Orange Line, Bangkok

The Orange Line is a proposed rapid transit system that will connect the Thailand Cultural Centre in Huai Khwang district to Min Buri district in eastern Bangkok. The 21.2km electric railway line will include a 12km underground section and a 9km elevated section, and will serve approximately 114,000 passengers a day.

A planned second phase of the line will extend the route by 17.5km to Taling Chan, which will increase the ridership to 500,000 passengers a day with both the phases operative.

The government-approved the Orange Line to expand the metro network in the Bangkok metropolitan area and reduce the road traffic congestion. The prime goal is to lower the use of cars and the budget on oil imports and reserves.

The project is proposed to be built in two phases. The first phase is planned from Thailand Culture Centre to Min Buri and the second phase would extend the route to west towards Taling Chan.
