The Bangkok – Chiang Mai High-Speed Railway (also known as the Northern High-speed Railway) is a proposed high-speed railway that would be built alongside the current Northern Line in Thailand.
Japan has proposed building the railway in partnership with Thailand, and the line would be a Shinkansen-like bullet train similar to that used in Japan.
The project was first proposed in 2011, and a memorandum of cooperation (MOC) was reached in 2015. Japan released its study of the project in 2017, estimating that it would cost up to 420 billion baht to build (approximately $12.9 billion USD). Thailand wanted Japan to be an invester in the railway, while Japan was only interested in providing loans for the project. At that impasse the project has not progressed since 2018, though it still remains on the table as of 2021.
The length of the railway would be 670 km with 12 stations. The top speed would be 300kph, and the trip would take about three and a half hours. For comparison, the current line is 755 km and the journey takes from 11 hours to 14 hours and 20 minutes. The new line shortens the length because it uses tunnels and viaducts, while the old line meanders along the flattest path. The new line also shortens the trip by 8 km by starting at the new Bang Sue Grand Station in Bangkok.
To reduce the cost of the project, Thailand has also suggested reducing the top speed to 180kph and 200kph (which is technically not a high-speed railway). Such a railway would be comparable to the China-Laos railway and InterCity railways in Europe, and it would still be an improvement on the current railway. A trip of four and half hours would be a competitive alternative to flying.
Another consideration is that the railway would be shared with the planned Chiang Rai Railway, branching off at Den Chai.
Whichever system is built, it would be on a standard gauge railway and separate to the current metre-gauge railway. This duplication of railways is the same scenario with the current metre-gauge Northeastern Line and future standard-gauge Thai-China HSR.
