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. In his previous book, author Allen Jackson
covered the GWR lines; here, he continues his journey by providing a
pictorial record of the last operational signalling and infrastructure
on Britain's railway network, as it applied to the former London,
Midland and Scottish Railway (and lines owned jointly with other
companies). This second volume covers the routes of the following
companies: London & North Western Railway, Caledonian Railway and
Highland Railway.
