Scarsdale is the southernmost station on the two-track section of the Harlem Line; a third track begins to the south.

Scarsdale is the second busiest Metro-North station in Westchester County, after White Plains.

[7] The existing station house was built by the New York Central and Hudson River Railroad in 1904 (although some evidence dates it back to 1902) in the Tudor Revival style.

Penn Central's continuous financial despair throughout the 1970s forced them to turn over their commuter service to the Metropolitan Transportation Authority, and it officially became part of Metro-North in 1983.

The station has been on the National Register of Historic Places since the year 2000, and faced a restoration project in 2007.
