***"I wonder if the BOT was undecided weither to extend the line east on Pitkin Avenue thereby roughly parrelling and possibly replacing the Fulton Street El.(In a similar way that the Archer Avenue Line replaced the Jamaica Avenue El). It is intersting that provisions where provided for two extensions."***
Larry,
I know your much more researched then I am on Subway matters, but
using the "Projected Extensions Map" from the BOT to the city planning commission,
dated July 5, 1939 it shows the two branches past Euclid Avenue.
The line going onto the Fulton El at Grant Avenue as built, AKA "Liberty Avenue Line"
to Lefferts Blvd, as built.
Also the Fulton Street Extension to 229th Street.
On this extension it also shows a connection to the Rockaway Line
coming from Queens Boulevard Line to the Rockaways, as now served.
So the takeover of the LIRR Rockaway service by the Subway was imminent.
The 1950 fire of the trestle just expedited the takeover.
Also wasn't the extension of the Fulton Street line beyond East New
York underway and delayed by WWII?
Truth or Fiction, the map is dated 1939 and I purchased same with
the "Twelve Historical NYC Street and Transit Maps" Volume II.
Some other interesting proposals on this map also, that never came
to fruition.
