Don't know the exact year the school was built. I would assume there would be some colliery rows built when the colliery was due to start production. The Durham Mining Museum does not have a year against when the colliery was opened but it does have 1982 as the first year coal was output. The First Edition of the OS map of the Cambois area held on the National Library of Scotland is 1859 (published 1865) and there is no colliery or houses. The Second Edition - 1896 (published 1898) shows the colliery, many pit rows and the school etc.
The Tanfield Railway is a Industrial railway that runs with Industrial locomotives from the coal board and other Industrys. Many Locomotives From the northumberland coal field have been saved thanks to this railway and the hard working voulenteers to keep them going.
The Railway Really Catches the feel of long lost past, that was once so common.
