Worcester. There wasn't, to my knowledge, a way for B&M trains to go directly onto the B&A, until a connecting track was installed at CP-45.
Yeah, back in the early '70's, like many railroad operations in the area, the B&M-PC Worcester interchange was handled in a "yard-intensive" way, reflecting labor agreements, interchange agreements, ICC regulation governing interchange gateways and without the yet-to-come deregulation and streamlining of the '80's. In today's environment, a "run-through", or at least B&M delivery to PC's East Worcester yard, would have taken headroom down into S Worcester and shoved back through the eastward connection onto the B&A, but back then constraints dictated that the interchange be handled by both PC's S Worcester and E Worcester yards. S Worcester's switchers would forward the interchange to/from E Worcester who would switch the pick-ups and set-outs made by the road trains to/from the west. S. Worcester, IIRC, had switchers on duty 24/7, to bring the interchange to the B&M's N Worcester yard, amongst other duties, as I think it was an interchange standard back then that the delivering road would bring the interchange to the other carrier's yard and come back light. In recalling this operation, it would make sense that the B&M Worcester I/C ended in 1976 with the start of Conrail and the sale of the S. Worcester yard and Norwich branch to the P&W. I believe that traffic moving via the Worcester interchange was shifted over to Springfield at Conrail's inception until the start of 'streamlined', run-through interchange via Barbers. Under today's regulatory and labor environments, but contributiing to the loss of yards and switch jobs, carriers are able to have more control over how and where interchange occurs.
