The Montauk branch was operating on or close to schedule at the end of the Monday morning rush hour after track damage earlier near Mastic-Shirley resulted in a suspension of service and residual delays averaging 90 minutes.

The Long Island Rail Road said the branch was on or close to schedule in an email alert shortly before 10:30 a.m. Service was restored to the branch at about 8:30 a.m.

The LIRR had suspended service in both directions east of the Patchogue station after suspending it at about 7 a.m. because of a track condition.

Just before it suspended service, the LIRR said the track condition was debris on the track west of Mastic-Shirley station. Later, spokesman Aaron Donovan said the condition was a “misaligned piece of track.”

Overall, the morning rush hour had about 10 delays and at least one canceled train because of the track condition on the Montauk line and a broken rail near the Copiague station, Donovan said.
