The rail plays two important roles: direct support of rolling loads and steering of the rolling stock. The rail must also fulfill three conditions: resistance, ride comfort and noise level reduction. In order to ensure the latter , the rails are regularly examined from every angle.

- Aluminothermic welding is used to ensure the continuity of the railway tracks when they have to be replaced. These welding operations avoid transitions that would represent a weak point of the tracks and thus affect ride comfort. (1/2)
