Eurailtest Performs Safety Tests on Flirt LEX For the New Leman Express Line

The services commissioned were carried out between December 2017 and July 2019 and comprised several phases in connection with qualification, integration and tests. The engineering work performed by the CIM began with qualification on the simulator of the complete ERTMS/KVB dual standard system with its Flirt LEX parameter settings. This stage consisted of checking that the safety equipment was properly installed on the basis of the manufacturer’s documents (and in relation to equipment supplier documentation). Once test rig qualification operations were completed, the CIM moved on to the next stage, in other words qualification of the trainset itself. The safety equipment and its specific settings had to be submitted to dynamic tests, and to SAM S 702 and ERTMS Level 1, L1-LS and KVB tests. The aim of all these operations was to ensure that the equipment was properly installed and that the interfaces between Flirt LEX rolling stock and the dual standard, ATESS and radio systems were duly in place (static and dynamic tests on single and multiple unit trainsets [UM2]). The necessary organisational arrangements were entrusted to AEF. Once qualification and integration tests had been satisfactorily performed, the CIM then undertook the safety operations needed to provide the proof needed for obtaining full market approval (AMM, formerly AMEC = revenue service authority). All these operations were conducted on the basic and specific parts of the dual standard equipment. For the specific parts, the CIM proceeded via analysis of the safety studies performed by STADLER and required for the rolling stock safety case application.

Flirt LEX was given full market approval (AMM) on 15 October 2019 and is scheduled to be commissioned on the Leman Express line on 15 December 2019.
