Edgware, Highgate and London Railway

The Edgware, Highgate and London Railway was a railway in north London. The railway was a precursor of parts of London Underground's Northern Line and was, in the 1930s the core of an ambitious expansion plan for that line which was thwarted by the Second World War. Parts of the line were closed in the 1950s and have since been removed.
