Nong Khai railway station

Originally, Nong Khai railway station opened at the location of the present-day Na Tha railway station as part of the Northeastern Line Udon Thani–Na Tha section on September 13, 1955. In July 1958, the line extended to near the Mekong River and the terminus station there was then the Nong Khai railway station, and the old was renamed Na Tha railway station. The station by the river acted as "Nong Khai" railway station for about 42 years, until the newer and present-day opened in May 2000 as Nong Khai railway station before Nong Khai Mai railway station. The station by the river was renamed to "Talat Nong Khai" and closed down in 2008.

On March 5, 2009, the Northeastern Line extended to Thanaleng in Laos across the First Thai–Lao Friendship Bridge,^[1] and international services between the present-day Nong Khai station and Thanaleng station began.

The metre gauge railway was extended to Khamsavath railway station several kilometres northwest of Thanaleng station and is located just 4 km from the centre of Vientiane. Freight transport by train between Nong Khai and Laos were increased to 24 round trips a day over the next five years, with each service consisting of 25 carriages, to handle growing cargo traffic from the rail link from standard gauge Boten–Vientiane railway, which opened in December 2021.^[2][3]
