A train journey from Bridgend to London

More than a hundred years ago great engineers conceived designed and built railways crossing the length and breadth if the British Isles. The basic principle has remained unchanged ever since; two parallel rails forming a continuous road between two points that vehicles with wheels designed to stay on these rails can move. One person can drive the train, conveying a thousand to their approximate destination; the thousand can read, eat, talk, and distract themselves by looking out of the window or type hopelessly on a laptop keyboard.
