Great Railway Journeys: London to Oxford and London to Cambridge is the fourth in Roger Mason’s Great Railway Journeys series. The others have been two routes from London to Birmingham, and also London to Sheffield. It is a fascinating record of things that can be seen from the trains running from London to the two great university cities.The London to Oxford line includes Windsor Castle and the Didcot Railway Centre, which is a living museum of the Great Western Railway. A particularly interesting chapter tells how the author of a world famous book left the manuscript in a station café. He had not kept a copy so he went home and wrote it again.The London to Cambridge line explains the story of a town with a rich archaeological heritage, including some intriguing cave drawings. There are also the church with links to a seventh century place of worship and story of the world’s first garden city.
