the station had two platforms, each with a wooden waiting room and a ticket office built over the tracks alongside the road bridge. unlike other contemporary stations that were built on the castle eden branch, the station never had any goods facilities. a signal box had been built on the east side of the tracks, just south of the road bridge, when the castle eden branch first opened in 1877. originally called 'castle eden north junction', it was renamed 'wellfield' when the station opened and, in 1910, was replaced by a new signal box at the northern end of the southbound (eastern) platform. the signal box was unusual in that it overhung the platform (due to the restricted width of the site) but it outlived the station, not closing until 1979.
