The latest editions of the London Railway Atlas with detailed mapping showing every railway line and platform, past and present, and detailed historical information about opening closing dates, name changes, ownership etc, have proved popular but the large page size means that the book is not handy to carry with you when travelling on the capital`s railway system. This `abc` edition of the atlas is a pocket size version, with the maps redrawn to a smaller scale. Although, for clarity it does not include all the historical information in the large format atlas, it shows all the railway lines in London, overground and underground, with closed lines clearly differentiated from the current network, with a complete gazetteer of all current station names.
