CBTC based ATC for Metro
In purchasing a CBTC solution, go with the experience of a proven leader. Hitachi Rail STS is applying its vast knowledge and experience in the industry to the development of advanced rail transit control systems that build upon traditional signalling with a new generation of innovative technology. Our Communications-Based Train Control (CBTC) solution offers enormous potential for the transit industry, both in ensuring safety and maximizing rail capacity.
In creating our CBTC solution, we developed and assembled an advanced set of best-in-class sub-systems that are unrivalled in their robust service pedigree and reliability while adhering to the IEEE 1474.1™ Standard for CBTC performance and Functional Requirements. When configured, they create a fully integrated and flexible platform that can deliver your business objectives across the board. Configuration to conform to emergent inter-operable standards in Europe is equally available and we are actively supporting industry standards initiatives to ensure best value and longest supportable service life for systems that we deliver.
There was no margin for second-best. When the city of Copenhagen, Denmark, set about building an innovative metro transit system in the new millennium, the planners in charge insisted on the highest industry standards, especially in terms of safety and reliability. So in selecting a vendor to develop and implement an advanced solution for their system's critical Automatic Train Control (ATC) technology, they chose the industry leader with over 150 years of experience, Hitachi Rail STS.
The Copenhagen Metro is the first fully automatic driverless transit system developed and implemented to meet stringent European CENELEC (European Committee for Electrotechnical Standardization) standards. Through this accomplishment, Hitachi Rail STS has provided a new and safer direction for the future of metro transit systems. In fact it has set the standard for others to follow.
Success breeds success. The success of the Copenhagen Driverless Metro is seen in the list of municipalities that are now building similar systems, including Rome, Milan, Thessaloniki and Brescia
Track Circuit-Based Automatic Train Control (ATC) profile-based transit, along with ATP, ATS and ATO subsystems and built-in train detection, enables driverless and semi-driverless operation for heavy and light rail transit. Proven, reliable technology in revenue service throughout the world provides a durable and efficient solution where systems based on radio communication of safety data are not favoured.
- Automatic Train Protection (ATP) ensures safe separation of trains
- Automatic Train Operation (ATO) vehicle and wayside components provide automatic stop and speed regulation.
- Supported by the underpinning safety assured by ATP, ATO delivers closer headway – more capacity
- Automatic Train Supervision (ATS) office system provides traffic coordination and route control
