STM-ATB for ERTMS migration
Safe driving on ATB in ETCS environment
Maintaining safe driving during the transition to ERTMS
Transporters that switch to ERTMS are faced with a difficult task: trains must be able to continue to run safely on both ATB and ERTMS routes, without the entire fleet being converted in one go, costly and risky. STM-ATB offers a practical solution for this.
STM-ATB has been developed as on-board equipment that allows the existing Dutch ATB system to work together with an ETCS on-board system. The solution decodes ATB track signals, translates them into a maximum permitted speed and presents them to the operator via cab signalling. If the limit is exceeded, the system warns and intervenes automatically with a brake command via ETCS. By combining ATB-EG and ATB-Vv with ETCS functionality, trains can continue to run safely on ATB-equipped routes during the phased introduction of ERTMS. In this way, STM-ATB supports carriers, vehicle suppliers and infrastructure managers in a controlled transition to the new security system, while maintaining safety, availability and interoperability.
Practical and demonstrably safe
Phased ERTMS migration becomes practically feasible with STM-ATB. ICT InTraffic understands both legacy ATB and modern ETCS systems, and designs the solution with safety, certifiability and reliability in mind — so that working with an experienced partner reduces the implementation risk.
The advantages of STM-ATB
- Safe connection of ATB-EG and ATB-Vv to ETCS on-board systems
- Supports safe operation on ATP sections during the ERTMS transition
- SIL 3 safety-critical design according to relevant CENELEC standards
- Compact, robust and suitable for integration into a wide range of equipment
