Career

The MPI HSP46 is a four-axle AC-traction diesel-electric locomotive for commuter trains, designed and assembled by MotivePower, Inc.[5] It meets EPA Tier 3 emissions standards. The launch customer is the Massachusetts Bay Transportation Authority (MBTA), whose first unit entered revenue service in April 2014.

History[edit]

The MBTA Board of Directors voted, on July 14, 2010, to approve the purchase of 20 new HSP46 locomotives from MotivePower, Inc. These are powered by GE GEVO-12 diesel engines from GE Transportation Systems,[1] equipped with a static inverter for head end power, and capable of meeting the stringent new Tier 3 emissions regulations. AC traction systems, prime movers, head end power equipment, and computer systems are supplied by GE, while MPI supplies the brake systems, air systems, and cooling systems.[6]

On July 27, 2011, the MBTA released images of a new paint scheme which will be applied to the authority's HSP46 fleet.[7] It was chosen by the general public in an online survey.[7]

On July 11, 2012, the MBTA Board voted to approve the first option for 7 locomotives, bringing the order total to 27 units (2000-2026).[8] On April 10, 2013, the Board approved the purchase of the remaining 13 option locomotives, bringing the current order total to 40 units (2000-2039).[9]

On October 24, 2013, the first pilot unit, #2001, was delivered to the MBTA Commuter Rail Maintenance Facility to begin testing and training. Two other pilot units have also been released from Motive Power Industries. #2000 is at GE's Test Facility in Erie, Pennsylvania and #2002 is at the TTC test facility in Pueblo, Colorado. Only #2001 was given the MBTA paint scheme; the other two test units are unpainted.

On April 16, 2014, #2001 entered revenue service, with its first round trip taking place on the Haverhill Line.[10]
