Sadly, the QBT RR is no more.
The line to the shipyard is now run by Fore River Transportation, a subsidiary of Twin Rivers Technologies.
The following was written by a friend of mine, Paul Cutler III, for another railroad discussion forum. I hope you find it interesting.
Fore River Railroad
The Fore River Railroad (FRR) is still in business today, owned by the State of Massachusetts (Massachusetts Water Resources Authority: MWRA) and operated by Fore River Transportation (FRVT), a state contractor. FRVT is a subsidiary of one of their customers, Twin Rivers Technology (which is the former Proctor & Gamble plant at Quincy Point). Their locos are a pair of ex-Conrail B23-7's, #101 and #102, painted all black with a white and teal sill stripe (Twin Rivers company colors). See link for pictures: www.geocities.com/Paris/S...photo.html
Before FRVT took over, the FRR was operated by another state contractor for 15 years or so, Quincy Bay Terminal Co. (QBT). QBT's loco fleet was at one time #19 (S-4), #20 (SW9), #21 (U23B), #22 & #23 (B23-7's). See link for pictures: www.geocities.com/Paris/S...photo.html

Before QBT, FRR was owned by General Dynamics, and before that, Bethlehem Steel. And even earlier, they were owned by the Fore River Shipyard's original owner, Thomas Watson of Alexander Graham Bell fame. The FRR did, at one time, lease NH switchers for a while back in the steam days (I've seen a shot of what looks like a T-2b crossing Quincy Ave.)
There are two FRR engines still in the shipyard, #17 (S-6) and #18 (S-4), and both are in Bethlehem Steel colors of yellow and black. #18 has been sold to the Old Colony Museum in Fall River, but they are having all kinds of trouble getting it to Fall River (it may be cut up for scrap). #17 is in working order and could be used if FRVT and the State could work out who pays for what.
FRVT's main business is loads shipped out of fatty acids made by Twin Rivers (a soap ingrediant), and converted fertilizer made from human waste manufactured by New England Fertilizer Co. (NEFCO) for the MWRA.
The FRR is also semi-famous on the NH because supposedly, one of it's engines being towed caused the sparks that set the Neponset Bridge on the Old Colony on fire, which cut off any chance for a renewal of commuter rail service until the late-1990's.
Finally, there is a former PRR N-5 caboose on the property that's owned by the employees of the FRVT. This is used for long back-up moves going to Twin Rivers or going to Braintree yard. It's in former QBT colors, which is Maine Central Harvest Gold with Maine Central Green for trim.
