The station opened on 18 June 1866 by the Peebles Railway. The station was situated south of the A72 and was accessed from a drive from the level crossing to the west. The station was called Thornilee but it was corrected to Thornielee in March 1872. There was no signal box but there was a small goods yard on the up side to the west. It consisted of a single siding accessed from the east with a loop. The station was never busy and closed to both passengers and goods traffic on 6 November 1950.[1][2]
