S&C renewals

Switches and crossing are the critical points in any railway network where tracks separate, cross each other and reconnect. Ever increasing speeds and wheel loads continue to place additional stress on these vital components of railway infrastructure. As such they demand constant attention and intensive maintenance.

LEONHARD WEISS is your specialist for renewal, maintenance and repair of switches ranging from simple industrial yard switches to complex high-speed switches. We excel in all track types, whether ballasted or slab based. Our modern high-performance cranes enable us to install large prefabricated switch parts of the highest quality without affecting normal railway traffic.
