Device for the substitution of the rails of railway tracks
First Claim
1. Device for the continuous substitution of the rails of railway tracks, comprising:
- a train composed of a welding vehicle and a heating vehicle, both running on old rails with said welding vehicle running before said heating vehicle, and an assembly vehicle running on new rails;
(A) wherein said welding vehicle includes;
(1) means for positioning the new rails to be welded and previously brought to the site between the old rails,(2) at least one welding unit for welding the adjacent ends of the new rails which pass below the axles of said welding vehicle, and(3) a grinding unit,wherein said means for positioning said at least one welding unit and said grinding unit are installed between leading and rear bogies of the welding vehicle;
(B) wherein said heating vehicle includes;
(1) at least one heating tunnel for each new rail, equipped with a facility for induction heating, said tunnel being traversed continuously be the new rail during the advance of the train in order to neutralize said new rail, said heating tunnel being located between the old rails and below the body of the heating vehicle, the new rails passing below the axles and between the wheels of said heating vehicle;
(2) means for measuring and controlling the temperature of the new rails;
(3) means for gripping the new rails to introduce them into said tunnel;
(4) stations for releasing the old rails from sleepers, said stations being installed between bogies of said heating vehicle; and
(5) means for guiding the old rails that are detached; and
(C) wherein said assembly vehicle running on the new rails laid upon the sleepers includes;
(1) means for guiding and for laying the new rails on the sleepers, said means being disposed at a front end of said assembly vehicle, and(2) working stations for fastening to the sleepers the new rails brought to the desired temperature.

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.
