The Rhinebeck and Connecticut Railroad (R&C) was a railroad in Dutchess and Columbia counties in New York, United States. Its line ran 35 miles (56 km) east from the Hudson River at Rhinecliff to Boston Corners. It was chartered in 1870 to connect the Connecticut Western Railroad with the Hudson River to transport coal mined in Pennsylvania. Construction began in 1871, with the line opening in stages from 1873 to 1875. The railroad went bankrupt in 1881; it was purchased the next year by Connecticut Western successor Hartford and Connecticut Western Railroad (H&CW).

The Ulster and Delaware Railroad (U&D) was a railroad located in the state of New York. It was often advertised as "The Only All-Rail Route to the Catskill Mountains." At its greatest extent, the U&D extended 107 miles (172 km) from Kingston Point on the Hudson River through the Catskill Mountains to its western terminus at Oneonta, passing through the counties of Ulster, Delaware, Schoharie and Otsego.
