The station has one eight-car-long high-level island platform serving trains in both directions. A bridge over the Muscoot Reservoir for Lakeside Road north of the Lakeside Road parking lot was converted into a connecting ramp from Interstate 684 at the southbound on-ramp of exit 6, but was later closed. A small waiting room was maintained for passengers through 1984, when Metro-North opened its new station immediately north of Jay Street crossing. In 1954, New York Central closed the ticket agency in the Katonah station, and the building was later sold to private owners. A second station (picture on the left) was built in 1910 to replace it.

The original depot at Katonah was moved from its location in 'Old Katonah' in 1897, prior to the flooding of the Croton River valley for the New Croton Reservoir, which is today a private residence in the village of Katonah.
