A siding is reached by reversing from a spur off the southbound line of the loop at Lairg, south of the station. These oil sidings have seen irregular use with the flow from Grangemouth New Oil Terminal starting and ceasing several times. At present, 2018, the sidings are not used, oil travels by road.
