Although it can feel like travelling in a washing machine on spin cycle, the Yangon Circle Line is a fun way to circumnavigate the city. It's a chance to interact with passengers and vendors on commuter trains (some have air-conditioned carriages) and see off-the-beaten-track areas of Yangon. The train is least crowded after 10am and before 4pm, and at weekends.
You're not locked into the full three-hour, 30-mile circuit: disembark at any of the 38 stations and take a taxi back to the city centre once you've had enough. You can use the train to avoid traffic-clogged roads and get close to northern attractions such as Meilamu Paya (Tadakalay station).
Trains leave from platform 6/7 at Yangon train station, accessed off Pansodan St; tickets are bought on the platform. Trains go in either direction and some don’t make the full circuit.
Note that a long ride on the Circle Line is not advisable if you suffer from travel sickness.
Changes are on the way: Japan has provided Myanmar Railways with US$200 million to buy 11 new six-carriage trains and upgrade tracks so that a circuit can be completed in less than two hours.
