Initially created to allow trains to cross borders without the need to change locomotive or driver, the European Rail Traffic Management System (ERTMS/ETCS) is now being adopted globally. Responding to an EU initiative, the system was developed by key partners in Europe’s rail and signalling industry (UNISIG).
As an active member of UNISIG, Bombardier is at the forefront in producing the system specifications, for example, with the Bombardier-developed Eurobalise transmission technology.
Major benefits of ERTMS include:
Bombardier leads the way in providing ERTMS technology as part of its INTERFLO range of mainline solutions. The INTERFLO 250, 450 and 550 are Bombardier's scalable European Rail Traffic Management Systems (ERTMS) mainline scalable solutions for Level 1, 2 and 3 respectively, suitable for secondary and regional lines and high speed and commuter lines.
ERTMS level 1
We are already supplying ERTMS Level 1 solutions in Europe and Asia
ERTMS Level 2
We were the first supplier to commission an ERTMS Level 2 system for commercial operation in Switzerland, 2002
ERTMS Level 3
We are implementing the moving block ERTMS Level 3 solution.
Ongoing projects include for major lines in the Algeria, Brazil, Chile, Morocco, the Netherlands, Poland, Spain, Sweden and Turkey.
Our product strategy is based on offering low life cycle cost solutions to our customers. We offer constant improvement in availability by utilizing well defined, proven hardware and software components and modules across our applications.
The INTERFLO 250 solution is an ERTMS/ETCS Level 1 signalling solution for main lines with SIL4 certification. This solution comprises all the sub-systems required, including the onboard and wayside Automatic Train Protection (ATP) equipment.
The INTERFLO 250 solution is commonly applied as an overlay to existing conventional lines, sometimes equipped with national ATP, providing higher levels of safety, but offering an economical migration and early experience with ERTMS Level 1 technology.
We have developed a range of Specific Transmission Modules (STMs) which can read signals from the legacy wayside ATP infrastructure and transfer it to the ATPC onboard equipment for execution. The overlay capacity of our systems enables shorter delivery times with minimum disruption to the existing service.
The INTERFLO 450 ERTMS/ETCS Level 2 signalling solution is for mainlines with SIL4 certification. This solution comprises all the sub-systems required, including onboard and wayside ERTMS Automatic Train Protection (ATP) equipment.
The INTERFLO 450 solution can be applied to new, dedicated high-speed lines offering high levels of safety and speeds up to 350 km/h, or as an overlay to existing conventional lines replacing the national ATP system or for mixed operation requiring Specific Transmission Modules (STM) functionality. The INTERFLO 450 solution goes a step further, being able to interface with GSM-R and with other railway communications standards such as GPRS and LTE. The need for wayside equipment such as light signals, is completely removed leading to a reduction in long-term maintenance costs.
The INTERFLO 550 wayside train control solution is flexible, modularized and specifically designed to provide the capacity, adaptability and cost-effectiveness needed for both low and high-density lines.
Its modular design concept enables us to customize the solution to particular preferences and supports future growth while consistently ensuring safe and efficient train operation.
The INTERFLO 550 solution goes a step further, being able to interface GSM-R but, GORS, LTE, and Tetra.
With the Level 3 Hybrid application, the INTERFLO 550 helps smooth upgrades of Level 2 lines that requires an increase its capacity without disrupting existing service. The hybrid solution still allows the use of the existing Level 2 equipment and the operation of non-equipped trains.
