became the freight route, and when the present Jamaica station opened in 1913 the two Lower Montauk tracks continued past the south side of the station, south of Hall tower and the south Union Hall Street platform and on to Holban Yard. Those two tracks now carry trains to/from the Hillside Facility that has replaced Holban Yard; they can also carry nonstop Main Line trains past Jamaica station. East from Jamaica the Montauk Branch runs between the Main Line tracks (with two usually westward Main Line tracks north of it and two eastward tracks south of it) until just west of Hillside Facility. At the Montauk Branch rises to cross above the other tracks and turns southeast. At it swings parallel to the Atlantic Branch between its Laurelton and Rosedale stations. The Montauk Branch east of Jamaica is 0.7 mile longer than the Atlantic. Babylon Branch The portion between Jamaica and Babylon stations has been electrified since 1925, and electric trains to Babylon are often identified as a separate service, the Babylon Branch. It is grade-separated on embankments or elevated structures. From Babylon east to Montauk, diesel-electric or dual-mode electric/diesel-electric locomotives haul trains of passenger coaches. The Montauk Line has heavy ridership and frequent service as far as Patchogue station and commuter service as far as Speonk station. In the summer, with travelers going out to The Hamptons, Fire Island and other beaches, additional service is operated to the far eastern terminal at Montauk, such as the Cannonball, a Friday afternoon train departing from Penn Station (originally Hunterspoint Avenue) and running non-stop to Westhampton station in Westhampton. The Montauk Branch, along with the parallel Atlantic Branch, spawns three subsidiary branches: the West Hempstead Branch, Far Rockaway Branch, and Long Beach Branch. The electrified portion of the Montauk Branch ends in the village of Babylon. Some of the diesel trains on the Montauk branch begin or end their runs at Babylon station, connecting with electric trains there. Other Montauk diesel trains operate into New York City, to Jamaica station; Hunterspoint Avenue or Long Island City stations in Long Island City; or Penn Station. East of Babylon The terminal stations in diesel territory, east of Babylon, are Patchogue, Speonk, and Montauk. The Montauk Branch is double-tracked from just east of Long Island City (where there is a short segment of single track) all the way through Babylon, becoming single track at Y
