MPI HSP46
Encyclopedia
The MPI HSP46 will be a four-axle AC-traction diesel-electric locomotive for commuter trains, currently being designed by MotivePower, Inc
. It will meet EPA Tier 3 emissions standards. The launch customer will be the Massachusetts Bay Transportation Authority
(MBTA), whose commuter rail system is operated by the Massachusetts Bay Commuter Railroad Company (MBCR).
, equipped with a static inverter
for head end power
, and capable of meeting the stringent new Tier 3 emissions regulations. AC
traction systems, head end power equipment, and computer systems will be supplied by GE, while MPI will be supplying the brake systems, air systems
, and cooling systems.
The locomotives are scheduled to begin arriving in 2013.
On July 27, 2011, the MBTA released images of a new paint scheme which will be applied to the authority's HSP46 fleet. It was chosen by the general public in an online survey.
