This signal box was a little way east Hamilton Central. It controlled access to Silverton Colliery, on the west side of the line, and Barncluith Colliery, on the east side. The box was between the approach to Silverton and the main line, opposite the approach to Barncluith. The collieries were approached from the north west.
The box closed in 1905.
Barncluith Viaduct and Barncluith Tunnel are to the south east.
