The concrete station structure, part of a Pennsylvania Railroad grade-separation project completed in 1918 in conjunction with electrification of the line, was designed by William Holmes Cookman.

The original station building was a two-story stone structure at street level on the outbound side.

Retained in that general location after the 1918 grade separation, it was demolished circa 1958, replaced by a small brick ticket office on the inbound side which remains in use today.

It contains concrete-arch-covered staircases on all four corners of the Chelten Avenue Bridge over the tracks leading to the station platforms.
