The crane is ex-New Haven and belongs to the Bay Colony. I don't think they ever used it. Inherited from CR.
The PC gondola and the ex-NYC double door Early Bird boxcar showed up during the Conrail era. The gondola was used in MW service and never left! The boxcar was used to store a variety of stuff when Middleboro serviced engines, etc. The RR museum in Fall River tried to get both cars, but CR would not move them due to friction bearing trucks.
