Tracks: A Journey Through Metro-Land tells the story of Metro-land and the development of suburbia that grew alongside the Metropolitan Railway. Originally the brainchild of eminent Victorians, the Metropolitan grew to become the queen of underground lines, eventually expanding to a point some fifty miles outside London. Author Kevin J. Last describes how the concept of Metro-land was an aspiration for several levels of society, promising a better lifestyle well away from the deprivations of wartime. The idea that the working man could live comfortably outside the 'smoke' in individually designed houses would mean that he could also thrive at work, largely due to the regular service offered by the new railway. This was quite exceptional in that, while nominally an underground line, most of the Met's route was above ground and, in length, went far beyond other similar lines, far out into the Buckinghamshire countryside. Not marked on any map, Metro-land is as much a concept of the mind as a real place.
