Over the years Ansaldo STS has been designing and developing products which have made it the leader in the segment of Signalling systems and railway transport and urban rail transport.

Optimizing Traffic Planner™

The OTP is an innovative railway traffic and operation management system which allows, in real time, for the redirection of traffic in order to increase the speed of circulation and optimise the movement of vehicles, by identifying the shortest and more efficient routes for the trains the circulation of which is expected in a certain period of time. The OTP system allows to considerably increase the network capacity, while reducing operating expenses.

ATC (Automatic Train Control) and ATP (Automatic Train Protection) systems

These are automatic train control systems in line with the ERTMS (European Rail Traffic Management System) standards, allow for the control of the safety of the train traffic on the railway, as well as ensure the identification of their position, keeping a safe distance and compliance with speed limits on a continuous basis. The ATC system also includes the driverless function, with different levels of automation. The systems which adopt the ERTMS standards make it possible for the trains to run on the entire European interoperable network without being required to change the engine crew or the rolling stock at the borders, to increase the safety of the national and international traffic and to improve the management of passenger and freight traffic. Ansaldo STS applies the ERTMS standard to the Signalling systems for the High Speed lines in Italy, to the LGV Est line in France, to the Madrid-Lleida line in Spain and to the Saarbrücken-Mannheim line in Germany, as well as to the Signalling systems for the Main lines in Italy, China, India, South Korea, Romania, Greece, Czech Republic, Turkey, Libya, etc.

CBTC – Communications Based Traffic Control

Ansaldo STS is developing the CBTC, which, in line with the international standards, bases the urban railway traffic control activities on Radio communications, in order to allow for the full interoperability on the metrolines between different system/technological operators in the case of maintenance or expansion of existing lines, The control systems installed on board calculate the position of the vehicle and adjust its movement to the authorised limits, Thanks to the communications between the control systems placed in the adjacent area, at the interlocking points and on board, it is possible to safely manage the headways of vehicles and the capacity of the line, additional advantages relate to:
  • the complete systems for central control rooms, on board and round that can be of a "stand alone" type or can be integrated with the existing systems;
  • optimisation of the headways of vehicles, only 60 seconds (introduction of the concept of “moving block”);
  • reduction or elimination of the requirement for track circuits or any other devices to calculate the position of the trains.

Ansaldo STS has already installed this technology on line 3 of the Paris metro, on line 1 of the Chinese metro of Shenyang and Chengdu, while other systems are being designed and, in some cases, are being installed such as the Ankara metro, the Taipei metro and the Copenhagen metro (the last two projects will manage the driverless mode).

Wayside platform

Since the late nineties, Ansaldo STS has implemented the requirements for the "open" platform on standard protocols, such as: lines TVM Lyon and Marseille, ERTMS lines Rome-Naples, Turin-Milan, Milan-Bologna-Zheng Xi, Madrid-Lleida, Cambrian, Poříčany - Kolin, Haparandabanan lines CBTC in Chengdu, Shenyang, Ankara Metro and conventional lines Turin-Padua.

Ansaldo STS has implemented the platform that WSP Wayside (Wayside Standard Platform) able to manage with a reduced number of basic components, a higher number of bodies square and train connections to integrate into one central place security features, diagnostics and control of movement appropriate to represent the best response to the market demands increasingly sophisticated rail and metro.
