The European Commission has awarded Ineco the contract to undertake a study entitled Support to the European Commission on the deployment of ERTMS on Core and Comprehensive Networks: On-Board and Infrastructure deployment strategies. Ineco is heading up this job in conjunction with the consulting firm PWC with the aim of facilitating the deployment of the ERTMS system in different European fleets. To carry it out, three specific networks will be identified and described from an operator’s perspective, and this will enable a commercial decision to be made with regard to investing in ERTMS trains, taking into account all of the technical aspects that this entails.
