The Adirondack is an intercity rail passenger train operated daily, partially along the Empire Corridor, by Amtrak between New York City and Montreal. The trip takes approximately 11 hours to cover a published distance of , traveling through the scenic Hudson Valley and along the eastern border of the Adirondack Mountains. The Adirondack is financed by the New York State Department of Transportation. Service was suspended in March 2020 due to the closure of the Canadian/American border in response to the COVID-19 pandemic; weekday service returned between New York City and Albany resumed on December 5, 2022. Full service is expected to resume in Spring 2023. For most of its existence, the Adirondack has been plagued by numerous delays. Amtrak only owns two legs of the route, in Manhattan and between Poughkeepsie and Schenectady. Additionally, the route crosses an international boundary where immigration procedures can take up to two hours. The on-time performance of the route averaged 64.8% for the year ending June 2016. According to Amtrak, 28.8% of the train delay was due to track- and signal-related problems, especially along the Delaware & Hudson segment, which is now owned by Canadian Pacific Railway. History At the inception of Amtrak on May 1, 1971, the Delaware & Hudson operated two trains between Albany, New York and Montreal: the Montreal Limited (overnight) and the Laurentian (day). Both trains were discontinued, and for three years the D&H line saw no service. Amtrak service to Montreal began with the Montrealer, which ran through Vermont rather than New York, in 1972. The Adirondack began running on August 6, 1974 (with a ceremonial train the previous day) from Grand Central Terminal in New York to Albany, then over the D&H's line to Windsor Station in Montreal. From the outset the train operated with financial support from the state of New York. The train initially operated as a section of the New York–Buffalo Empire State Express. The Adirondack used CP Rail's Windsor Station until January 12, 1986, when it was rerouted to CN Rail's Central Station. Until the Empire Connection was built in 1991, the train served Grand Central Terminal instead of Penn Station in New York City. As part of an effort to improve on-time performance along the Empire Corridor, Amtrak reached an agreement with CSX to lease the CSX Hudson Subdivision between Poughkeepsie and Schenectady. Starting in 2012, Amtrak effectively took operational control of
