EMD SDP40
Encyclopedia
An EMD SDP40 is a 6-axle passenger diesel locomotive
built by General Motors Electro-Motive Division between June 1966 and May 1970. Although few were produced, they enjoyed long service lives.
, the SDP40 is essentially a high-horsepower freight locomotive with additional equipment for passenger train service.
In 1966, EMD updated their locomotive catalog with entirely new models, all powered by the new 645
diesel. These included six-axle models SD38
, SD40
and SD45
, in addition to the SDP40. All shared standardized components, including the frame, cab, generator, trucks, traction motors, and air brakes. The primary difference was the power output: SD38 = 2000 hp from a non-turbocharged V16
, SD40 = 3000 hp from a turbocharged V16
, and SD45 = 3600 hp from a turbocharged V20
.
The SD40
and SDP40 were so similar that EMD published common operator's and service manuals to cover both.
Besides horsepower
, the primary characteristic of a passenger locomotive at the time was the ability to provide steam
to the passenger cars, for heating, cooking, and sometimes cooling. Secondary characteristics could include a higher gear ratio for faster running, addition of the graduated-release feature to the air brakes, type F tight-lock couplers
to keep equipment together in the event of a derailment, or extra signals and communication equipment. Of these, the steam generator was the largest, and had the greatest impact on the locomotive's appearance. To fit a steam generator
to the freight-only SD40
, the designers had to move all the machinery forward about two feet on the frame, add a compartment behind the radiators for the boiler, and divide the fuel tank into fuel and water sections.

Visually, the SDP40 is a hood unit
distinguished only by the shape of its rear end behind the radiators, with its flat end having no number boards, shuttered boiler air intake on each side, extra exhaust stacks over the boiler, cantilevered walkway around the flat end, and very steep rear steps. EMD applied this same end to the passenger SDP35
, SDP45
, and GP40P locomotives, as well as the freight DD35

and SD40T-2

Amtrak
's SDP40F
locomotive, although sharing several mechanical specifications, is visually a much different locomotive. Seven years separate their introductions, and the SDP40F was actually based on the SD40-2
. It had a full-width carbody, similar to the FP45
. It was also six feet longer than the SDP40.
, the United States
and Mexico
during the 1960s were limited to 111 units. In most cases, the purchaser intended to save costs by replacing older, less powerful locomotives.
The Great Northern Railway purchased the first six SDP40s in 1966, to replace older F-units
on the Western Star and smaller regional trains. Options included Vapor OK-4740 steam generators
, water-transfer capability between units, 59:18 gearing for a top speed of 83 mph, and Type-F couplers. These were followed in 1967 by eight more powerful SDP45
locomotives ordered for the Empire Builder
. After the startup of Amtrak
in 1971, Great Northern Railway successor Burlington Northern Railroad
converted all fourteen SDP passenger locomotives to freight service.
One SDP40, former Great Northern Railway 323, was temporarily renumbered 1976 and painted in red, white and blue for the United States Bicentennial
in 1976.
NdeM
's 14 were ordered in two groups: Ten in 1968 and four in 1970. In 1998, the government of Mexico
privatized the NdeM
, and the locomotives were split between two successor companies. Eight went to TFM, which was later purchased KCS and became KCSM. These eight have roamed freely in the United States
. The other six went to Ferromex
.
6399 was the lead unit of train 23 when it ran head-on into train 182 at Maiden Rock, WI
. 6399 was repaired and returned to service, as were the four units of the other train. The three trailing GP40
units were destroyed.
A consideration when rebuilding an SDP40 is that the rear corner steps do not comply with current Federal Regulations. The bottom step must be further out than the upper steps to provide a place to stand. Since the steam generator compartment extends to the end of the frame, it must be removed to install compliant switching steps. FXE 3212 and GCFX 3093 are examples. See:
The KCS pair rebuilt into SD22ECOs
took a different approach: The bottom steps of the rear ladders were moved out to meet the requirement.

Locomotive
A locomotive is a railway vehicle that provides the motive power for a train. The word originates from the Latin loco – "from a place", ablative of locus, "place" + Medieval Latin motivus, "causing motion", and is a shortened form of the term locomotive engine, first used in the early 19th...

The steam generator air intake was plated over during the rebuild. - FXE 3212 was rebuilt from an SDP40, but the original locomotive number is unknown. This rebuild resulted in removal of most of the steam generator compartment and installation of rear switching steps.

A consideration when rebuilding an SDP40 is that the rear corner steps do not comply with current Federal Regulations. The bottom step must be further out than the upper steps to provide a place to stand. Since the steam generator compartment extends to the end of the frame, it must be removed to install compliant switching steps. FXE 3212 and GCFX 3093 are examples. See:
- 49 CFR 231.29 Road locomotives with corner stairways
- 49 CFR 231.30 Locomotives used in switching service
