The branch had a triangular junction with the main line to allow trains from Lanark to head west towards Carluke or east to Carstairs.

In 1974, the Lanark branch was included in the West Coast Main Line "Electric Scots" electrification project by British Rail.

There are no southbound or eastbound services, as the branch only has a northbound chord connecting it to the West Coast Main Line (WCML) at Lanark Junction.

There have been calls for the southbound chord to be reconnected to allow direct services from Lanark to Edinburgh,[6] but the route was subsequently re-used for housing.
