Resolving the remaining DMI issues before the adoption of next ERTMS specification release

Resolving the remaining DMI issues before the adoption of next ERTMS specification release

Wednesday, 6 January 2016

In the letter sent mid 2015 and in the RISC workshops, CER alerted the Agency and the European Commission on the need to ensure the appropriate resolution of some change requests, namely the CR1249 “bundle”, which would affect railway operations.

Since then, technical solution have been investigated by ERA and technical bodies and a validation of the possible solutions has been performed with several European drivers on an ERTMS simulator. However, the solution actually part of B3R2 is not in line with the conclusion of the validation exercise. The recommended solution would lead to issues for the driver or in general train operations. Some last improvements are needed.
