WEST BANDUNG REGENCY, Indonesia, Sept. 30 (Xinhua) -- The Tunnel No. 10 of Indonesia's Jakarta-Bandung High-Speed Railway (HSR) in West Java province on Wednesday safely traversed a 100-year-old existing railway line, making another breakthrough among the whole line of Jakarta-Bandung HSR.
Located in the low hilly area of Padalarang, a sub-district in the West Bandung district, the Tunnel No. 10, surrounded by Grade-VI-rocks which are easy to collapse, under-passes the existing railway at a large angle. The existing railway is a small-radius meter-gauge ordinary single-track railway built 100 years ago.
