All seamless rails welded along China-Laos railway in Vietnam

China Railway No. 2 Engineering Group (CREC-2) has welded the last two 500-meter seamless rails for the China-Laos railway in the southern suburb of the Lao capital Vientiane.

The seamless rail, also known as continuous welded rail (CWR) which eliminates rail joints, can improve the duration of steel rails, reduce the maintenance costs of locomotives and tracks, improve the stability and speed of trains, as well as enhance travel comfort.

According to the Laos-China Railway Co., Ltd. (LCRC), a joint venture based in Vientiane in charge of the railway's construction and operation, the CREC-2 has completed the welding of all the seamless rails along the over 400-km railway on Thursday, thus laying a solid foundation for the goal to complete the China-Laos railway construction by the end of this year.

Xiao Qianwen, the LCRC general manager, told Xinhua on Friday that the Chinese engineers have welded the seamless rails across all the 75 tunnels, 165 bridges and 20 railway stations since May 2020.

According to Xiao, most projects of the China-Laos railway are undergoing the final check and acceptance inspection, and the remaining engineering and preparation for operation are progressing steadily.

The China-Laos Railway is a docking project between the China-proposed Belt and Road Initiative and Laos' strategy to convert itself from a landlocked country to a land-linked hub.

The over 400-km railway will run from Boten border gate in northern Laos bordering China to Vientiane with an operating speed of 160 km per hour.

The electrified passenger and cargo railway is built with the full application of Chinese management and technical standards. The construction of the project started in December 2016 and is scheduled to be completed and operational in December 2021.
