Joe, that is a nice picture, but rather than saying that it is heading north, it should be said that it is heading toward the wye and toward Pond.
Jay!!!!
You say that the bay Ridge branch was not always the property of the LIRR???
You are right, but it was not owned by the PRR until that road took over the stock of the LIRR in the early 1900s.
Austin Corbin was the driving force behind the New York and Manhattan Beach RR and when he became president of the LIRR, he merged his NY&MB into the LIRR.
In the 1960s, when the MTA was formed, the state of New York bought the LIRR but did not want the Bay Ridge branch.
This left it in the ownership of the PRR, PC and finally CR.
I don’t know the particulars, but in the mid ‘80s it fell back to MTA & LIRR ownership.
