The Hudson Line on Metro-North was experiencing delays of up to 50 minutes Saturday evening following a fire, officials said.
Delays were up to 50 minutes in both directions as of 6 p.m., the MTA said.
Only one track was being used after a fire caused damage to a third rail and cut electricity. Single-tracking was in effect from Morris Heights to Marble Hill in the Bronx, MTA spokesman Aaron Donovan said.
Electricity was eventually restored to the affected track, but delays continued. Service had returned to normal by 8 p.m.
Four trains had been delayed for 30 minutes and four to six trains were delayed for 15 minutes, Donovan said.
