The Metropolitan Transportation Authority (MTA) yesterday announced major progress on implementing positive train control (PTC) on MTA Long Island Rail Road (LIRR) and MTA Metro-North Railroad lines. 

The progress reaffirms both New York railroads will be in full PTC operations by the end-of-2020 federally mandated deadline, MTA officials said in a press release. 

Metro-North recently implemented wayside PTC operability on its entire system east of the Hudson River, including the New Haven Line from Greenwich to New Haven, Connecticut.

All Metro-North’s diesel trains, as well as its electric trains on the Harlem and Hudson lines, are operating in PTC. Technicians are bringing PTC software to the New Haven Line’s M8 electric cars, which will enable New Haven Line trains to enter PTC operations in October, MTA officials said.

Meanwhile, all LIRR cars now have the equipment and software to operate in PTC. Technicians are continuing to review performance and perform quality checks on a train by train basis to ensure that all trains are operating in PTC by the end of the year.

The LIRR has brought full PTC functionality to 94 percent of its track mileage. The remaining 6 percent is within areas of switching complexes at Jamaica Station and at Harold Interlocking, a complex of switches in Sunnyside, Queens, where LIRR meets Amtrak’s Northeast Corridor tracks for the connection to New York Penn Station.
