INTERFLO ERTMS onboard components
Bombardier Transportation's products have been developed for the lowest possible life cycle costs. They are based on well proven and tested, durable modern components designed for minimum maintenance. The system components are also designed for efficient servicing in the field. Modules can be replaced quickly, without affecting traffic on the line.
Thousands of passenger trips per day are made on trains using equipment supplied by Bombardier Transportation, with a large number of train operators relying on our products, technology and solutions to run their services.
INTERFLO onboard components
As part of the INTERFLO system, EBI Cab onboard equipment supports the driver and continuously supervises the speed of the train.
The hardware components used for the EBI Cab onboard system are from the Bombardier MITRAC CC train control and management system, developed within Bombardier Transportation and used onboard large numbers of Bombardier Transportation built trains, providing us with wide experience of train characteristics of different rolling stock all over the world.
The onboard hardware components consist of a small number of fully encapsulated and EMC approved MITRAC CC computers and I/O units connected through an MVB field bus. They can be placed wherever they fit, a feature particularly valuable in retrofitting existing rolling stock to ERTMS. The modules can also be installed in streamlined cabinets for new rolling stock. Our system provides flexibility for every type and kind of rolling stock.
EBI Cab onboard equipment is an evolution of our EBI Cab onboard system which can be implemented in all application levels according to the ERTMS specifications.
For a smooth introduction of ERTMS/ETCS to a railway network, the EBI Cab onboard system also includes an interface for specific transmission modules (STM) which can be used on existing signalling systems. STMs are designed for reading and interpreting existing, non ERTMS/ETCS wayside automatic train protection (ATP) systems. This permits, for example, the smooth introduction of ERTMS/ETCS to the network in stages, as the old ATP equipment is removed.
When using STMs, the driver's panel and other onboard equipment can be used with different European signalling systems. This means the driver can receive information the same way on the panel regardless of the country the train is in.
The EBI Cab onboard driver's panel has a graphical colour display which shows continuous information on the maximum permitted train speed. The driver receives continuously updated information about approaching targets along the line and target speeds.
The EBI Cab onboard system warns the driver if the maximum permitted speed is exceeded and activates the brakes in the event of danger. The EBI Cab onboard system guarantees the highest possible level of safety and can monitor high-speed trains as well as regional, commuter and freight trains.
EBI Cab 2000 onboard train supervision in ERTMS Level 1 is based on the fixed block, distance-to-go principle. Trains are detected by track circuits or axle counters, and visual information is given to drivers from trackside optical signals. In some markets, other types of ATP systems may exist. EBI Cab onboard equipment is able to interface with these systems using a specific transmission module, STM. The information will be translated into ETCS/ERTMS format by the STM.
INTERFLO 250 ERTMS Level 1, can easily be upgraded to INTERFLO 450 ERTMS Level 2. This will enable the onboard equipment to use radio-based signalling on ERTMS Level 2 and regional ERTMS lines.
Information between the wayside and the onboard equipment is transmitted via radio. The information required for operating the train is displayed on the driver's panel. No optical signals are required along the line with the INTERFLO 450 solution, ERTMS Level 2.
We have vast experience in delivering train protection systems to many national railways, including the Spanish National Railways (RENFE) new high-speed lines.
The new high-speed trains will encompass a train control and communication system and a highly complex signalling system, supplied by Bombardier Transportation, which will enable them to operate in different safety environments: ERTMS Level 1 and Level 2, the existing Spanish system ASFA, EBI Cab 900 and LZB, whilst reaching speeds of up to 250 km/h.
