Harman's Cross is the location of Harman's Cross railway station, one of the intermediate stations on the Swanage Railway, a steam locomotive operated heritage railway. The railway links the tourist centres of Corfe Castle and Swanage with each other, and with a Park and Ride site at Norden station just to the north of Corfe Castle.^[1]

A new village hall opened in July 2010, achieved as a result of residents securing funding from various external sources.
