For over 150 years Britain's railways have relied on a system of
semaphore signalling, but by 2020, all semaphore signals and lineside
signal boxes will be gone. A Contemporary Perspective on GWR Signalling
provides a unique record of the last operational mechanical signalling
and infrastructure on Britain's railway network, as it applied to the
former Great Western Railway (and lines owned jointly with other
companies). It also includes a comprehensive explanation of what
mechanical signalling is and how it works. Beautifully illustrated with
over 400 contemporary images and with detailed information from a
2003-2014 survey, this is an essential resource for anyone with an
interest in the traditional signalling systems of railways in Britain.
The book covers: Lineside signalling equipment - semaphore signals,
brackets and gantries, and other variations.Ways of working, from
Absolute Block to Track Circuit Block (TCB).Detailed coverage of the
signal boxes and infrastructure on Network Rail, including routes
