I think you have it right Herc. The slug does not have batteries or a generator, just traction motors. They are usually filled with cement to add weight to compensate for the weight removed when the Diesel engine and generator were removed. I think they are usually cut down to allow better visibility from the cab of the mother unit. I don't know what NS did to add weight to the slugs. I also don't know why they did not cut them down or eliminate the cabs on them. Is there a situation where they might want to have the cab intact and usable to control the mother from the slug?
