For over 100 years signalboxes were more common on railways than stations, goods sheds or engine sheds. Almost every station had at least one; most road level crossings were protected by one and all junctions were controlled by at least one. In the 1940s, there were around 10,000 signalboxes around the country, but today very few have survived owing to the vast reduction of the railways and the rapid progression of modernisation.
This handy new book is a fully revised second edition of the hugely popular abc Signalboxes. Now published in colour throughout, the text is illuminated by a fabulous set of illustrations and provides readers with a concise history of these much loved structures alongside comprehensive coverage of all surviving signalboxes.
