Abstract (en)
[origin: EP2730699A1] The method involves resting sleepers (14) of a railway track system on a ballast bedding (12). Rails (16) are placed on the sleepers. Foaming agent i.e. carbon dioxide, is brought into contact with the ballast bedding during covering the rails. The ballast bedding is limited in a threshold shed (18) by two sleepers. The ballast bedding is provided with a top face (26) pointing against gravitational force direction, so that the top face of the ballast bedding positions on height above an underside (36) of the sleepers in gravitational force direction.
