Boston [US] - Modernization of DUO buses

K. Budach - 15.12.14

Skoda Electric has been contracted by the Massachusetts Bay Transportation Authority (MBTA) to modernize the 32 DUO trolleysbuses which were delivered between 2004/2005. The mid-life overhaul of these articulated trolleys, which are used on the “Silver Line” BRT system, has a value of 3.62 million EUR. Skoda will cooperate closely with the local, Boston-based company MMA, which is charged with the revamp of the bus bodies and vehicle interiors.

The Silver Line runs from Logan International Airport by tunnel to the waterfront and city center using electric traction. From there it continues to Chinatown and the terminus Dudley Square in Roxbury using the diesel drive. In total, 4 different bus routes are grouped within the Silver Line label. The mini-network opened in phases between 2002 and 2004. It is not directly linked with the MBTA’s traditional trolleybus system in neighboring Cambridge, on the other side of the Charles River. Specifically, the DUO buses run on:

SL1: South Station - Waterfront - Logan Airport - 8 mins
SL2: South Station - Waterfront - Design Center - 5/10 mins
