The Long Island Rail Road canceled all trains in both directions Sunday night because of the weather.
While it planned to operate trains Monday on a holiday schedule, it warned passengers to watch its website for updates.
The LIRR originally had suspended eastbound service on most Long Island lines because of switching problems near Jamaica. Service on the Port Washington line was not suspended. But as weather grew worse and the accumulation of snow increased, the railroad halted all trains.
The LIRR said that the Metro-North Rail Road, NYC bus and subway service and Long Island Bus service is running on or close to schedule, weather permitting.
