Ex Southern Pacific SD40T-2 loco 8335. This unit was purchased for spares. 8335 was built in 1979, with the T signifying that it is a Tunnel motor with a modified radiator intake to allow 'cool' running through the Sierra Nevada tunnels. And the "M" with a lighting rod through it meant that it was a master unit for radio controlled helpers, used in the Tehachapi mountains.
