Conisbrough Tunnel East Portal

The Conisbrough Tunnel East Portal is a railway tunnel portal built in 1849 for the South Yorkshire, Doncaster and Goole Railway Company, with engineering by Charles Bartholomew of the River Don Company. It features gritstone voussoirs and rock-faced sandstone walling, with quoined buttresses flanking a horseshoe arch that has rustication below the impost band and a roll-moulded hoodmould. A roll-moulded cornice projects over the buttresses, and the blocking course steps up at the center. The railway line was opened on 10th November 1849, connecting the Midland and Great Northern networks. After 1864, it became part of the Manchester, Sheffield and Lincolnshire Railway, which was renamed the Great Central Railway in 1897. The east portal is linked by a 200-meter brick-lined tunnel to the west portal. Details about the new line were discussed in the Doncaster, Nottingham and Lincoln Gazette on 9th November 1849.
