At Castlehill Junction, immediately east of Ardrossan Town, the Ardrossan and Johnstone Railway was met by the west fork of the Largs Branch (Glasgow and South Western Railway). The box was located to the north of the junction and opened with the Largs branch in 1878.
The location was complicated by loops on the line from Holm Junction to the east, the division of the lines running west to Ardrossan Town splitting into passenger lines, goods lines and carriage sidings. Further lines were associated with Ardrossan Shed [GSW] [2nd] which was within the triangle of lines here. A turntable to the east was approached from the junction, convenient for turning locomotives which terminated in Ardrossan.
The Castlehill Junction to Holm Junction curve closed in 1969 and the box closed.
The original line remains open, now a single track electrified line.
