The MBTA unveiled its first new locomotive in 23 years during a ceremony at South Station this morning.
Lieutenant Governor Timothy Murray joined officials from the MBTA aboard the new diesel-electric locomotive on its inaugural ride from Worcester to Boston.
Officials said the locomotive is one of two new trains purchased from the Utah Transit Authority.
Murray told reporters at South Station the Patrick administration is committed to improving commuter rail service for commuters.
The MBTA's commuter rail service has been under attack after repeated delays and breakdowns in commuter rail service during the harsh winter.
Officials said new technology makes the engines more fuel-efficient and prevents unnecessary idling and the new locomotives will reduce air pollutant levels by 20 tons per engine annually.
A press release stated that each locomotive in the existing fleet burns 228,000 gallons of fuel per year, resulting in the release of 241 tons of pollutants.
Officials said the new locomotives will burn about 36,500 fewer gallons while generating more horsepower. The energy savings will be about $78,000 a year per locomotive.
In June 2010, the MassDOT Board of Directors approved the purchase of an additional 20 new diesel-electric locomotives from Motive Power Inc. of Boise, Idaho, at a cost of $114 million. The 20 new locomotives will be brought into service in 2013 to replace the 20 oldest units in the fleet.
