A train with wheels an tracks improved characterised by using pulley wheels on which the bottom of the pulley throat is of a cross-section slightly less than a semi-circunference, the rail head being aproximately semi-circular in cross-section and of slightly less radius, forming the rail a roughly semi-circular cross-section channel between the web and skid, in which inclined wheels rest which have a peripheral or edge curvature also of semi-circular cross-section. <IMAGE>
