This 1897 signal box was on the east side of the line south of Carstairs, Float Viaduct and the Strawfrank Watertroughs. It controlled access to Grange Siding from which the Cairngryffe Quarry Tramway ran south west to the quarry. The siding was on the west side of the line and approached from the north.
The box closed in 1964.
Nothing remains but railway cottages, the Grange Cottages, to the south of the siding. The main line remains open.
