The line is 414.332 kilometres, of which there is 258.5 kilometres of bridges and tunnels. The railway is standard gauge (same as China and Europe) and will be electric trains. The old railways of Southeast Asia still use metre-gauge, so Thailand is building a new railway to be able to connect with this line. The line is on a single track with passing loops. A double track would have been preferable, but given how many bridges and tunnels are being built this is an economic choice. Trains will have a maximum speed of 160 kph between Boten and Vang Vieng, and 200 kph between Vang Vieng and Vientiane. Cargo trains will be able to travel at 120 kph. There are 21 stations planned, with another 12 built in the future: 1. Boten 2. Nateuy 3. Na Mor 4. Muong Xai 5. Ban NakhokTay 6. Huoi Phoulai 7. Luang Prabang 8. XiengNge...Get price
