Definitions

• This invention relates to a detrainment device for a rail vehicle comprising an emergency exit door integrated into a front of the rail vehicle and a movable ramp for bridging a coupler of the rail vehicle, wherein the ramp being associated with the emergency exit door and being movable from a storage position into an operational position.
• Rail vehicles like commuter trains are often operated at least partly in tunnel systems. If e.g. a commuter train has a failure and can not be moved any more, the rail vehicle needs to be detrained, or in emergency cases even to be evacuated. Since there is not at all points of existing tunnels a possibility to comfortably detrain the rail vehicle at its side, some railway operators also demand the feature to detrain the rail vehicle at its front .
• DE 41 08 575 C2 discloses an emergency exit door for rail vehicles which is arranged in the end wall of a railway carriage.
• the door consists of two parts wherein a hollow primary part contains a secondary part .
• the primary part is pivotably connected with a horizontal axis of rotation to the chassis of the railway carriage.
• the door can be lowered and the secondary part can be extracted from the hollow primary part, such that the two parts of the door form a ramp which touches the ground for enabling passengers to leave the railway carriage.
• a pneumatic cylinder is placed on one side of the door for ease of closing and a damper is set opposite so that the door can be lowered by itself after an accident.
• a secondary damper is situated inside of the hollow primary part allowing the ramp to be extracted with ease.
• This known emergency exit door has a complex structure and requires much space. Moreover, it considerably limits the view of the driver if it is arranged in the end wall of a driver's cab.
• Another solution for enabling passengers to leave a railway vehicle in case of emergency consists of windows which are provided with pull out rubber sealings. If the railway vehicle has a failure or in a case of emergency the rubber sealing of the respective window can be pulled out to enable passengers to take the window out off the window frame and to leave the vehicle through the window opening. ⁇ However, if the window, does not reach near to the floor of the railway vehicle it is difficult for passengers, particularly for elderly persons to get out off the vehicle through the window opening. Moreover, these pull-out rubber sealings are single use solutions, thus an easy closing of the windows is not possible.

Since the ladder 21 attached to the ramp 16 will not be needed for a train-to-train detrainment and may hamper passengers when they walk over the ramp 16, the ladder 21 will be removed from the ramp 16. In order to ensure a quick separation the ladder 21 is pivotably connected to the ramp 16 by quick release and fastening means 20. As indicated by the arrow in Fig. 3 the detached ladder 21 may be placed in the driver's area, e.g. behind the driver's seat 25.
