Correct me if I’m wrong but its my understanding that a slug does not
generate power on its own. It is powered from the lead loco. The effect is
greater traction and power but less generation. They are seen a lot in
switching yards but not as much on long hauls.

That’s correct. A slug is an engine that’s had the cab and motors removed,
and often the fuel tanks as well. Sometines tha tank is retained and filled
with ballist. This was common with older engines such as a GP9 or GP15.
Either way, extra wieght is added to offset the missing structure and
engines. The (electric)motorized trucks are retained, and are slaved off of
another engine, that it’s permanently or simi permanantly coupled to. The
whole idea is to double the traction for slow heavy loads.
These are used in larger yards, often to pull loads over a hump.

A similar configuration is a “cow and calf”. In this case bothe engines
retain thier deisel motors and control systems, however one of the engines is
cabless. http://espee.railfan.net/sptr06.html
