Eastbound service on the Long Island Rail Road was running on or close to schedule systemwide, but westbound service faced scattered delays of 10 to 15 minutes due to a signal problem at the West Side Yard.

Crews were on site working on the issue, a spokesman said, who could offer no further detail.

That comes on the heels of a suspension late Monday morning on part of the Ronkonkoma Branch due to a gas main leak in Brentwood, with service since restored.

Earlier Monday, a construction crew digging to install a fire hydrant accidentally struck a gas main in Brentwood, causing a leak that forced road closures and the service suspension, gas company and rail officials said.

The incident occurred at 10:27 a.m. near the intersection of Fifth and Third avenues, about 500 feet south of the railroad tracks.

National Grid spokeswoman Wendy Ladd said crews had completed repairs, with the site deemed secure at 1:14 p.m. Ladd said a Suffolk County Water Authority crew struck and ruptured an underground 8-inch main. A National Grid contractor mismarked the main, she said.

Multiple roads were closed, with most reopened by midafternoon, Suffolk County police said.

The temporary service suspension came after a weekend bridge demolition caused service to be suspended between Hicksville and Mineola.
