International services

Until 2016, SRT operated international services to Butterworth in Penang, Malaysia, in conjunction with Malaysian state operator KTM. Direct trains from Bangkok now only run as far as Padang Besar, due to the opening of KTM ETS.

Since 2021, there 3 return trains operate from Hat Yai Junction and terminate at Padang Besar across the Malaysia–Thailand border. SRT has also historically allowed operation of the Eastern & Oriental Express on its tracks which runs from Singapore to Bangkok and vice versa, although trips in 2024 did not enter Thailand.

A link across the First Thai–Lao Friendship Bridge to Thanaleng railway station, near Vientiane, opened in March 2009. In December 2010, following Chinese plans to extend their standard-gauge railway network to Xishuangbanna on the China–Laos border and further into Laos, the Thai government agreed to start negotiations on building a standard-gauge network. This would initially involve two lines: from Bangkok to the Lao border, and a longer line from Bangkok along the peninsula to the Malay border. In 2024, long distance overnight train services between Bangkok and Vientiane Khamsavath railway station were started. Shuttle trains to Udon Thani are also being operated in conjunction with the Lao National Railway.

The rail link to Cambodia via Poipet from the railhead at Aranyaprathet was constructed in 1941, but was closed in 1961 due to strained Thai-Cambodian relations during the Cold War. The rail connection was repaired and reopened in April 2019. Cross-border services briefly ran until it was suspended by the outbreak of COVID-19. Currently, no cross-border services operate. and due to war between border of Cambodia result to temporary out of service.

Railway connections to Myanmar (Burma), notably the infamous Death Railway, are defunct.

Commuter trains

The SRT operates commuter rail services from Bangkok along the Northern and Northeastern Lines up to Ayutthaya, Ban Phachi Junction, Lopburi and Kaeng Khoi Junction. Ten trains run along the route on a daily basis. A new service serving between Thon Buri and Salaya was launched on 22 October 2010, extending to Nakhon Pathom on 1 June 2022 to act as a feeder service for the SRT Light Red Line.

The Red Line project is a new commuter rail system also owned by the SRT and will replace portions of rail lines running through Bangkok, eliminating at-grade crossings. Currently, two lines operate: the Dark Red Line and the Light Red Line.

Freight

Thai railways transported around 11 million tons of freight per year in 2007–2012, which was around 2% of the total amount of freight moved by all modes of transportation. While it is possible for freight trains to travel between Thailand and the neighboring countries (Malaysia and Laos), the amount of international rail freight presently constitutes only a minuscule portion of Thailand's foreign trade. In 2012, merely 95 thousand tons of export cargo left Thailand by rail, as compared to 12 million tons of cargo exported by road, and 114 million tons of cargo exported by ship. For import, the rail transport's share was even smaller.

Thai railways transport both bulk freight (primarily oil products and construction materials) and containerized freight. Most of the freight movement is between Bangkok and sea ports (in particular, between the deepwater port of Laem Chabang and the container terminal in Lad Krabang, in Bangkok's eastern suburbs).

In an attempt to increase the railway's share of the nation's freight transportation market, in 2016 the SRT, in a joint project with Japan, started experimenting with small, 12-foot containers. It is thought that, being smaller than the standard 20-foot containers, these containers can be more easily transported by truck between a rail station and the end customer. These containers are being tried on two routes from Bangkok's Bang Sue station: a 722-km route to Lamphun Province in the north of the country, and a 433-km route to Khon Kaen in the northeast.

Excursion and tourist trains

SRT also operates special services aimed at tourists, such as the SRT Royal Blossom train, SRT KiHa 183 Excursions, steam train services and weekend Nam Tok Sai Yok Noi and Suan Son Pradipat province. Most of these special services feature special trains, and are priced at a premium, with added services.

Refurbished old KiHa 183 trains debuted on the SRT network, gifted by the JR Hokkaido Railway Company, are now some of the excursion train services, providing day and overnight tours to different provinces such as Ayutthaya, Hua Hin, Chacheongsao, Nakhon Nayok and Nam Tok Sai Yok Noi.
