Abstract
A ramp car for loading and unloading vehicles comprises first and second ramps mounted respectively to first and second wheel sets. The first and second ramps extend toward each other in a lowered loading position for providing access for vehicles to a train in both directions. The first and second ramps are locked to each other in a raised travel position. The ramp car also includes a displacement structure having guide mechanism associated with the first and second ramps for guiding the raising and lowering of the ramps. The ramp car is provided with a controller device for selectively controlling the operation of the ramp car. The controller device may be an integral part of the ramp car or may be selectively plugged into a port on either ramp of the car.
