The British Railways Pre-Grouping Atlas and Gazetteer was first published by Ian Allan in 1958 but has not been revised since the fifth edition in 1967. For this new edition the cartography has been completely redrawn in a larger page size to make the mapping much clearer and easier to read. It has also been thoroughly corrected and for the first time will include lines not built at the time of the 1923 Grouping to show the entire historical railway network. The atlas also has a gazetteer listing abbreviations of the railway companies and an index listing tunnels, water troughs, principal summits, stations, goods and locomotive works, depots and junctions shown on the maps.
The ownership of each line is differentiated by colour coding, with enlarged sections of the most complicated centres, making this an essential work of reference for all those onterested in the history of Britain's railways, both the thousands of miles of railway lines that have now disappeared and the origins of today's network that still survives.
