 Footboards are fitted under the outside of each door for boarding and alighting to/from low platforms; when boarding/alighting passengers to/from high platforms, these are covered by metal aprons (gap fillers).The end bulkheads of each car (except for the head end of the driving trailer, which is occupied by the engineer's cab) incorporate swing-down transfer platforms which allow passengers to walk between cars; these also damp the cars' pitching motion when the train is moving.The cars are long and wide.
