Detrainment device

A detrainment device is equipment on a rail vehicle that provides an evacuation route for the passengers.

A detrainment device is moved from a stored location into an operational position, usually above the coupler at the end of a passenger car.

A detrainment device may consist of a manually placed, hinged, foldable or telescopic ladder or ramp.

In other cases, evacuation may be via the vehicle passenger side doors to a trackside walkway in a tunnel, without the use of a detrainment device.

Examples of the main types of detrainment device currently in service include: User trials on prototype equipment in controlled conditions have indicated that a wide detrainment ramp will allow the evacuation of 2500 passengers in 28 minutes[10] if the ramp, its handrails and the cab and saloon throughways are correctly specified.
