At ELECTRANS we are experts in providing integrated ATP solutions for tram and metro networks. Our journey for more than 45 years has allowed us to accumulate great knowledge, have a wide return on experience and invest in constant R&D through projects carried out around the world.
The experience has allowed us to see first-hand the great differences between a new construction project and the extensions to an existing network. In the latter case, closed systems, proprietary software and technological incompatibilities pose significant challenges as they severely limit viable options.
Our solution is the ATP CAS-E system, which allows automatic speed supervision and control to be carried out simply by means of an on-board processing unit and passive beacons located on the track, which do not require any type of connection not even for its power supply or relation to existing signalling systems.
The on-board unit makes it possible to monitor driving speed through speed maps for the entire track route, receive fixed telegrams from the beacons or establish temporary speed restrictions and define three braking curves with their respective configurable warnings and action levels in each case.
This architecture allows simple integration into existing networks, improves the cost-efficiency ratio and the possibility of future extensions of functionalities, such as protection of restrictive aspects of signals, route requests, priority management at traffic signalized junctions or rolling stock detection among others, thanks to the modularity of the system.
