Kanbara Tunnel is a tunnel on Tokaido Shinkansen operated by Central Japan Railway Company located between Shin-Fuji Station and Shizuoka Station with total length of 4.934 km. It was built and completed in 1968. It is located after Shin-Fuji station and crossing the Fuji River, westward from Tokyo towards Osaka direction. The 0.294 kPa air pressures within the train cars inside Kanbara tunnel were managed according to the initial plan, preventing any auditory discomfort. It illustrates that the computer simulation outcomes align closely with the experimental data.
