Bangkok–Nong Khai high-speed railway

Bangkok-Nakhon Ratchasima high-speed railway

The Bangkok–Nong Khai high-speed railway is a planned railway that will connect Bangkok to Nong Khai in northeast Thailand on the Laos border. It will then be connected to the China-Laos railway in Laos, providing a railway connection from Bangkok to Vientiane, and onwards to Kunming in China. This new railway is a double-track standard-gauge line that follows the same route as the current Northeastern line.

The project is also referred to as the China-Thailand Railway project, in reference to being built in partnership with Chinese companies (China Railway International and China Railway Design Corp).

The new railway was first proposed in 2010 alongside four other proposed high-speed railways from Bangkok. After years of delays due to terms of the arrangement with China and the 2014 coup, work officially began in 2017 before being delayed again. The project is now back on track, and the first stage between Bangkok and Nakhon Ratchasima is scheduled to open in 2023.

Phase 1 of construction is for the 253km section between Bangkok and Nakhon Ratchasima, at a cost of Bt50.63-billion ($1.67 billion USD). Stations in this section include Bang Sue, Don Muang, Ayutthaya, Saraburi, Pak Chong, and Nakhon Ratchasima.

Phase 2 of the 354.5km section from Nakhon Ratchasima to Nong Khai is still in draft. The stations will include Nakhon Ratchasima, Bua Yai, Ban Phai, Khon Kaen, Udon Thani, and Nong Khai.

A new bridge will be built on the Thailand-Laos border for the railway.

The total length will be 607.5 km long with an operating speed of 250 km/h. By comparison, the current Bangkok–Nong Khai railway is a length of 647.5 km and takes 9 hours and 25 minutes (an average speed of 68 km/h).

The new railway will be able to travel between Bangkok and Vientiane in under 3 hours, making it a competitive alternative to flying. Bangkokians will have the opportunity to take weekend trips to Luang Prabang by rail. It will turn Ayuthaya into a viable Bangkok commuter city, and it will put the Isaan cities of Nakhon Ratchasima, Khon Kaen, and Udon Thani within a day trip to Bangkok.

The current Bangkok–Nong Khai railway is a single-track metre-gauge railway. It is currently being double-tracked, and the line will be retained for local and freight services. There will be new stations built for the high-speed line, and in Bangkok the railway will depart from Bang Sue Grand Station.

The China-Laos railway (Boten-Vientiane railway) is expected to be completed by the end of 2021, so by the time the Bangkok–Nong Khai project is finished it will be ready to travel to Vientiane and the rest of Laos.
