Pennant Hills railway station is a suburban railway station located on the Main North line, serving the Sydney suburb of Pennant Hills.

It is served by Sydney Trains T9 Northern Line services.

[3] Immediately north of Pennant Hills, a short four track section of the Main Northern line begins which runs to the next station at Thornleigh.

[4] The present day footbridge was built in May 1991 and Pennant Hills received an easy access upgrade including lifts on each platform, becoming one of the first low-patronage stations in Sydney to receive wheelchair access, along with Waverton.

As part of the North Sydney Freight Corridor project, an electrified passing loop was built behind the western platform where it joined the existing loop.
