Den Chai Chiang Rai Chiang Khong New Double-Track Railway (12/12/2020) The Cabinet on 8 December 2020 approved a draft Royal Decree, designating land expropriation boundaries in certain areas for implementing the new double-track railway between Den Chai, Chiang Rai, and Chiang Khong in northern Thailand. The areas include some parts of Den Chai, Sung Men, Mueang Phrae, Nong Muang Khai, and Song districts in Phrae province; Ngao district in Lampang province; Mueang Phayao, Dok Khamtai, and Phu Kamyao districts in Phayao province; and Pa Daet, Thoeng, Mueang Chiang Rai, Wiang Chai, Wiang Chiang Rung, Doi Luang, and Chiang Khong districts in Chiang Rai province. The Den Chai Chiang Rai Chiang Khong double-track railway project aims to facilitate goods transportation from Thailand to China through two major channels, namely Chiang Saen Commercial Port and the fourth Thai-Lao Friendship Bridge (Chiang Khong) in Chiang Rai. The length of the railway is 308 kilometers, with a maximum speed of 160 km per hour. The project requires an investment of 79,619 million baht, and it is expected to be completed in 2025. It comprises four tunnels, with a total length of 13.4 kilometers. When it is open for service, 4,811 people are likely to use this service each day. The project is expected to accommodate 313,669 tons of products from Thailand each year. When products from China are included, the volume will increase to about 1.6 million tons a year. The Bureau of the Budget stated that it would allocate a budget for the project, based on necessity and suitability, after the draft Royal Decree took effect. 29/09/2021 Page 1 กรมประชาสัมพันธ์.
