Interlocking east of the Sayville station. Some Montauk Branch diesel trains operate west to NYC via the diesel-only Central Branch, joining the Main Line east of Bethpage station. Only a few actually run via the Montauk Branch west of Babylon, under normal conditions on the Main Line. The Montauk was home to the last tower in North America that regularly used "hooping" train operations: PD Tower, in Patchogue. "Hooping" is the transfer of instructions to the engineer and conductor by attaching the folded orders to the "hoop", a rod several feet long with a loop at the end that is passed from the ground to a moving train by catching the loop on one's arm. The last train to get hooped at PD was train 2730 on May 6, 2006. History Currently, the Montauk Branch intersects with the Bushwick Branch, Bay Ridge Branch, West Hempstead Branch, and Central Branch, as well as the Main Line at Long Island City and Jamaica and the Atlantic Branch at Jamaica and Valley Stream; the Far Rockaway Branch and Long Beach Branch are connected via the Atlantic Branch at Valley Stream. In the past, junctions existed with the Rockaway Beach Branch (a quarter mile east of Woodhaven Boulevard), Southern Hempstead Branch (Valley Stream to Hempstead), Manorville Branch (Eastport to Manorville on the Main Line), and Sag Harbor Branch (Bridgehampton to Sag Harbor). In early times, the Scoot ran frequently between Greenport on the North Fork, "around the horn" on the Manorville Branch, and east to Sag Harbor. In their day, both of those villages were very busy, bustling ports. Formation and early days: 1860s to 1925 The South Side Railroad of Long Island built the line from Bushwick, Brooklyn to Patchogue in the 1860s, and completed the new line to Long Island City in 1870. With the reorganization of the South Side as the Southern Railroad of Long Island in 1874 and its lease by the LIRR in 1876, this line became the Southern Railroad Division, Southern Railroad of Long Island Division, or simply Southern Division. Effective Sunday, June 25, 1876, all Southern Division passenger trains were rerouted to use the LIRR main line from Berlin Junction (west of Jamaica) to Rockaway Junction, and the LIRR's Rockaway Branch to Springfield Junction, where it crossed the Southern. This change resulted in the closure of the Southern's Berlin, Beaver Street (Jamaica), Locust Avenue, and Springfield stations.
