MTA overstates cost of restoring long-abandoned Queens tracks that could speed commutes, says report
A set of railroad tracks abandoned a half-century ago may be key to speeding up commutes for tens of thousands of Queens residents — but a report published last month by an advocacy group suggests the MTA has no interest in moving the project forward.

I like the idea of running subways over the old line, much like the segment from around Aqueduct Race Track/JFK Airport and the Rockaways is now by the A train. While they would essentially extend the M train beyond its current terminus under Queens Blvd. in Forest Hills over the Rockaway Branch, interline with the A, and then take over the S Shuttle line to Rockaway Park, I think it would be better to reorganize some lines to run another route over the branch. The M line already almost meets itself on its circuitous route from Queens to Queens via Manhattan, and this would make it even more of an unlikely route that anyone would ride end to end.
