Barring isolated systems (mines, logging) all track should be two meter gauge (78-3/4"). Although the measuring system of our neighbors across the Channel is not widely esteemed here, what we choose here in Britain will of course be widely copied throughout the World. Such a gauge would provide for the future, "future-proof", the Global system of track, allowing wider loads, greater stability for passengers, etc., it being readily apparent that rail is the future of all long distance travel.
