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 commuter rail system is operated by the Massachusetts Bay Commuter Railroad Company (MBCR).
Background
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]
The locomotives are scheduled to begin arriving in 2013 with a pilot locomotive expected to be delivered in June of that year.[7][8][1]
On July 27, 2011, the MBTA released images of a new paint scheme which will be applied to the authority's HSP46 fleet.[9] It was chosen by the general public in an online survey.[9]
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).[10]
On April 10, 2013, the MBTA Board approved the purchase of the remaining 13 option locomotives, bringing the current order total to 40 units (2000-2039).[11]
On October 24, 2013, the first pilot unit, #2001, was delivered to the MBTA's Boston Engine Terminal 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, PA and #2002 is at the TTA Test Facility in Pueblo, CO. Only the 2001 was given the MBTA paint scheme; the other two test units are unpainted.
