Long Island Rail Road trains on the Babylon Branch were delayed and canceled Monday because of signal system damage from a downed PSEG Long Island transmission line, officials said.
A spokeswoman did not have more details on the extent of the damage or whether Tuesday morning’s commute will be affected.
A transmission line fell onto the LIRR tracks near the Freeport station around 4:30 a.m. Monday and was removed by 5:45 p.m., officials said.
At least 30 trains were delayed or canceled by 9 p.m. as trains operated on one of two tracks at Freeport, officials said.
Delays averaged 30 minutes after the wire was removed because of damage to the signal system, which crews are working to repair, the LIRR said.
“If possible, customers may consider taking alternate branches, such as the Long Beach, Hempstead, Port Jefferson, or Ronkonkoma branches,” the LIRR said on Twitter.
PSEG spokesman Jeremy Walsh said the agency is investigating the cause of the transmission line’s failure.
Crews did not begin efforts to remove the line until about 4 p.m. because MTA and PSEG officials had to coordinate on which equipment to turn off and how to limit train service disruptions, Walsh said.
Officials had to de-energize two other area lines “in order to make the area safe for the crews to do their work,” Walsh said. Power was restored to those lines at 6:11 p.m.
Third rail power had also been deactivated, which earlier caused the LIRR to limit diesel service between Jamaica and Babylon, officials said.
