This abandoned railway line was originally part of the Delaware Lackawanna and Western and then became part of Erie Lackawanna, and was known as the Richfield Springs Branch. In 1973, Delaware Otsego purchased it and it was known as the Central New York Railroad, a Delaware Otsego subsidiary. The Central New York operated the line until 1995, when it was abandoned due to lack of customers.

The line ran south from Utica to Bridgewater where it interchanged with the Unadilla Valley Railroad until that line was abandoned in the 1950s. From Bridgewater, the branch turned east to East Winfield, West Winfield, Cedarville, Millers Mill, South Columbia and ending at Richfield Springs.
