The distance between the tracks can vary from 600 mm (narrow gauge) to 1676 mm (broad gauge), that depends on which country are you. In most of Europe (with exceptions of Ireland, former USSR republics, Finland, Spain and Portugal) the gauge is 1435 mm (the type of train has no relation with gauge). In USA, Canada and Mexico the gauge is also 1435 mm. In Asia, Turkey, Siria, Lebanon, Israel, Saudi Arabia, Irak, Iran, China and part of Vietnam, high speed lines in Japan and Taiwan have a 1435 mm gauge, the other countries have metre gauge (1050 or 1000 mm) or broad gauge (1676 mm in Pakistan, India and Bangladesh). In Africa most of them have metre gauge (1000 or 1067 mm), with exception of Gabon, Mauritanie, Maroc, Algeria, Tunis, Liberia and Egypt (1435 mm). In South America Venezuela, Uruguay, Paraguay, Peru and part of Argentina have a gauge of 1435 mm. Part of Chile and most of Argentina have 1676, part of Argentina (most in the North and Northwest), Bolivia, North of Chile, Ecuador and most of Brazil have 1000 mm gauge. Colombia has 914 mm gauge. Part of Brazil a gauge of 1600 mm. In Australia most lines in Victoria state and in South Australia have a gauge of 1600 mm, in Queensland of 1067 and in the others standard gauge. There is metre gauge too around Perth and in Tasmania. Of course, there are or there were several industrial or regional railways with diferent gauge in several countries, I was talking only of the national networks in those countries.
