This is what he says about his map being distinct and more useful
Beck dispensed with basic geographic realism. He simplified the network by showing it in lines that were as straight as possible, all horizontal, vertical, or at 45°, with regular curves between them. He also placed the stations at regular intervals – in the real world, distances between stations vary from a few hundred yards to many miles – and used special symbols to mark interchanges. Colour coding of lines, and marking stations with small tags, had been done before. His diagram expanded the very complicated central area, and made the long branch lines to Essex and Buckinghamshire look correspondingly much shorter.
