Bath is served by the Bath & Hammondsport Railroad which operates over former Delaware, Lackawanna & Western mainline trackage between a connection with Norfolk Southern in Painted Post, and the company's terminus in Cohocton. The Erie Railroad's Rochester Division once passed through Bath. The 1960 merger of the Erie and DL&W led to the creation of Erie-Lackawanna which was followed by the elimination of redundant trackage. The Erie line through Bath was abandoned, as was much of the DL&W west of Wayland. The result was a drastic reduction of railroad activity in Bath since traffic could be routed over the parallel ex-Erie mainline through the Canisteo River Valley. Erie-Lackawanna was absorbed into the Consolidated Rail Corporation in 1976. In 1999, Conrail lines in the region were acquired by Norfolk Southern. Since then, the Bath & Hammondsport has become a subsidiary of the Livonia, Avon & Lakeville which currently operates the line, though not over any of its original route. Trains operate through Bath five days per week. The Conhocton River flows through Bath, and Lake Salubria is a small artificial lake southeast of the village.
