MP32PH-Q
The MPI MP32PH-Q is a diesel-electric passenger locomotive rebuilt by MotivePower for SunRail, using a rebuilt EMD 16-645E3C prime mover producing 3,200 horsepower. The MP32PH-Q retains a hood unit layout from its GP40WH-2 origins but features a new four-window MPXpress cab and upgraded electronics.[1]

What it is
The MP32PH-Q is a diesel-electric passenger locomotive in the MPI MPXpress line built by MotivePower. The MP32PH-Q was built from 2013 to 2017 for commuter rail service on SunRail. SunRail is the only operator of the MP32PH-Q. The MPXpress line is a family of commuter rail locomotives that incorporated a high percentage of re-manufactured parts when new.[1]
How it works
The MP32PH-Q is rebuilt and refurbished from locomotives that previously operated on MARC as GP40WH-2 units. The MP32PH-Q uses the EMD 16-645E3C as its prime mover, a rebuilt engine rated at 3,200 horsepower. Electronics in the MP32PH-Q were upgraded using systems similar to those used on other MPXpress locomotives.[1]
Where it fits in the process flow
SunRail, the sole operator of the model, uses the MP32PH-Q in its commuter rail passenger service. The MP32PH-Q was built specifically for the SunRail system.[1]
Applications
The MP32PH-Q is applied to commuter rail passenger service, with SunRail as its only operator. The MP32PH-Q was built for the SunRail system between 2013 and 2017.[1]
