodiments of this disclosure, the control method for the anti-climb system includes, in addition to, the following: Figure 3 In addition to operations S310 to S330 shown, the following operations may also be included:

[0109] If it is determined that the explosion of the main gas generator produces the first gas and the explosion of the redundant gas generator produces the second gas, then the gas pressure exceeds the preset gas pressure.

[0110] According to the embodiments of this disclosure, if it is determined that the main gas generator explodes to produce the first gas, the redundant gas generator does not explode, and the main gas generator is functioning normally, it can be determined that the gas pressure does not exceed the preset gas pressure.

[0111] According to the embodiments of this disclosure, if it is determined that the main gas generator has not exploded, the redundant gas generator explodes to produce a second gas, and the redundant gas generator is functioning normally, it can be determined that the gas pressure has not exceeded the preset gas pressure.

[0112] According to embodiments of this disclosure, by controlling the opening of the gas pressure regulating valve, the gas pressure can be released in a timely manner when the gas pressure exceeds the preset gas pressure, thus preventing safety hazards caused by excessive gas pressure.

[0113] This disclosure also provides a train that may include the anti-climb system described above.

[0114] According to embodiments of this disclosure, the train may include, but is not limited to, urban rail vehicles, intercity EMUs, modern trams, railway passenger cars, and railway freight cars.

[0115] According to the embodiments of this disclosure, the provided anti-climb system has a simple structure, high reliability, strong security, and is easy to implement, thus ensuring the passive safety of the train.

[0116] According to embodiments of this disclosure, the anti-climb device of the anti-climb system can be installed at the front of the train body. The front of the train body can be the end of the train that is in the same direction as the train's running direction. The controller can be installed in the driver's cab or any place that is easy to control. This disclosure does not make any specific limitations.

[0117] According to embodiments of this disclosure, after a train collision, the controller can cause the main gas generator to explode, producing a first gas, while the redundant gas generator does not explode, thus not producing a second gas. The first gas is used to propel the energy-absorbing body of the anti-creep device to absorb energy. Alternatively, if the main gas generator does not explode and does not produce the first gas, the redundant gas generator explodes to produce the second gas, which is then used to propel the energy-absorbing body of the anti-creep device to absorb energy. This achieves passive safety protection for the train.
