Abstract
The new rails to be laid are heated continuously in order to be neutralized. For this purpose, they are raised and exposed to a source of heat in the form of two heating tunnels which are mounted on a vehicle running in a continuous manner on the old rails. Each heating tunnel is traversed by a stretch of new rail. Simultaneously, the old rails are detached from the sleepers, and, after the passage of the vehicle, are deposited along the track or are cleared away. The heating vehicle is followed by an assembly vehicle by means of which the new rails, brought to and maintained at the temperature of neutralization, are laid continuously on the sleepers and are fastened thereto. In front of the heating vehicle, there is provided, on the old track, a welding vehicle for welding the new rails.
