A week after superstorm Sandy churned ashore, Hudson Valley rail commuters will find an expanded menu of mass transit options Monday from Metro-North and the New York City subway system.

Metro-North will resume service on its branch lines Monday, the Metropolitan Transportation Authority announced. Service will resume on the Wassaic branch, with regularly scheduled trains between Southeast and Grand Central Terminal.

The New Haven line will restart service on the Danbury and Waterbury branch lines.

Gov. Andrew Cuomo said Sunday that the MTA has restored 80 percent of the New York City subway system, including service between Brooklyn and Manhattan, which had been severed by Sandy's floodwaters.

"This is a major step forward in the resumption of regular subway service in New York City," Cuomo said in a statement. "Once again, subway customers have a direct link between Brooklyn and Manhattan, giving them a fast and reliable way to get to their jobs, their schools and their homes."

Workers trying to go from Brooklyn into Manhattan last week faced massive delays as they tried to board shuttle buses or cross bridges on foot.

Among the subway lines returning to service are the 4, 5, 6 and 7. The F began operating between 179th Street and Avenue X. The 1 train has been extended south to 14th Street and the 2 line is now running from 241st Street in the Bronx to Flatbush Avenue in Brooklyn.

The Newburgh-Beacon and the Haverstraw-Ossining ferries also will return to service for the Monday morning commute.

On the Port Jervis line operated by NJ Transit, partial service is in effect, with four morning peak and four afternoon/evening peak trains making all local stops to Secaucus.

On Saturday, Metro-North extended service on the Hudson line from Poughkeepsie to Grand Central.
