[1] The main station building, dating to 1859, was designed by William Tite and is Grade II listed.

Havant New, to the south, was a temporary station built during an inter-company dispute - the Battle of Havant; Woodcroft Halt, to the north, was open for a few years round World War 2, mainly for service personnel.

Formerly there were goods and coal sidings trailing off the Up Line at the Petersfield end of the station.

There was only one crossover between the two running lines, which meant that goods trains that arrived from the Petersfield direction (usually on the 0450 Goods Woking to Rowland's Castle) had to "set-back" into the headshunt and "fly shunt" (i.e. run off) wagons into the sidings rather than propelling them.

The station has two tracks, and two platforms, and the standard service is hourly to both Portsmouth and Waterloo.
