Safety is key
at peak times, when a train is full, it carries hundreds of passengers. Therefore, well-designed and manufactured detrainment systems are crucial to facilitating efficient evacuation from the front of the train.
Detrainment systems vary from train to train and can include a hinged, foldable or telescopic ladder or ramp; furthermore, there are several door manufacturing options, such as hinge upwards, plug and slide to the side of the front cab or open outwards. The deployment of the detrainment doors and systems is manual, so they are not affected by the loss of power to the train, in an emergency.
