Ansaldo STS also pioneered the high-speed railway transportation era by commissioning the very first high-speed signalling system for the first LGV in revenue service in 1981 in France (LGV Paris-Lyon). In 2005, Ansaldo STS set another landmark, by putting into service the first high-speed line running on an ERTMS level two signalling system (AV Rome-Naples, in Italy).

The most advanced railway networks and mass-transit operators can only rely on the most sophisticated, high-tech and safest components available. Ansaldo STS develops these at three world-leading factories located in Italy, France and the US.
