Nope, you watch the music vid and you can tell it's not a diesel. It looks more likely to be compressed air powered. Could be wrong though. However, as to the pick up on the car, I've seen something similar to that before, but it's not for what you may think.
In situations where non electric trains share the same trackage as trams, sometimes you see this. (Especially on diesel locos) Basically, the pantograph or pickup doesn't do anything else beyond provide a contact for the signaling system. Meaning it just activates lights and such that prevent automobiles from crossing the line when the train is there.
That's also something you don't see often. The loco has it's own built in turntable. In the form of a plate that lowers, raising the loco off the ground and allowing the crew to turn it around.
