The Spanish AI 99 is designed for “High-Speed-Track” up to 350 km/h. Characteristics: international European gauge = 1435 mm, tensioning force = 450 kN, sleeper’s net weight >315 kg. The waisted shape reduces load in sleeper’s centre especially with reference to “consolidated track” conditions. It also improves resistance against lateral movement that highly affects the track’s stability.
