Thailand and Japan are preparing to begin the first-phase construction of a high-speed rail project linking Bangkok with Chiang Mai.

The 688-kilometre rail line will have 12 stations — Bang Sue, Don Mueang, Ayutthaya, Lop Buri, Nakhon Sawan, Phichit, Phitsanulok, Sukhothai, Sri Satchanalai, Lampang, Lamphun and Chiang Mai.

The project is divided into two phases, with the first running from Bangkok to Phitsanulok for over 380km, which then continuing to Chiang Mai for a further distance of 288km.

Japan has proposed using Shinkansen-style trains, which typically reach a maximum speed of 300kph.

This is seen as a key project capable of generating benefits for Thailand’s economy, the Department of Rail Transport said, adding it will strengthen ties between Thailand and Japan and pave the way for more successful projects in the future.

Thailand also proposed Japan conduct another study on the economic benefits for areas surrounding the high-speed railway, based on examples of railway stations in Japan.
