- System, integration, validation and safety tests. HOST (simulated environment) and TARGET (actual lab environment) integration tests.
- These are carried out on the most critical systems of the CBTC, which are ATP (Automatic Train Protection) and ATO (Automatic Train Operation). In not-so-critical systems, such as LTMS (Locomotive Train Management System) and DMI (Driver Machine Interface), support functions are performed through code modifications so that tests are passed eventually.
DETAILS OF THE PROJECT
The execution of the CBTC project has entailed the implementation of state-of-the-art traffic control and subway automation technologies, as well as the latest techniques in digital radio transmission. Train controlling based on CBTC communication is the solution for every kind of public transportation and suburban railway, and it’s already being implemented in the major cities of the world.
The Communication Based Train Control system (CBTC) is an automated and continuous monitoring process, based on smart communication between trains and the control centre, that enables monitoring and management of the line’s capacity, thus allowing more trains running at higher speeds in a shorter period of time safely
Each train transmits every few seconds its exact location to the control station. Having track of every train, the centre calculates in real time the safe distance each train is authorized to travel. This way, trains run at higher frequency not requiring lineside signalling
