The Long Island Rail Road was operating on or close to schedule Tuesday night, after service was briefly suspended on two branches during the evening commute.

A spokesman said the problems that led to the suspensions on the Long Beach and Far Rockaway branches stemmed from signal troubles at Valley Stream, but both lines were operational — though experiencing delays up to an hour — shortly after 7 p.m. Tuesday.

The LIRR tweeted shortly after 8 p.m. Tuesday that the system was on or near schedule, with only scattered, residual delays related to the signal trouble.

LIRR spokesman Salvatore Arena said that the earlier interruption caused 10- to 15-minute delays on other branches, including the Babylon, Hempstead and Montauk lines.
