Notes

Sun Rail's MP32PH-Q locomotives were built by Wabtec subsidiary, Motive Power Industries, in Boise, ID. The locos ride on a pair of B-B trucks and are powered by a 645-prime mover rated at 3000 hp. The MP32s also feature a streamlined MPXpress-cab, which totally hides the the fact that the units had been originally built as GP40 freight engines and had later served MARC as GP40-CWH2 commuter power. The 645 power-plants were totally rebuilt or replaced, and new electrical / electronics installed throughout the units.

Thanks to the following people for additions / corrections: Bruce Mercer (via LocoNotes) and Michael Richmond.
