Pavemetrics is delighted to have East Japan Railway Company (JR East) as a user of LCM-2 technology for tunnel inspection.<\/p>\n\n

JR East recently upgraded their Tunnel Lining Scanning Car (TuLIS) with 6 LCMS-2 systems, for an impressive total of 12 sensors. The new TuLIS system is capable of 1mm resolution 3D scans at 20km\/h and can automatically detect and quantify cracking in tunnel linings.<\/p>\n\n

The system is being used to scan tunnels on Japan\u2019s famous Shinkansen network (the \u201cBullet Train\u201d). The Shinkansen network carries over 350 million passengers annually, has a length of approximately 2,765 kilometers and trains travel at speeds up to 320 km\/h. The Shinkansen has numerous tunnels including significant ones such as the Seikan Tunnel which is 53.85 km in length and is the world\u2019s longest tunnel with an undersea segment.<\/p>\n\n

LCMS technology is helping JR East to increase measurement accuracy while importantly reducing the time required for inspections on this very busy network.<\/p>\n\n
