SP 5479
This loco was built in 3/1956 with EMD construction number 21304. It was built with boiler controls, but without a steam generator or water tank for reserve passenger service.

It was painted in standard for the time "black widow" colors and featured a full 5 light headlight arrangement on each end.
She was assigned number SP 3953 in the 1965 system renumbering.
She was one of the few SD9's not rebuilt as part of the GRIP program.
