The Cannock Mineral Railway was a railway company that built a line from Cannock to join the London and North Western Railway (LNWR) at Rugeley, in England. It was conceived and authorised as the Derbyshire, Staffordshire and Worcestershire Junction Railway, with the intention of connecting Dudley and Uttoxeter, but it was hopelessly undercapitalised and badly managed.
As finally built it was seven miles in length, and joined the South Staffordshire Railway (SSR) at Cannock. It was leased to, and then absorbed by the LNWR, and with the SSR it simply formed part of the LNWR network in the district, chiefly serving extractive industries.
It opened to passenger and goods traffic in 1859. Passenger traffic was discontinued in 1965, but was resumed in 1989 and is still (2022) in operation, with a typically half-hourly service operated by West Midlands Trains under the branding London Northwestern.
