This figure surpasses the record set by the 13.1km Cat Linh-Ha Dong metro line, the first one to be operational in Hanoi and in the country, which saw 25,680 passengers on the opening day. The majority of passengers on the Nhon- Cau Giay metro section are people commuting to work or school. This suggests that passenger numbers on this route are likely to be significantly higher than on the Cat Linh-Ha Dong. The operation and management have been highly successful, ensuring safety and passenger satisfaction. At the stations, staff, train operators and security personnel efficiently carried out their duties. The ticketing and boarding processes were fully automated. The metro line spans 12.5 km, with the elevated section covering 8.5 km and the underground section covering 4 km. Once fully operational, the line is expected to help reduce traffic congestion and pressure on buses on the same route./.
