ABSTRACT
Rails support and guide the wheels of the train vehicles. Their profile has been the object of continuous improvement since the appearance of railways.
Fig. 10.1. Grooved rail
Of the first rail profiles, the only one surviving to this day is the grooved rail (Fig 10.1), which is still in use along tracks where the rail top and the pavement surface are at the same level. These include tracks of tramway lines, in level crossings and in port facilities.
