forces in motion

Mexico City/Munich. The railroad line Toluca–Mexico City is scheduled to become operational early in 2021. The special feature is the MAURER seismic protection system for two long viaducts. For this purpose, so-called guided cross-ties, the first absolutely earthquake-proof railroad bridge expansion joints, are installed at the ends of the individual bridge sections. Together with a complex system consisting of bearings, dampers and elastomeric spring isolators they ensure structural stability, function and safety for various load cases: from braking and acceleration forces in normal operation to the Maximum Considered Earthquake (MCE).
