With the main blitz of the morning rush-hour over, the Long Island Rail Road said it is finally operating on or close to schedule on the Babylon Branch — after a power outage near Rockville Centre caused widespread disruptions to rush-hour trains Thursday.

At least a dozen westbound trains and one eastbound train were delayed — with average delays of up to 30 minutes, the railroad reported on its website.

Another train was canceled.

While service was back on schedule on the Babylon Branch, the rail said the 8:32 a.m. train from Port Washington to Grand Central Terminal was running late due to switch trouble. And the railroad said commuters were facing planned stops — and, skipped stations — on the Hempstead Branch and in the City Zone, both due to scheduled track maintenance and improvement projects.

The Metropolitan Transportation Authority said the outage on the Babylon Branch had the greatest impact on the morning commute, with a number of westbound trains affected by the outage.

The cause of the outage was not immediately clear.
