The original powers for the Leen Valley Extension Line included a branch to the colliery at Langwith, north of the LD&ECR, but in October 1895 the GNR arranged to join the LD&ECR east of Langwith station instead, forming a slightly shorter route, and giving a direct run towards both Chesterfield and the Beighton line; there was a branch to the colliery off that line, with running powers there over the section of the LD&ECR; that company obtained reciprocal running powers to Shirebrook colliery.
