Can anyone help tell me what this locomotive is? All I know about it for sure is that it is a GE. Located at the Tennessee Central Ry museum in Nashville.

Shows up as a U36B and from the Trucks and Brake Piping I would have to say old SCL vintage one.
Seconded, U36B. The Blomberg trucks are a dead giveaway.
‘‘Third-ed’’
Seaboard Coast Line
GE U36B # 1822
Then to: SBD 1822 & CSX renumbered 5772
Built September 1971. Serial 38044
With the full sized flared radiators, 8 access doors, and those trucks there is only one thing it can be. U36B all the way. Interesting paint scheme though.
It is indeed a filthy stinking U-Boat. Thank goodness its in a museum where it belongs and not out on the mainline. Nice paint job though.
