The 2nd of two new state-of-the-art diesel-electric locomotives purchased from the Utah Transit Authority rolled into service at South Station today, the first new locomotives to join the MBTA’s commuter rail fleet in more than 20 years. The first of the two began service earlier this month.
New technology makes the engines more fuel efficient and prevents unnecessary idling, burning about 36,500 fewer gallons while generating more horsepower.
The MassDOT Board of Directors in 2010 also approved the purchase of an additional 20 new diesel-electric locomotives 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.
The MBTA commuter rail fleet operates under a contract with the Massachusetts Bay Commuter Railroad Company. The fleet consists of 410 coaches including 140 bi-level and 270 single coaches, and 80 locomotives. The fleet ranges in age from seven to 29 years. Commuter rail service carries approximately 148,000 customers round-trip each weekday.
