An EMD SDP40 is a 6-axle passenger diesel locomotive
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...

Besides horsepower
Horsepower
Horsepower is the name of several units of measurement of power.

The unit was widely adopted to measure the...

  • 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.
  • FXE 3227 appears to have been rebuilt from an SDP40, but the original locomotive number is unknown. The steam generator air intake was plated over during the rebuild, but it retained the full compartment and vertical rear steps.
  • MRL 290 was wrecked in 1988, and subsequently sold to MRL. It is listed in rosters and lettered as an SDP40-2XR. Its steam generator air intake was plated over during the rebuild, but it retained the full compartment and vertical rear 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:
