It is also noted that Three-track track is used at Iriuda station to allow mainline train that using narrow gauge to reach Hakone-Yumoto and mountain train using standard gauge to reach Iriuda Depot, smilar to Yamagata Shinkansen

water storage system is used to prevent damage to railroad during tough curve. However, I can not confirm if such system is used for newer model.
