A disabled diesel engine at the Carle Place station caused delays to more than four-dozen morning rush-hour trains on the Long Island Rail Road on Wednesday, the railroad said.

The breakdown occurred just before 6 a.m. The railroad said it was finally back on schedule at about 10:30 a.m.

A total of 58 trains were delayed by the breakdown, which involved the 4:55 a.m. train from Port Jefferson to Hunterspoint Avenue, a railroad spokesman said. The delays affected eastbound and westbound trains west of the Hicksville station on the Main Line.

Even after the railroad said the disabled train was moved using a so-called "rescue train," there were residual delays of up to 30 minutes before trains got fully back on schedule.

The cause of the train becoming disabled was not immediately clear, the railroad said.

During the delays, all Ronkonkoma and Port Jefferson branch westbound trains made all stops between Westbury and New Hyde Park.
