Niagara Subdivision

The Niagara Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of New York. The line runs from Buffalo north and west to Niagara Falls along former New York Central Railroad and Lehigh Valley Railroad lines. Its south end is at the Buffalo Terminal Subdivision; its north end is just east of the Canada–US border at Whirlpool Bridge, at the CSX Transportation Niagara Falls Yard. It junctions the Belt Subdivision in Buffalo and the Lockport Subdivision east of Niagara Falls.

Amtrak's Maple Leaf operates over the entire Niagara Subdivision; the Empire Service uses the line up to the border at the Niagara Falls station.
