Prestressed concrete sleepers for track systems are increasingly replacing steel and wood sleepers. Companies are investing in modern production facilities to meet the demand.

High-speed rail lines traveling at more than 200 km/h and higher axle loads subject the roadbeds of railroad lines to enormous forces. Prestressed concrete sleepers for track systems therefore increasingly replace steel or wood sleepers in rail networks. They have a longer service life, require less maintenance and are more environmentally sound, since impregnation with coal-creosote is eliminated. To meet the rising demand of the industry and the public sector, construction materials suppliers and building contractors increasingly invest in precast plants, as, for example, the GIC Group at...
