NEW YORK (CBS 2) — Riders of the Long Island Rail Road were faced with another weekend of service disruptions, even as thousands of spectators were planning to head to the City for Sunday’s New York City Marathon.

The only trains with direct service to Penn Station will be the Long Branch, Babylon, and Port Washington Branches.

Commuters taking the Huntington, Port Jefferson, Oyster Bay, Hempstead, and Ronkonkoma branches will have to take buses for part of their trip.

The cuts come as the LIRR runs a final battery of tests to bring its World War I-era signal system into the new century.

Will it be worth the wait? “If we have a problem like the fire we had here in Jamaica in August, it gives us a way to work around that problem,” said Long Island Railroad Spokesman Joe Calerone.

The LIRR was urging people to make alternate transportation plans, and again there are buses to get you around the disruptions, but for those going into the City for the marathon, expect delays of at least 70 minutes, as you try to make your way to Penn Station.

The disruptions were expected to be over by Monday’s commute.
