The 1867 Dolphinton [CR] line started from a junction which allowed trains from Carstairs station to join the branch. A box opened with the junction. The Dolphinton branch severed the south to east 1848 curve (out of use from around 1860) and a replacement curve was built from Strawfrank Junction to Dolphinton Junction in 1872.
The Dolphinton line closed in 1952 but the box remained in use due to the curve to Strawfrank.
The junction was renamed with a more appropriate name during electrification of the route. The box closed in 1972, replaced by a temporary box at Carstairs.
