Hi Ben
At the time of this wreck, the BRT operated the Brighton Line to Manhattan via the Fulton El . Sands Street and Park row in Manhattan. There was an on grade turnout that connected the Franklin Ave Shuttle portion of the Brighton Line to the Fulton El. The Brighton Subway connection via Dekalb Ave, Atlantic Ave and the run to Prospect park opened in 1920. At this time, Subway service was established from Coney Island/Brighton Beach via the new connection , over the Manhattan Bridge and up the Broadway Manhattan subway. There was a station at Myrtle Ave used by Brighton Locals. It was eliminated with the Dekalb Ave rebuild.
Sometime after the new connection was placed in service, the operation via the Fulton El was eliminated creating the Franklin ave Shuttle. There waas a through service from There that operated through Stillwell ave and went express into downtown Brooklyn via the sea Beach line and 4th ave subway. From there it went to Manhattan Chambers street either via the tunnel or the South side tracks on the Manhattan Bridge depending on the time of day. It was a popular Coney Island service during the summer months . The Southbound track at malbone st was used when these services were in operation and probably when the 1967 NX service operated from Franklin ave for a brief period.
In the photos attached , There is Green Hornet heading west on the Fulton El . You can make out the crossover and Franklin connection just west of the train. The second photo shows the Fulton El Franklin Ave Station structure with walkways and stairs from the Franklin ave shuttle in 1942. This structure was there for at least 10 more years as I can remember.
