The station buildings were designed by Murdoch Paterson and it opened on 28 July 1874[5] and on that date the Highland Railway absorbed the S&CR and operated the newly completed line from Helmsdale to Thurso and Wick.

A wrought-iron turntable of 45 feet (14 m) diameter built by the Railway Steel and Plant Company of Manchester was installed at the station.

Following the introduction of Class 156 diesel multiple units on the line, trains were always composed of two trainsets (four cars) and at Georgemas, these would split in half with the front portion heading to Wick, the rear to Thurso.

An easement to the National Routeing Guide allows passengers for Wick to stay on the train between Georgemas Junction and Thurso, which would otherwise technically be off-route.

[9] Georgemas Junction station has been used for freight services that transport containers on to lorries which are taken by road to Wick and Thurso, as well as by ferry to Orkney.

In the early 2000s, EWS operated a freight train for Safeway supermarket, running containers from Mossend to be unloaded at Georgemas.
