MBTA FP10 1150 leads a trio of former New Haven coaches on a Boston-Framingham commuter train rolling through Weston, MA, on the former Boston & Albany. The wisps of steam coming from the cars shows that the 1150 was one of four FP10s delivered with steam boilers for use with steam-heated coaches, later rebuilt with HEP.
The 70's and 80's were a transition period for the MBTA characterized by an eclectic mix of equipment including Budd RDC's, ex-New Haven stainless steel coaches, and a mix of motive power acquired from various railroads.
