NEHL - Hylton Colliery was sunk on the site of a steel works, previously a small shipbuilding yard in the 1850s. It had began sinking in 1899, and were already on strike in 1900 given guaranteed conditions of no night work. Upon opening though the complex was vast, incorporating dozens of sidings along the old railway from Washington to Monkwearmouth. By the 1920s nearly 2,000 people worked here providing the spine of employment for the Castletown area and adding to an already dense supply chain on Wearside.

The pitmen had their own cricket and football clubs, with various players ending up playing professionally. The pit was added to the NCB portfolio during nationalisation but was closed in 1979. 440 people were employed at closure, and claims were made that it was losing around £3m a year by the end.
