The way of transport like tunnel and bridge is very modern engineering wonders even if human have been making them for thousands of years. Juman starts to excursive the tunnels out of gigantic granite walls along with chisels, and hammers. Due to the hill’s topography, the most important and longest tunnel in the world is reduced drastically the transit time in western destinations.
Here is the list of the top 10 longest Railway tunnels:
10. Geumjeong Tunnel (South Korea)

The tunnel was made via the Mikuni Mountain range following the blast and drill digging methods. Within 10km intervals, one can get to evacuation sites.
7. Iwate-Ichinohe Tunnel (Japan)
Length: 25.8 km
Iware-Ichinohe tunnel in Japan is mainly the seventh-longest railway tunnel the total length of the tunnel is 25.81 km. In August 1991, the work of the tuner started, and finished in 2000. After an earthquake in 2011, the tunnel services were paused. In the single bore twin track in the form of horseshoe form also used in the tunnel design, it measures 9.8m broad and 7.7m high.
6. Hakkoda Tunnel (Japan)
Length: 26.5 km
This tunnel has a length of 26.45 km. The Hakkoda tunnel is known as Japan’s longest land-based double-track railway tunnel. The sixth longest rail tunnel in the world. This tunnel is located in Tenmabayashi-mura and Aomori Prefecture, Japan.
5. Taihang Tunnel (China)
Length: 27.8 km
