The Babylon Branch is a rail service operated by the Long Island Rail Road in the U.S. state of New York. The term refers to the trains serving Montauk Branch stations from Valley Stream east to Babylon; in other words, the Babylon Branch is a rail service rather than an actual track. The electrification of the Montauk Branch ends east of the Babylon station, so the Babylon Branch is mostly served by electric trains. The west end of the "Babylon Branch" is the junction between the West Hempstead Branch and Montauk Branch (Valley Interlocking); , the only stop on the Montauk Branch west of , is shown in the West Hempstead Branch despite being served by Babylon Branch trains on weekends. Some Montauk Branch trains operate nonstop through Babylon Branch stations until reaching Babylon, though others use the Central Branch between Belmont Junction west of Babylon station and a junction at Beth Interlocking on the Main Line southeast of Bethpage Station, running to New York City via the Main Line. On weekends, Babylon Branch trains typically stop at Forest Hills and Kew Gardens in the eastbound direction as opposed to other Main Line trains that serve other branches. The Babylon Branch portion of the Montauk Branch is completely grade separated with bridges over all intersecting roadways. New York State Route 231 and the Meadowbrook Parkway are the two exceptions to this; the tracks pass under these roadways. History Early history The South Side Railroad of Long Island in the 1860s built what was to become the Montauk Branch of the Long Island Rail Road. The Babylon Branch as a separate operational entity began as the electrification of the Montauk Branch between Valley Stream and Babylon on May 20, 1925. Eventually, this would also include the former "Springfield Branch" which the Montauk Branch was relocated to northeast of Springfield Junction. Grade-separation project The tracks were elevated from ground-level between 1950 and 1980. Elevation of the line sparked grass-roots efforts to preserve the previous versions of Wantagh and Lindenhurst Stations, the former of which resulted in the creation of the Wantagh Railroad Museum. The last station to be elevated on the branch was Massapequa Park on December 13, 1980. On December 30, 1968, the first revenue train of M1 cars departed Babylon for Penn Station. In anticipation, all stations that were still at grade level had their platforms converted from low-level to
