Railways
Inter-city Railway
For list of railway route relations, see Thai railway network
The inter-city railways form the mainlines of long-distance passenger and freight services across the country. This network is operated by the State Railway of Thailand (SRT) and comprises 4 principal lines radiating from Bangkok: the Northern Line, the Northeastern Line, the Eastern Line, and the Southern Line.
All inter-city railway lines in Thailand use the meter gauge (1000 mm), consistent with regional standards in Southeast Asia. Newly constructed double-track segments are equipped with ETCS Level 1 train protection signaling systems. However, as of 2025, none of the inter-city lines are electrified, and all services currently rely on diesel or battery traction. Hence, inter-city railways in Thailand should generally be tagged as follows:
railway=rail– for mainline railways used for long-distance travel.gauge=1000– to specify the meter gauge.electrified=norailway:etcs=1– on sections with ETCS level 1 signaling (most double-track projects since around 2020).usage=main/branch/industrial/military/tourism/science/leisureservice=yard/siding/spur/crossover- other related tags
Inter-city Railway Station
Inter-city railway stations in Thailand are classified into seven categories, which reflect the relative importance of each station and determine the stopping patterns of train services. These categories are part of the national classification system administered by the State Railway of Thailand (SRT). The seven station classes are:
- Class 1 – Primary stations located within major cities or provincial capitals.
- Class 2 – Secondary stations typically found in large towns or district centers. They are staffed and offer basic services but with fewer train stops than Class 1 stations.
- Class 3 – Tertiary stations, often located in smaller towns or rural areas, with limited facilities and less frequent service.
- Class 4 – Low-traffic stations with minimal infrastructure.
- ที่หยุดรถ (Halt) – Unmanned stopping points with no station building. Trains stop here as part of the schedule, usually to serve small communities.
- ป้ายหยุดรถ (Flag Halt) -Operationally similar to ที่หยุดรถ (Halt), these are halts where trains stop without full station status. While the distinction is subtle, official documents treat these as a separate category.
- พิเศษ (Special) – Stations with unique or restricted roles, such as those used for ceremonial purposes, military access, or located near royal properties.
Noted that although ที่หยุดรถ (Halt) and ป้ายหยุดรถ (Flag Halt) serve nearly identical functions in practice, they are maintained as distinct categories in official railway records.
Station Tagging Guidelines
railway=station– For all physical stations, halts, and stopping points.railway:station_category=1/2/3/4/ที่หยุดรถ/ป้ายหยุดรถ/พิเศษ– Use the official classification value to reflect the station's importance and stopping behavior.ref:station=****– Four-digit numeric station code as defined by the State Railway of Thailand (e.g., ref:station=1080).railway:ref=**– Two-character Thai-script code used for official reference and internal documentation (e.g., railway:ref=จก).- other related tags
Bangkok Metropolitan Region Railway
For list of metro/railway route relations, see Transits in Bangkok Metropolitan Region
The Bangkok Metropolitan Region Metro refers to the urban and suburban rapid transit systems serving the Bangkok metropolitan area. These systems include various modes such as elevated metro, underground metro, and commuter rail, operated by multiple agencies including the Mass Rapid Transit Authority of Thailand (MRTA), Bangkok Expressway and Metro Public Company Limited (BEM), BTS Group, and the State Railway of Thailand (SRT) for suburban commuter lines. Most metro lines use standard gauge (1435 mm) and are electrified, while commuter rail services like the SRT Red Lines operate on meter gauge but are also electrified with overhead lines.

Highspeed Railways
Thailand is currently developing a new high-speed railway network. As of 2025, 2 high-speed railway lines are under construction. These high-speed railways are designed and built with standard gauge (1435 mm) with full electrification via overhead catenary systems. They are entirely grade-separated and are not shared with the existing metre-gauge inter-city railways.
Use the following tags for high-speed railway tracks in Thailand:
railway=rail– For mainline railways.gauge=1435– Specifies the use of standard gauge track.highspeed=yes– Indicates the line is designed for high-speed train operations.electrified=contact_line– Used for lines electrified with overhead wire systems.voltage=25000+frequency=50– Electrification specification.usage=main– To indicate that the line is a primary trunk route.- other related tags
