Rensselaer Rail Station, signed as Albany–Rensselaer on its platforms, is a train station in Rensselaer, New York, located 1.5 miles (2.4 km) from downtown Albany across the Hudson River. Operated by the Capital District Transportation Authority, it serves as Amtrak's primary station for the Capital District. To emphasize the station's location across the river from Albany, as well as to distinguish from the Rensselaer station in Indiana, Amtrak refers to the station as "Albany–Rensselaer." It is served by Amtrak's Empire Corridor routes, including the Lake Shore Limited, whose Boston and New York sections diverge at the station. As of 2020 it was Amtrak's ninth-busiest station, as well as the busiest to serve a metro area with a population smaller than 2 million– a distinction it has held since at least 2010. This is primarily due to the large number of passengers who commute to and from New York City.
