More and more cities and local authorities launch development projects for certain underground or fast tram networks. Most of these projects are based on the use of innovative signalling and control systems which are secure for passengers. At present, CBTC signalling solutions are among the most used ones at the international level and, besides the efficiency and the safety, these solutions facilitate the optimisation of a transport system for the entire life cycle.
Signalling is the milestone of the railway system; under the circumstance of the conventional transport, the signalling systems allow the communication between infrastructure and trains, thus guaranteeing the overall cohesion of the system. The implementation of a strong general vision on the signalling system is a compulsory requirement in the current fragmented market of the railway transport which involves infrastructure managers, railway operators and third parties such as maintenance service providers, car owners, service providers and entities in the field of public procurement.
The CBTC signalling and control system for the rolling stock, a technology which belongs to the company Thales, represents an entire control system based on telecommunications.
Thales’s portfolio includes the first ETCS Level 1 project in commercial operation on the Sofia-Plovdiv-Burgas line in Bulgaria, ever since 2001, the first ETCS Level 2 project in commercial operation on the Jüterborg-Halle- Leipzig line in Germany, ever since 2005, as well as many others.
The company Thales is also present in the urban transport sector, being among the most important suppliers of advanced train signalling and control systems based on CBTC for the urban railway network. Thales systems allow to operators the optimisation of the capital investment (civil engineering, trains), flexibility in managing transport capacities (in the short and long run) but also the reduction of operating costs (energy, staff, and maintenance).
The SelTrac CBTC solution is present on 30 of the greatest and most crowded urban transport networks, among which we can mention Santiago de Chile, New York, Vancouver, London, Paris, Dubai, Hong Kong, Shanghai or Beijing.
The SelTrac solution perfectly adapts to different underground, tram, suburban train or automatic commuter train systems. A CBTC system is profitable and at the same time a sustainable investment and its performances allow the optimisation of passenger transport flows, as well as the reduction of the carbon footprint.
With a constant pressure to reduce operating costs, but also with the need for the quick improvement of the urban railway transport system, a series of operators prefer the flexibility ensured by the communications-based train control system.
Answering to the need for modern signalling systems, the SelTrac CBTC solution offers the opportunity of increasing the performance and the safety, as well as the cost reduction during the entire life cycle of the system.
