The one-line version: drive. Sing Buri has no railway station and no airport of its own, and it has one of the best trunk roads in central Thailand running the length of it — Highway 32, the Asian Highway carrying AH1 and AH2, six to eight lanes, part of the Kunming–Bangkok Expressway, with Bangkok about 140 kilometres south. In the capital you can walk. For everything else, and especially for In Buri at 314 square kilometres, a car is not optional.
Every way of moving around the province
| Mode | Verdict | Detail |
|---|---|---|
| Car | The default, and the only complete answer | Sing Buri is 822 km² across six districts with no rail and no air link inside its borders, and In Buri alone is about 314 km². A car covers the province, the run east to the railway at Lopburi 2, the run south to Ang Thong and Ayutthaya, and the roughly 140km trip to Bangkok. Everything below is a partial substitute for one. |
| Motorbike | Fine for the capital, limited beyond it | Mueang Sing Buri is compact and flat — the whole province is, with no ground above about 17 metres — so a motorbike genuinely covers the capital and its immediate surroundings. It is a poor tool for Highway 32, which is a six-to-eight-lane trunk route carrying long-distance freight between Bangkok and the North. |
| Highway 32 (AH1 / AH2) | The spine of the province | The Asian Highway begins at Bang Pa-In in Ayutthaya at the junction of Phahonyothin Road and the outer Bangkok ring road, then runs north through Ang Thong, Sing Buri and Chai Nat before merging back into Phahonyothin at the Nakhon Sawan border. It was a toll road until the mid-1990s — two of the old toll booths still stand, now used as an administration building — and was widened from four lanes to six, in places eight, between 2008 and 2009 to carry Bangkok–Nakhon Sawan traffic. It is also part of the Kunming–Bangkok Expressway. |
| Route 309 | The southern link | Runs south from the Sing Buri area through Phrom Buri toward Ang Thong and on to Ayutthaya. Several properties currently advertised for sale in Phrom Buri district are marketed on their Route 309 frontage, which is a fair indication of how the district orients itself. |
| Intercity bus | The realistic public option | Sing Buri sits on the main Bangkok–North corridor, so long-distance coaches pass through it constantly. We have not verified a current timetable, operator list or terminal address for the province and do not publish one — check locally or at the point of sale, because provincial bus schedules change more often than any published source keeps up with. |
| Rail | None inside the province | There is no railway station anywhere in Sing Buri. The State Railway's Northern Line runs east of it through Lop Buri. See the section below — the nearest long-distance platform changed in December 2025 and is now closer and newer than it was. |
| Air | None inside the province | No airport in Sing Buri. Bangkok's two airports are the practical answer, reached down Highway 32. |
The railway question, which changed in December 2025
| Station | Type | Location | Why it matters to Sing Buri |
|---|---|---|---|
| Lopburi 2 (Tha Wung) | Class 1, elevated — opened 5 December 2025 | Pho Talat Kaeo subdistrict, Tha Wung district, Lop Buri — 141.757 km from Bangkok railway station | The nearest long-distance platform to Sing Buri, and it is brand new. Built on the Lop Buri bypass branch of the Northern Line as part of the Lop Buri–Pak Nam Pho double-tracking — the bypass exists because the mainline runs adjacent to Phra Prang Sam Yot and could not be doubled without risking the monument. It has replaced Lopburi station as the stop for special express, express and rapid services between Bangkok and Chiang Mai, and it is the only elevated station in Lop Buri province. Tha Wung district borders Sing Buri. |
| Lopburi | The original city station | Lop Buri city | Still open, now handling commuter, local and freight services rather than the long-distance ones. The State Railway runs a free shuttle bus between Lopburi and Lopburi 2 stations. |
| Ban Phachi Junction | Where the Northern and Northeastern lines split | Ayutthaya province, south | Relevant if you are heading for the Northeast rather than the North. It is also the southern end of the new Suphan Buri–Nakhon Luang–Ban Phachi dual-track line the State Railway has approved — a project in the neighbouring provinces, not in Sing Buri, and we make no claim about its schedule. |
This is the one part of Sing Buri's transport picture that has genuinely moved recently, and it moved without a metre of track being laid inside the province. Until December 2025 the practical rail answer for Sing Buri was Lopburi station in the middle of Lop Buri city. Since 5 December 2025 the long-distance services — special express, express and rapid, in both directions between Bangkok and Chiang Mai — call instead at Lopburi 2 (Tha Wung), an elevated station in Tha Wung district, which borders Sing Buri. The State Railway runs a free shuttle between the two stations for anyone who needs the old one. The net effect for a Sing Buri resident is a newer, closer platform on a double-tracked line: still not in the province, but no longer on the far side of a city.
What we could not verify, and are not publishing
Three gaps, stated rather than filled. We publish no bus timetable, operator list or terminal address for Sing Buri: provincial coach and songthaew schedules change constantly and we could not confirm a current one against a source that stands behind it. We publish no drive times — not to Lopburi 2 station, not to Ayutthaya, not to Bangkok — because we could not verify any of them, and a made-up journey time is worse than none when someone is planning around a hospital appointment or a train. And we make no claim about the Suphan Buri–Nakhon Luang–Ban Phachi dual-track line beyond noting that the State Railway has approved an alignment for it; that project runs through Suphan Buri and Ayutthaya, not Sing Buri, and its schedule is not something we have confirmed. The road figures on this page — the highway's route, its lane widening, its Asian Highway designations and its toll history — come from published sources and are the parts we stand behind.
