Three separate safety-related projects on the Long Island Rail Road’s tracks will result in service disruptions for some riders beginning this weekend, the LIRR said.
Over the next three weekends, buses will replace trains along portions of the Port Jefferson line as the railroad replaces concrete rail ties between Huntington and Port Jefferson — an effort the LIRR said will ensure “continuing safety and reliability” along the branch.
The work will be done Saturday and Sunday, the evening of Oct. 20, all day Oct. 21, and Oct. 27-28.
Other service changes will affect the railroad’s Montauk branch, beginning Monday and lasting into next month.
Buses will replace some midday weekday trains between Babylon and Montauk between Monday and Oct. 19, and also Oct. 29 and Nov. 2.
The railroad said the service changes are necessary as it performs rail safety tests and also continues its installation of positive train control technology.
The rail tests will be performed by a Sperry Rail Car, which uses ultrasonic and induction technology to detect internal defects in rails not visible to the human eye, the LIRR said.
“Defects that are found will be corrected immediately by LIRR track maintenance workers,” the railroad said.
Positive train control, or PTC, works by having radio transponders that are installed on tracks and trains communicate with one another to automatically slow down or stop a train if it’s going too fast, is about to hit another train, or violates a signal. Federal law requires railroads to have made significant progress in installing PTC throughout their systems by the end of 2018.
Also this weekend, the LIRR will provide extra service along its Oyster Bay line for people traveling to and from the 35th annual Oyster Festival in Oyster Bay Village. The LIRR will operate three extra eastbound and westbound trains from 11 a.m. to 7 p.m., and also an additional westbound train leaving Oyster Bay at 8 p.m. for those staying late to watch a fireworks display.
