Delaware and Hudson Railway

The Delaware and Hudson Railway (D&H) (reporting markDH) is a Class 1 railroad that operates in the Northeastern United States. In 1991, after 168 years as an independent railroad, the D&H was purchased by the Canadian Pacific Railway (CP). The Delaware & Hudson is a wholly owned subsidiary of CP, which would itself become part of Canadian Pacific Kansas City in 2023. CPKC operates the D&H under its Soo Line Corporation subsidiary, which also operates Soo Line Railroad.

D&H's name originates from the 1823 New York state corporation charter listing "The President, Managers and Company of the Delaware & Hudson Canal Co." authorizing an establishment of "water communication" between the Delaware River and the Hudson River.

Nicknamed "The Bridge Line to New England and Canada," the D&H connected New York with Montreal and New England. The Delaware & Hudson has also been coined as "North America's oldest continually operated transportation company." In 2023, the D&H turned 200 years old.

On September 19, 2015, the Norfolk Southern Railway completed its acquisition of the "D&H South Line", which is 282 miles (454 kilometers) long, and connects Schenectady, New York, to Sunbury, Pennsylvania. The D&H South Line consists of three rail lines, the Sunbury Line, the Freight Line, and the Voorheesville Runner (former Albany & Susquehanna Railroad Mainline between Delanson and Voorheesville, NY). The Nicholson Cutoff is located on the Sunbury Line, which was the former mainline of the Delaware, Lackawanna and Western Railroad.
