That is a 'Monster' - it is longer than normal and has a
'ventilated' rear power unit. Looks like the repair shop
took a unit that smashed up the cab but had a good generator

It's probably the standard issue 4400 hp unit, or prthaps the 6044
convertable variant, fairly common.

"The AC4400 (or C44AC) was GE's initial entrant into the AC-traction market,
and has proven extremely successful. Debuting in 1995, it has evolved into
several different versions over time, adding power-management and emissions
features to increase its flexibility and be more environmentally friendly
and effecient"
