The metro line, one of the eight urban railway projects connecting the city downtown and satellite urban areas, aims to reduce traffic overload in the western part of the capital city. It was put into operation on November 6, 2021. After more than two months of operation, the metro line has been running smoothly and safely.  On average, the line transports nearly 15,000 passengers per day. With total investment of around 886 million USD, funded by Chinese ODA, the elevated line is more than 13km long and has 12 stations and 13 trains. Each train, whose designed speed is 80 km per hour, has four carriages capable of carrying over 900 passengers./.
