Britain's Last Mechanical Signalling

Mechanical signalling has been on the way out since colour signalling was introduced in the 1920s. It was originally intended to replace all mechanical signalling by the millennium, however, numerous outposts remain on the national network. Network Rail aims to eliminate the last of its mechanical signalling and move control to a dozen railway operating centres, but its pace is limited by the cost. This book looks at the last mechanical signalling on the British railway network.
