As the LIRR enters its final phases of track work this spring, passengers can expect some service changes to go into effect on Monday and continue through May 18 on its Ronkonkoma and Montauk branches.
As part of the LIRR’s Double Track Project that is slated to be finished by the end of the summer, crews will work around the clock to connect new track to existing track and install a third rail west of the Central Islip station. Work will also be done on new track and signal systems from Deer Park to Farmingdale, and new track panels will be installed in Ronkonkoma ahead of track alignment work scheduled to start at that station in June.
Platform and overpass work will continue at the Wyandanch station as canopies and roofing are put in, and new signal huts will be placed at Farmingdale.
Due to the work, service changes will be in effect, and while most will affect off-peak service, a few rush-hour trains will be impacted from April 30 to May 18.
