This article concerns the systems of transportation in Laos. Laos is a country in Asia, which possesses a number of modern transportation systems, including several highways and a number of airports. As a landlocked country, Laos possesses no ports or harbours on the sea, and the difficulty of navigation on the Mekong means that this is also not a significant transport route.

Thanaleng station, also known as Dongphosy station, is a railway station in Dongphosy village, Hadxayfong district, Vientiane Prefecture, Laos. It is 20 km (12 mi) east of the Lao capital city of Vientiane and 4 km (2.5 mi) north of the Lao-Thai border on the Mekong River. The station opened on 5 March 2009, becoming part of the first international railway link serving Laos. Originally intended for use as a passenger station, Lao officials have stated their intention to convert it to a rail freight terminal to provide a low-cost alternative to road freight, the main mode of transport for goods entering Thailand. The station provides a connection between Vientiane and the capital cities of three other ASEAN nations: Thailand, Malaysia, and Singapore, and several major Southeast Asian ports.
