A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive. This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel. Upon exiting the tunnel, the locomotives' full operating capabilities are quickly restored by enhancing their thermal recoveries.

The present invention provides a method that increases screen space of a computing device by using semi-transparent functional areas that overlap non-functional content areas on the screen. This method allows for relatively large functional targets on the screen—thus mitigating the usability problems associated with tiny buttons and other images—while also allowing the underlying content on the screen to be clearly visible. A main design feature of this invention is that two functional areas are never allowed to overlap. An overlap condition would cause user confusion as to which layer is active. Instead, the interface is designed to foreground functionality in all instances.

An oil-immersed and high-pressure tripping switch structure comprises an operational apparatus, an arc-extinguishing cylinder, and an oil-shortage automatic tripping safety device wherein a sensory device detecting a fault current will trip open to displace a spring rebound pivoting-point, permitting a main spring to simultaneously actuate the release of contact points and the rotation of an operational handle therewith so that the operational handle is rotated to recover its primary angle so as to indicate the tripped / off status of the switch, facilitating the judgment and operation of workers. In addition, via a buoyant tube combined with an oil-retaining tank, the buoyant tube in case of oil-shortage can generate a sufficient downward pressure to activate the release of a tripping device so as to ensure the safety of the present invention in operation. Furthermore, a complex arc-interruption mechanism is applied so that the arc-extinguishing cylinder can efficiently break higher fault current thereby.
