ASFA has been Spain’s national railways network train protection system for the last 30 years. It has been avoiding wayside signals overruns and thus enhancing traffic safety parameters over the years – but time spares no one. Components obsolescence has lead infrastructure administrator ADIF and operator RENFE to the specification of new technical and functional requirements for a new on-board ASFA system.
Since Dimetronic has been giving the technical and logistic support for the system for its entire life cycle, it has been awarded with the contract to develop the new requested functionality, the supply of the new sets of equipment and its installation in 80 ADIF trains and 400 RENFE vehicles.
