Bangkok has two elevated monorail lines in the suburbs: the Pink Line across the north, from Nonthaburi to Min Buri, and the Yellow Line in the east, from Lat Phrao to Samrong. Most short-stay visitors never need them, but they are the easy way to the Chaeng Watthana immigration office, to the Impact exhibition center at Muang Thong Thani, and across the eastern suburbs without going through the center.
Both lines carry the MRT brand but are run by companies in the BTS group, and both opened in 2023. They feed the main network rather than replace it: each one meets the BTS, the MRT and a third rail line at its interchanges.
This page covers the two lines only. The rest of the rail network is explained in our guide to using the BTS Skytrain and MRT, and tickets, contactless cards and the Rabbit card are on our page about paying for Bangkok's trains.

The Pink Line: Nonthaburi to Min Buri
The Pink Line, officially the MRT Wiwat Nakhon line, runs east–west across the northern suburbs for 30 stations, from Nonthaburi Civic Center (PK01) to Min Buri (PK30). The concession and operation belong to Northern Bangkok Monorail (NBM), part of the BTS group. It opened to passengers at the end of 2023.
It is a commuter line through the suburbs, not a sightseeing route. For visitors, three things make it useful: the interchanges, the Government Complex station and the branch to Muang Thong Thani.
Government Complex (PK12) is the station for Bangkok's main immigration office; our guide to the Chaeng Watthana immigration office explains the exit and the shuttle bus from there.
Pink Line interchanges
The Pink Line meets three other rail lines. NBM gives the exits to use:
| Pink Line station | Change to | Exit |
|---|---|---|
| Nonthaburi Civic Center (PK01) | MRT Purple Line | Exit 4 |
| Lak Si | SRT Red Line | Exit 1 |
| Wat Phra Sri Mahathat | BTS Sukhumvit Line | Exits 3 and 4 |
Each change means leaving one fare system and entering another. Both monorails take contactless Visa, Mastercard and UnionPay cards, but that card trip does not carry through into the BTS, so you tap out and pay again; the payment page linked above has the details.
Min Buri, at the eastern end, has the line's only Park & Ride car park.
The Muang Thong Thani branch to Impact
A 3 km branch leaves the Pink Line and serves two stations: Impact Muang Thong Thani (MT01) and Muang Thong Thani Lake (MT02). It had a free trial from 20 May 2025 and has carried paying passengers since Tuesday 17 June 2025. The branch runs the same hours as the main line, about 06:00 to midnight.
This is the line to use for concerts, trade fairs and exhibitions at the Impact center. Change on the main line near Muang Thong Thani station (PK10) and follow the MT signs. Reports conflict on the exact junction, so read the signs rather than any older map.
For Impact, look for MT01 on the signs, not the main-line Muang Thong Thani station. The main-line station (PK10) is not at the exhibition halls. You need the branch train to Impact Muang Thong Thani (MT01).
The Yellow Line: Lat Phrao to Samrong
The Yellow Line, officially the MRT Nakkhara Phiphat line, runs north–south through the eastern suburbs for 23 stations, from Lat Phrao to Samrong. The concession belongs to Eastern Bangkok Monorail (EBM) and the line is operated by BTSC. It opened to passengers in June 2023. Single-journey fares are 15 to 45 baht, and a single ticket is valid only on the day you buy it.
Its main value is as a north–south link between three other lines that otherwise only meet in the center. You can, for example, go from the MRT Blue Line in the north to the BTS at Samrong without riding into Sukhumvit.
Yellow Line interchanges
| Yellow Line station | Change to | Exit |
|---|---|---|
| Lat Phrao | MRT Blue Line | Exits 3 and 4 |
| Hua Mak | Airport Rail Link | Exit 1 |
| Samrong | BTS Sukhumvit Line | Exit 3 |
Hua Mak is worth knowing. It puts the Airport Rail Link one change away from the Yellow Line, which can help if you stay in the eastern suburbs and fly from Suvarnabhumi. Our guide to the Airport Rail Link covers that line and its stations.
Folding bicycles are allowed on the Yellow Line at any time; standard bicycles are not.
Hours and timetables
Both operators publish their own timetables, and the pages do not quite agree. The FAQ pages say the lines run from 06:00 to midnight, while the timetable pages show a first train at about 05:30 from the end stations and a last one around midnight. The Yellow Line ticket office is open from 06:00 to midnight. Plan on about 06:00 to midnight, and check the timetable for your station if you need the first or last train.
When the monorails are worth it, and when they are not
Take a monorail when:
- you have an appointment at Chaeng Watthana immigration or another office at the Government Complex;
- you are going to an event at Impact Muang Thong Thani;
- you are staying in the northern or eastern suburbs and want to reach the BTS, the MRT or the Airport Rail Link without a long taxi ride.
Do not bother if you are staying in central Bangkok and visiting the main sights. The temples, the river and the shopping districts are all on the BTS, the MRT or the river boats; see our three-day plan for Bangkok on a first visit or our guide to where to stay in Bangkok. For Chatuchak and the Red Line, the main station is Krung Thep Aphiwat, not a monorail stop.
If you leave something on board, tell the station supervisor. On both lines, items not collected the same day are stored for up to a year; our guide to lost property in Thailand has the details for every operator.
