The 1912–1928 Cambridge-Dorchester fleet remained in service until 1963, when it was replaced all at once by 92 married-pair cars from Pullman-Standard numbered 01400–01491.
These carbon-steel cars were originally delivered in a blue, white and gold paint scheme (the state colors of the Commonwealth of Massachusetts, which funded their purchase),  and retained that color scheme into the early 1980s when most were finally repainted into Red Line colors for the opening of the Alewife Extension.
The 01400s (or 1400s) were the last pre-MBTA transit cars and also the last ones built without air conditioning.
All were retired from passenger service by 1994 due to mechanical and electrical equipment not being able to operate with six-car trains.
With delivery of the 1800-series, four cars (01470/01471 and 01480/01481) remain as Red Line work equipment, and 01450 and 01455 are preserved at the Seashore Trolley Museum in Kennebunkport, Maine.
