north. Putnam and Dutchess counties North of Peekskill the river narrows as the Hudson Highlands begin. Dunderberg and Bear mountains can be seen across the river. The train passes through two short tunnels, one under the Bear Mountain Bridge abutment. Putnam County's first station, Manitou, serves a small hamlet. Just north of Garrison, there is another tunnel and then a view of the stone buildings of West Point; the riverside village of Cold Spring is the next stop, last in the county. The Dutchess County line is crossed in a pair of tunnels under Breakneck Ridge at Breakneck Point; across the river Storm King Mountain is seen. The Breakneck Ridge flag stop marks the end of the Highlands as the river once again broadens around Newburgh Bay. At Beacon, ferry service is available during peak hours to Newburgh, whose skyline is visible across the river, and shortly after leaving the train passes under the Newburgh-Beacon Bridge. Just upriver is New Hamburg, a hamlet of the Town of Poughkeepsie and a station closed in the NYCRR days but eventually reopened. The last to Poughkeepsie's recently renovated station, including the vast Tilcon quarry, is the longest distance between any two stations on a Metro-North main line. Rolling stock Electric service from and to Croton–Harmon uses the standard M3A and M7A multiple units also seen on the Metro-North Harlem Line. Diesel trains are headed by Genesis P32AC-DMs. These electro-diesels run off third-rail through the Park Avenue Tunnel. Turning the locomotives around at either end of the line would be cumbersome and time-consuming, so trains use push-pull operation with the locomotive usually on the north end of the train. They usually pull/push six or seven Shoreliner passenger cars with a cab car at the south end of the train. The Genesis locomotives are mostly in Metro-North's silver-and-blue livery, but sometimes the New York, New Haven and Hartford Railroad's red-black-white palette can be seen as equipment on the line is pooled with ConnDOT, whose red-striped passenger coaches are also in wide use on the Hudson Line. The Metro-North-owned Genesis units received a new paint scheme in 2007. Future service proposals Penn Station Access As part of the Penn Station Access project, the MTA has proposed to send some Hudson Line trains to Penn Station in Midtown Manhattan. Hudson Line trains would access Penn Station via the Empire Connection, a segment of track owned by Amtrak.
