EMD Design Dept. artwork proposal for NW2 switcher #55This roster encompasses the diesel locomotives owned or ordered by the Pere Marquette from the time of the merger that created it in 1900 until its merger into the Chesapeake & Ohio in 1947. This roster does not include locomotives ordered by the C&O for use on ex-PM lines.

It is interesting to note that while the PM purchased a large number of its steam locomotives from ALCo, it did not purchase a single ALCo diesel. Instead, the PM bought locomotives produced by a division of its largest single customer, General Motors. Had EMD offered a switcher in the 70-ton weight range, it is likely that switchers #20-22 would not have been purchased from GE.

Data for this roster were culled from PM equipment diagrams and Pere Marquette Power by Art Million and Tom Dixon. For more detailed information on the locomotives of the Pere Marquette, refer to Pere Marquette Power.
