There are five MPXpress models: MP36PH-3S, MP36PH-3C, MP40PH-3C, MP32PH-Q, and MP54AC. MPXpress locomotives were built with a high percentage of re-manufactured parts including diesel engines, major electrical components, trucks, and frames.

The MP54AC (also known as MP40PHTC-T4AC) is the latest locomotive in the MPXpress family and the only model available for sale in the US. It is designed to both meet the EPA's stringent Tier 4 emissions standard and offer higher performance than the MP40PH-3C.

The MP54AC (or MP40PH-T4AC) is MPI's Tier IV-compliant passenger locomotive offering. It uses two Cummins QSK60 diesel engines that produce a combined 5400 horsepower, but can operate on one engine if desired.

Powered by a 4000hp 16-cylinder EMD 710G3B-EFI-T2 and equipped with a 1000hp Caterpillar C27-ACERT HEP package, the MP40PH-3C's are the first locomotives ordered by GO able to supply power to a 12-car train by themselves. They are also faster, being geared for a …

Nov 26, 2016 · The MP40PH-3C was powered by a 16-cylinder 4000 horsepower EMD 710G3B-EFI-T2 engine with an additional 1000 horsepower Caterpillar C27-ACERT generator to provide head end power (HEP0). This made the model the first GO locomotives to be able to supply power to a 12 car train all by themselves.

There have been three major variations built of the MPXpress: The MP36PH-3S, the MP36PH-3C and the MP40PH-3C. The MP36PH-3S is the first version built, and has only been built for Chicago’s Metra. It is powered by a 3600 horsepower 16V-645F3B motor.

The MP40PH-3C is the third MPXpress Locomotive to be introduced. This unit is rated at 4,000 hp and primarily uses a 16-710G3B prime mover and a CAT C27 engine for HEP. EM2000 microprocessors are used vs. Wabtec Q-tron for MP36's.

The first MP54AC was created by converting a GO Transit MP40PH-3C accordingly. Only eleven examples of the MP32PH-Q were built for SunRail in the Orlando, Florida area. Most of these had been converted from former MARC (Maryland Area Rail Commuter) GP40WH-2s.
