The British-built Circle Line began operations in 1959 and currently serves over 20,000 passengers each day.

Objectively, the Circle Line train cars are far from comfortable with unaccommodating chairs, bad suspension, and open-air compartments that expose riders to rain, insects, and sometimes sweltering heat.

But now this traditional ambiance and affordable access to travel is threatened by change.
The Yangon Circular Railway is owned and operated by the Burmese government and has been running at a substantial daily loss -- an economically unsustainable proposition.
