Test your Trackside: Test Eurobalise contentTest RBC configurationTest your Onboard: Test GSM-R quality and availabilityVerify TSI compliance



Mandatory: All ERTMS projects need onsite testingTIME is criticalExpensive: Requires a test train equipped with ERTMS On Board Unit (OBU)A train with a SIL4 OBU is very expensiveFitted trains are a scarce resourceDesign: ERTMS OBU are not designed with testing in mindComplicated: GSM-R is often an issue and hard to diagnose with SIL4 OBUs

ERTMS onsite testing: the issues



Time: Enables testing within a reasonable timeframe, when no other solution existsCost-effectiveness: Onsite PRE-testing reduces the total costsEasy integration: No heavy homologation process / fits all trainsImmediate benefit: Diagnosis of test errors root cause during test journey (onboard and trackside)The solution: TestOBU.SIL0
