Adif expands rollout of ASFA driving assistance system
ASFA Digital (Automatic Braking and Announcement of Signals) is now in use on three more commuter lines, Adif announced on Sunday. With the rollout, the Spanish infrastructure manager is targeting improvements in punctuality.
ASFA was implemented on the Oviedo-Infiesto and Oviedo-San Esteban Cercanías lines, as well as on the Oviedo-Santander medium-distance line. The Gijón-Cudillero, Gijón-Laviana and Gijón-Oviedo-Trubia commuter lines already make use of the system.
ASFA Digital is a system that uses beacons along the track to monitor speed and braking. As it is a driving assistance system, it does not provide monitoring on board.
Now that the system is in use, 65 trains will make use of the Oviedo-Infiesto line on a daily basis, with 40 journeys scheduled on weekends and during holidays. The number of daily trains on the Oviedo-San Esteban line will grow to 61.
Adif has earmarked close to 3,9 million euros for the use of ASFA on trains using the metric gauge network.
