In NYC at Sunnyside Passenger Yard they have a reversing loop. It is
accessible from the two southern tubes of the four tube East River Tunnels.
Amtrak usually uses only those two tubes. LIRR uses all four. Trains simply
pull out of Penn Station through one of the two southern tubes, go around
the reversing loop into the Sunnyside Yard for storage and servicing. The
reversing loop branches out to the southern side of the main, ducks under
the Amtrak and LIRR main line just before the bifurcation between the LIRR
main to Jamaica/Port Washington and the Amtrak main to New Rochelle across
the Hell Gate Bridge, and then enters the Sunnyside Yard (which is on the
northern side of the main lines) from its east end. The East River Tunnels
are at the west end of Sunnyside.
