This junction on the North British Railway's Blantyre branch gave access to Auchinraith Colliery Pits Nos 1 and 2. To the east was Birdsfield Siding and the connection to the main NBR Hamilton branch at Blantyre Junction [NBR].
The colliery was already served by the Hamilton and Strathaven Railway, the line from Auchinraith Junction curving east, north and then west to join the existing Caledonian Railway line.
Another Auchinraith Junction existed on the Hamilton and Strathaven Railway on a triangle of lines where the curves from Strathaven Junction and Blantyre Junction [CR] met.
