After the opening of the Stockton and Darlington Railway in 1825 to transport coal from the Witton Park Colliery to Newport on the River Tees, railways had been expanding across County Durham to provide coal mine owners with access to cheap economic transport. Bishop Auckland gained its first rail link in 1842, when the S&DR backed Bishop Auckland and Weardale Railway gained the powers via an Act of Parliament to build a railway line from the S&DR's station at via Bishop Auckland and Witton-le-Wear into Crook, County Durham. After the completion of Shildon Tunnel, the BA&WR erected a permanent station in the town which opened to freight on 8 November 1843, and passengers on 30 January 1843. All operations were sub-leased as agreed to the S&DR. The opening of Bishop Auckland created a new railway junction, with lines eventually progressing north to Crook and Weardale ; and south to via. However, there were still coal mines to the east of Bishop Auckland, and the substantial passenger traffic from Durham.
History
Developed by North Eastern Railway, they built a new terminus in Tenter Street, Bishop Auckland. The line to Durham opened to freight on 19 August 1856 and passengers on 1 April 1857. There were intermediate stations at, and, while a fourth station serving Brandon Colliery opened in 1861. However, the S&DR and NER quickly came to the agreement of development of a joint station at, and so rebuilt the existing former BA&WR station, with NER trains using it from December 1857.
Durham and ECML junction
Although there were three existing station within Durham, the NER choose to develop a new fourth station site on the current location, requiring a viaduct over North Road and a further viaduct over the River Browney immediately to the south. As Durham gained connections to along both the Deerness Valley Railway and the Lanchester Railway, the three lines connected at Deerness Valley Junction. In 1871 the NER developed a new line from Tursdale through Durham, and onwards north to Newcastle Central via Chester-le-Street. This soon became the main line between London and Newcastle, the current East Coast Main Line. The existing lines connected with the new mainline via Rellymill Junction.
Closure
Hunwick lost its freight service in 1958. Scheduled passenger services between Sunderland, Durham and Bishop Auckland ceased in May 1964, although in July 1964 a Durham Miners' Gala train used the line to pick up passengers. Freight services were ceased from Brancepeth, Willington and Brandon Collieries from 10 August 1964. The line remained in place until 1968, when contractors removed the residual track. Since closure of all three branchlines, the mainline between Rellymill Junction to Deerness Valley Junction has been incorporated into a realigned East Coast Main Line curve, eased to increase line speed.
Present
After lying derelict for over 25 years, of the former trackbed has been redeveloped by Durham County Council as the Brandon to Bishop Auckland rail trail. In January 2019, Campaign for Better Transport released a report identifying the line which was listed as Priority 2 for reopening. Priority 2 is for those lines which require further development or a change in circumstances.
