The first mast for the construction of overhead catenary cables was erected at Tegal Luar Station of Jakarta-Bandung High Speed Railway (HSR) on June 16, the railway's operator said.

At 10:00 am, workers of China Railway Group Limited Jakarta-Bandung HSR Project erected the first mast, which is numbered 41, with the help of a crane.

The building of HSR catenary system usually starts after the on-the-ground construction of bridges, tunnels, railways and stations were finished.

With a speed of 350 km per hour, the high-speed railway built with the Chinese technology will cut the journey between Jakarta and Bandung, the capital of West Java province, from more than three hours to around 40 minutes.
