The northern portals of the main London - Derby railway tunnels are almost baronial castellated structures on Red Hill. The original built in 1839 was asymmetrical with a tower on one side only (with rooms). The line was doubled in 1901 and another tunnel was made by the side. The original portal was copied but opposite hand so that the two are now a pair. (1) (3)
