What do you mean by "traps" here?
SEPTA commuter rail has both low and high platforms, as by traditional
US railroad operations. In the train's vestibule, there is a trap
door on a hinge that is raised to allow steps to be used at low
platforms, and lowered to be used at high platforms.
NJ Transit trains have a similar device.
