Benefits of technology

[0010] Sliding guides, integral with the carrying structure of the train and cooperating with the frame supporting means, may be provided to facilitate insertion and extraction of the emergency generating unit in the compartment to make the unit easily inserted and removed.

Problems solved by technology

The windows of such trains are generally sealed and cannot be opened by travelers for safety reasons.
On the other hand, specifically high speed trains (especially those intended to travel alternatively on dedicated tracks and on normal railway tracks employed for traditional—i.e. not high speed—railway traffic) are frequently subject to breakage of the pantograph connecting the locomotive to the electrical power line with consequent power outage, that causes the train to stop and the on-board systems to stop working.
The power outage concerning air conditioning systems and the impossibility of opening the windows to ventilate the trains causes extreme discomfort and may even be dangerous for passengers.
Since the train may stop for a long time (in the order of 1-2 hours), ensuring sufficient autonomy for air conditioning systems for such a long time is not possible using electrical batteries considering that they draw so much power.
This solution (and others) would be excessively heavy.

Embodiment Construction

[0026]FIG. 1 schematically shows the front section of a train, generically indicated by reference numeral 1. Reference numeral 3 indicates the locomotive and references 7A and 7B indicate the first two carriages or cars forming the train. Both traction and the various systems aboard the carriages—specifically the air conditioning systems—are powered by the line 9 through the pantograph 11 of the locomotive. In the event of breakdown concerning the pantograph, the power to the utilities and to the systems in carriages 7A, 7B, . . . must be provided by emergency power units which equip each carriage 5, 7, . . . . FIG. 2 schematically shows seven train carriages numbered from 7A to 7F. Each carriage is equipped with an emergency generating unit, schematically indicated by references 13A-13F. As indicated in detail below, each emergency generating unit 13 is housed in a compartment underneath the floor of the respective carriage. The compartment is equipped with a flap for lateral acces...

Abstract

An emergency power generating unit (2), comprising a gas turbine (23) to supply a train on-board systems in the event of a failure of the main electrical power supply. Specifically the power generated by the turbine is used to run an electrical energy generator (29) for powering an air conditioning system (77).

Description

TECHNICAL FIELD [0001] The invention relates to an emergency power unit for generating electrical, mechanical or thermal power for a transportation vehicle and more specifically for a train. [0002] The invention also concerns a transportation vehicle and more particularly a train equipped with an emergency generating unit. BACKGROUND OF THE INVENTION [0003] Modern trains are equipped with technical systems which require continuous power for operation. Power is supplied by the electrical line along the railway track. Of all the technical systems installed aboard trains, air conditioning systems draw most power. These systems are used on all modern trains, specifically high speed trains. The windows of such trains are generally sealed and cannot be opened by travelers for safety reasons. On the other hand, specifically high speed trains (especially those intended to travel alternatively on dedicated tracks and on normal railway tracks employed for traditional—i.e. not high speed—railw...
