Hi Bob
Thanks for posting that photo. I am thinking that this the 39th street yard on the SBK . Its still there but diesels do the work now . Cars can still be received and sent out to and from the Subway system.
The R-17's started arriving in 1955 . Most went to work on the Lexington Pehlam line . There were a few that did come to the Flushing Line for a short period in the 1950's . Heres a Photo of R-17's at Willets Point.
After the 2nd ave el closed in 1942, The Flushing Queens IRT operation was isolated from IRT operations in Manhattan so Coney Island became the base for heavy repairs of their equipment for this line. When cars were sent to and from the IRT routes in Manhattan, they did go by car float to Bush Terminal and then stret running via SBK to the SBK's operation at 39th street. These are LoV's from the Flushing line heading to the Bronx in this photo
