SP SD40M-2 8691 Joins the Fleet
The SDP45 was the passenger adaptation of EMD's 20-cylinder, 3,600 horsepower SD45. 52 of these locomotives were built between 1967 and 1970. Distinguished from the freight SD45 by a longer frame, bigger fuel tank, and a distinctive square end to the long-hood behind the flaired radiators for steam generator equipment, the SDP45 is easy to spot. Only 18 SDP45 (10 Southern Pacific and 8 Great Northern) locomotives were built to serve as passenger locomotives. The Erie Lackawana purchased 34 of these locomotives with concrete ballast in the rear section instead of steam generator equipment to utilize the larger fuel tanks to reduce the need for fueling events en-route.
Of the 133 SP SD40M-2s numbered 8574-8706, the 8691 was one of the few rebuilt from an SDP45. The SP 8691 was built as EL 3654 in June of 1970. I was actively railfanning the SP when the SD40M-2s were delivered as new, so I could not pass up the opportunity to purchase one. And a beautiful model it is!
