Service on the Long Island Rail Road was disrupted for almost a half-hour during the Wednesday morning commute because of Amtrak signal trouble in one of the East River tunnels, the railroad said.

The railroad issued a service alert about the disruptions at 7:30 a.m. and said shortly before 8 a.m. that service was returning to normal. Trains were on or close to schedule by about 9:30 a.m.

At least four westbound trains were terminated at Jamaica and one train was diverted to Atlantic Terminal in Brooklyn, the LIRR said on its website.
