Tunnels of Nottingham

Many of the tunnels of Nottingham were built by three railway companies in and around Nottingham, England because their lines crossed substantial hills. The companies were the Great Northern Railway (GNR), the Great Central Railway (GCR), and the Nottingham Suburban Railway. The LNWR built a station in Nottingham on Manvers Street with its own lines and sidings running off the GNR; whilst it had no tunnel on its short route, it did have a large underground storage depot under the station site, and this is still there. The Park Tunnel was built for more fanciful reasons. Nottingham is home to many underground structures but only those built for transport are mentioned here.
