Method for renewing the rails of a railway line with new long rails, and associated work train

摘要

The invention relates to a method for renewing old rails (21) of a railway line (20), in which during a first phase (A), new long rails (22) are unloaded along the railway line (20 ) from a transport trainset (120) of a work train (100) traveling in a first direction of travel (F1), characterized in that during a second phase (B) the work train travels in a second direction of travel circulation (F1) opposite to the first direction of circulation (F1), the new long rails (22) being laid then fixed on a fixed structure (23) of the railway track (20) during the second phase (B).
