D2.2 MOVINGRAIL - Moving Block Signalling System Test Methods

The aim of this deliverable is to outline an architecture and testing routines for moving block signalling systems that builds upon D2.1 and other relevant sources. This necessitates the identification of the differences between ETCS-L2 and moving block systems at architecture level, and then of the gap between the established testing procedures for ETCS-L2 and the requirements that have been identified for testing of moving block signalling systems.

The distinguishing characteristic of ETCS-L3, which can be defined with virtual fixed blocks or as a full moving block system, is the fact that train detection no longer relies on trackside equipment. Instead, the safety-critical task of determining whether a section of track is occupied is performed by the on-board computer and the Radio Block Centre (RBC). The integrity of trains, i.e. that there are no loose carriages or wagons, must be verified by train-based rather than trackside systems. This is especially important as trains run closer together..

The document is divided into two parts. Part A presents the modular testing architecture for moving block systems, including the required components and interfaces.  Part B uses the knowledge acquired from Part A and MOVINGRAIL D2.1 to present approaches for automated testing and to remove the current technical limitations for testing moving block systems. Strategy and automation approaches to minimise moving block on-site testing are identified.

The deliverable is pending approval from the Shift2Rail Joint Undertaking (JU).


The project will bring forward innovative concepts of “moving-block” railway traffic operations by (1) advancing testing methods for ETCS Level 3 and (2) Analysing Virtual Coupling which will lead to convoys of automated trains under cooperative adaptive control.
