CER position on the practical arrangement on ERTMS track side approval

CER acknowledges the last version of the working paper v0.6 on practical arrangements for trackside approval published in March 2017. We welcome the progress made, there is now a foundation that should allow to finalise, after learning cases, a truly efficient and effective process for approval and authorisation and to enhance interoperability. There are 3 main unsolved issues that will have to be refined in the light of learning cases.
