@sercazaserca: The slug unit doesn't have exhaust pipes, fans, or radiators because it does not have its own prime mover. It obtains is current from the lead unit (sometimes called the "mother") for the traction motors by way of a m.u. connection. Thus, the slug cannot operate by itself.
Nice video, I have ridden with Roy on that run from Corning to NS yard but any more I have to get off at the mill because NS don't want any non RR personal on their property
The engines are running in what's called a cow/calf configuration. The slug or calf only has traction motors. The electrical power comes from the primemovers of the mother units, in this case GP10s #572 and #575. This boosts the overall tractive effort of the locomotive consist.
Yes it is called a MU cable connection. There are electrical cables called MU hooked up to all of the locomotives with cars not in between. When the engineer puts the front locomotive he his in to a notch (idle,1,8,etc) it sends a single to the other locos and they also go into that notch (power setting. There aren't exhaust stacks on slugs and the radiators are on the top I believe.
