allow the implementation of ATO system affecting as less as possible the ETCS performance
and the underlying signalling system in case of existing ones.
• Clear migration facilities and plans. This is needed to define realistic planning and deployment
of such a complex system. Equipment to be provided by the suppliers must also facilitate
step-by-step migration strategies.
• Conformance Testing: Standardization of testing seems to be one of the most important
topic to be defined in order to meet the real interoperability of ATO system.
• Railway Sector Commitment is needed mostly to facilitate the co-ordination of planning
and deployment affecting the trains, the trackside signalling, and the trackside-train
communications.
