on the Long Island Rail Road that does not have signals. The relatively small amount of train movements on this segment are governed by train orders and timetable authority. This segment is served by diesel-electric "scoots", most of which terminate at Ronkonkoma, requiring customers traveling west of Ronkonkoma to transfer there. Three eastbound and four westbound scoots travel each weekday between Ronkonkoma and Greenport. Also, one additional round trip is scheduled between Ronkonkoma and each weekday. Weekend service consists of four round-trips each day between Ronkonkoma and Greenport. On Fridays during the summer, the eastbound trip to Yaphank is extended to Greenport, and one additional evening trip runs from Greenport to , running express between Ronkonkoma and Jamaica. Added in summer 2016, this is the only Greenport scoot trip to serve the New York City terminals. The Greenport Branch has by far the lowest ridership among LIRR services for which data is available. In 2018, the LIRR's second–least used service (the West Hempstead Branch) had more than 14 times as many riders as the Greenport Branch did; in the same year, Greenport Branch riders accounted for 0.08% of LIRR ridership overall. The LIRR has cited these ridership trends in attempts to end service east of Ronkonkoma. In 2010, the idea was entertained by the financially troubled MTA, who proposed eliminating all scoot service except for the popular summer weekend service. Ultimately, weekday service remained, but weekend service outside of the summer season (defined as Memorial Day-Columbus Day) was discontinued. In 2013, the span of weekend service was extended to operate from the first weekend in May to the last weekend in November. In 2016, the LIRR restored year-long weekend service between Ronkonkoma and Greenport. Central Branch Some LIRR maps also include as part of the Ronkonkoma Branch the non-electrified Central Branch, which splits from the Ronkonkoma Branch east of Bethpage and connects with the more southern Montauk Branch, just west of Babylon. There are no stations along this stretch, and it is mainly used by trains with diesel-electric engines going express from Jamaica to Babylon. No trains using this track appear on Ronkonkoma Branch schedules; they appear on Montauk Branch and Babylon Branch schedules, and some appear on schedules for Mineola and Hicksville on the Main Line, if a stop is scheduled there.
