In addition to the classical turnout products, voestalpine VAE also supplies special components like rail expansion joints in order to lay tracks across civil engineering structures (large bridges or viaducts). These constructions change their length because of external influences like traffic load, temperature and wind. Occasionally, these loads lead to rotations of the end span in the abutment connection.
Special trackwork components like rail expansion joints are used to securely bridge these length variations and, if required, accomodate end span rotations.
Furthermore, the voestalpine VAE Group develops and produces Vignol turnouts, crossovers, slips, diamond crossings and complete layouts, etc. in accordance with international standards or special customer requirements for all available rail profiles and required gauges.
