Group companies provide traffi c management, train control, production of signalling systems and maintenance services, all aiming to achieve lasting effi ciency and safety for both clients and end-users.
The Transportation Solutions Unit designs and produces integrated transport systems, i.e. it studies. designs and plans the integration of the design and construction of the technological elements that make up the transport system, including equipment, signalling, power supply, telecommunications and rolling-stock (whether for railway or metro trains), as well as any other technical items that, together with the foregoing, constitute an integrated transport system
The history of Ansaldo STS is characterised by the professionalism and passion of the various generations of people dealing with the evolution of new signalling technologies and with the solutions to be adopted in the transportation systems. The expertise of senior staff (men and women alike) is combined with the enthusiasm and creativity of young engineers, regardless of the economic situation, and the capital structure of the company. To innovate is a constant principle, in order to both improve what is already known and applied in real terms, and satisfy the needs of the customer and develop new solutions for the benefi t of the life of the individual user.
