The Broadrigg Colliery railways connected to the North Monkland Railway close to Roughrigg Colliery Pit No 11. A branch, on the south side of the line and approached from the west, ran south east to a reversing spur by Roughrigg Colliery Pit No 3. By reversal Roughrigg Colliery Pit No 5 could be reached.
The Broadrigg Colliery railways also connected to the Slamannan Railway, not far to the south. The lines and mines were closed by 1910.
