ABSTRACT:
A train car with mirror image electrical couplings having mirror image halves at each end for connecting train lines in each car to corresponding train lines in adjacent cars, regardless of the end-to-end orientation of the car, has selected pairs of train lines connected to corresponding pairs of switches for each end of the car for switching the halves of each selected pair of train lines between one or the other halves of the mirror image electrical couplings, depending on the orientation of the car.
