The Mission

Ansaldo STS designs, realizes and manages Transport Systems by addressing the interfaces and the integration of the technological works that are parts of system: signaling, equipment, power supply, telecommunications and vehicles (whether they are rail or metropolitan) as well as any other technological works that together constitute an integrated transport system. The final product, whether it be a railroad line or a metro line, is delivered to the Customers also as  turnkey solution. However, the Company can offer its signaling skills and transport solutions also distinctly, taking into account the specific needs of the customer.

Ansaldo STS considers the social, economic, logistics, architectural, environmental and structural context of each project it handles, planning,designing and building signaling and railway and mass transit systems that provide the best possible combination of safety, efficiency and return on investment.

Among the major projects carried out by Ansaldo STS within the Transport Solutions, we note References

Over the years, its development of products and solutions - Development and Engineering - has carried Ansaldo STS to a leadership position in the Signaling Systems and Railway and Mass Transit Sectors.

OTP - Optimizing Traffic PlannerTM

OTP is an innovative traffic management and railway handling system that redirects traffic in real time to increase speed and optimize vehicle movement, identifying the shortest and most efficient paths for trains. The OTP system can substantially increase network capacity, reducing operating costs at the same time.

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

These are automatic train speed control systems in line with ERTMS (European Rail Traffic Management System) standards. They enable operators to control the safe movement of trains on railway lines, continuously monitoring their position, maintaining safe distances and compliance with speed limits.

The ATC system also includes a driverless function with various degrees of automation. Over the years, this system’s specifications evolves and in addition to being a company taking part in defining new specifications, ASTS adapts all of its systems in keeping with the European standard.

CBTC – Communication Based Train Control

CBTC is a two-way, radio-based train distancing communications system between wayside and vehicle. It is in line with international standards (IEEE 1474.1.2.3) and offers utmost operating flexibility and complete interoperability on metro lines managed by different systems/technology operators. The control systems installed on board calculate the vehicle’s position and adapt the movement of the vehicles within the authorized limits (MAL = Movement Authority Limit). Each vehicle’s position is updated and reported continuously to the wayside Area Controller. The Area Controller can update each vehicle’s MAL, knowing the position of the previous vehicle going in the same direction. This tool makes it possible to set a “moving block”, which safely and significantly shortens the headway between two consecutive trains on the same track, increasing the transportation system’s overall capacity. Communication between the control systems in the adjacent interlocking areas, in rail yards and on board, allows for a safe time management between the vehicles headway and the line capacity.

Wayside platform

Ansaldo STS has implemented the interlocking platform known as WSP (Wayside Standard Platform), capable of managing a greater number of trackside equipment using a smaller number of basic components and integrating safety, diagnostics and traffic management functions in one single control station, poised to become the best response to the increasingly sophisticated demands of the railway and metro market.

ASTS also adapts its interfacing with the yard using new generation equipment and components.

TRAMWAVE®

This is a power system for trams that uses an embedded ground-level power supply which only energizes the part of the line being used by a tram. The system enables the protection of historic city centers,as it eliminates conventional overhead electric lines.

The concept behind this innovative tram system and the excellent results achieved in the wake of testing have generated enormous interest among urban planners in countries looking for safe, ecological and low-environmental impact public transit solutions.

Satellite signaling

For the first time in railway history, Ansaldo STS has enabled the satellites use to manage safe train travel. In March 2012, Ansaldo STS signed the 3InSat contract with the ESA (European Space Agency) to develop and validate new safe geo-localization and satellite telecommunications platforms to be used for ERTMSETCS railway signaling systems. Ansaldo STS is the head of an industrial consortium that includes the participation of, inter alia, RFI, DB-Nets and DLR (Germany’s space agency), which, together with ASI (Italy’s space agency)are the greatest contributors to the European satellite navigation system, GALILEO.

Ansaldo STS’s solution constitutes a technological innovation of global importance. It will use geolocalization satellite technology instead of conventional train localization systems, which require electronic devices installed along the railway line, thereby reducing costs and environmental impact.

In order to maintain its leadership position in the ERTMS satellite technology sector and to extend the existing functionalities, Ansaldo STS launched the following projects:

  • the “ERTMS on Satellite – Enabling Application and Validation” project financed by the GSA in 2015;
  • the “Satellite Technology for Advanced Railway Signaling” project financed by the GSA (European Global Navigation Satellite System Agency) launched in 2016;
  • the “Railway High Integrity Navigation Overlay System” project which was launched by the GSA in 2016. Furthermore, Ansaldo STS is party to a contract for the provision of a signaling system for freight traffic that positions rolling stock using the satellite technology, for the customer Roy Hill. The line was activated in both IETO mode and full LDS mode during 2016.

TCCS - Train Conformity Check System

TCCS is a multi-functional railway portal that automatically detects irregular conditions that affect rolling stock in transit. It is one of the company’s key projects thanks to its cutting edge technology. Thanks to its sensors, the portal controls passing trains at cruise speed and overlaps the visible form, laser and infrared to detect:

  • the composition of the train and models of component vehicles;
  • overheated parts of the train and fire risk;
  • abnormal load;
  • shape compatibility.

TCCS ensures higher safety standards for the railway system, reducing the risk of accidents.
