Periodic Reporting for period 2 - PERFORMINGRAIL (PERformance-based Formal modelling and Optimal tRaffic Management for movING-block RAILway signalling)

Podsumowanie kontekstu i ogólnych celów projektu

Moving Block System (MBS) is the state-of-the-art train control system for railway operation control. The main principle of MBS is to improve the train localisation precision through advanced train localisation technologies, thus trains could be positioned with the accuracy of meters rather than blocks which is about 1km long each divided on railway line. With such accuracy of train localisation, the safe headway of trains between each other could be significantly reduced, thus the railway capacity could be largely improved through MBS.

MBS has been developed successfully and validated for metros all over the world, however due to the network and operation complexity, MBS is still under development worldwide for mainline railways.
To support the development of MBS across Europe and also the activities in Shift2Rail Innovation Programme 2, the EU Shift2Rail project PERFORMINGRAIL implemented a holistic system approach to address the open challenges for the Moving Block concept in terms of safe operational principles and specifications, reliable TIM technologies, high-accuracy train localisation and optimised moving-block traffic management algorithms.

The main objectives of PERFORMINGRAIL are to contribute with:

• Enhanced railways Fault Detection and Exclusion algorithms for addressing local feared events;
• Data fusion algorithms suitable for railway safe applications;
• EGNSS monitoring techniques based on carrier phase measurement and multi-frequency technology;
• To help promote the use of formal methods as a means to check safety of advanced railway operation (in accordance with IP2 TD2.7); and
• To provide Independent Assessment Report on the proposed technologies and solutions.
