An MBTA Commuter Rail train heads south through Lawrence, MA on its way to Boston North Station. The Massachusetts Bay Transportation Authority has been responsible for all commuter rail operations out of Boston since the mid 1970s. Today, the agency owns over 100 locomotives and nearly 500 passenger cars which transport passengers across 13 different lines radiating out of downtown Boston. #trains #transportation #boston #MBTA #commuter | Coasterfan2105
