VIENTIANE (Xinhua): China Railway No 2 Engineering Group (CREC-2) has welded the first seamless rails for the China-Laos railway in the northern suburb of Laos capital Vientiane since Thursday, said officials on Friday (June 19).
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, and enhance travel comfort.
