it's of a PCC streetcar in Kenosa, WI. They cammed up the streetcar so as to show the foot-pedal accelerator in action. There are views of what the operator sees as the car moves down the track, the foot pedal control, and an under-carriage shot of the trucks and the accelerator itself.
Of course, all of the streetcars here in New Orleans use a hand throttle, but this is still a neat-but-geeky video.
