Geschwindigkeitsüberwachung Neigetechnik

The train protection system Geschwindigkeitsüberwachung Neigetechnik (German, translated "Speed Control for Tilting Technology") (abbr. GNT) enables to rise the speed of tilting trains until 30% above the limits for conventional trains. It is installed on numerous lines in Germany along with the traditional Punktförmige Zugbeeinflussung (PZB) intermittent signalling system.
