The line from Stanhope to Annfield Plain and from Medomsley to Annfield Plain, was opened in 1834 and later that year on to South Shields. The railway's engineer was Thomas Elliot Harrison who was to go on and play a very prominent part in the formation of the North Eastern Railway. 
In 1841 the company became insolvent and was incorporated into the Pontop and South Shields Railway. The west end of the line was sold to the Derwent Iron Co. This section was later sold to the Wear and Derwent Junction Railway
