Long Island Rail Road commuters endured train cancellations and delays sparked by a third-rail power problem in the East River tunnels at the height of the Wednesday morning rush hour commute.

The LIRR briefly suspended service between its Jamaica hub and Penn Station at about 8 a.m., which was enough to spark nine train cancelations between the Long Beach, Babylon, Port Washington and Huntington branches.

Some of those trains were immediately replaced with alternate trains. A West Hempstead train was diverted to Hunterspoint Avenue when the issue initially arose.

The LIRR reports service was restored mostly back to normal later the same morning.
