Get a ticket to ride everywhere in Bangkok

The joint-ticketing system will ease financial burdens on commuters as they can gain access to all forms of mass transit _ elevated trains, subway trains, buses and boats _ by using a single ticket.

Under the original master plan, construction of 10 mass-transit rail lines in Bangkok and surrounding provinces with a distance of 410km will start within four years and work will be completed between 2015 and 2019. Those electric railway routes will be extended to 464km by 2029.

The mass-transit rail lines require a total investment of 397 billion baht. Two projects are in the bidding stage and six more projects are expected to enter the bidding stage this year.

Authorities have set the timeframe to call bidding for eight projects in 2015. After 2019, five mass transit line extension projects will be built. Of the 10 lines, the Airport Rail Link (Phaya Thai to Suvarnabhumi Airport) has been built and the Light Red Line's 15km section from Bang Sue to Taling Chan is 85% complete.

The other eight projects are the Dark Red Line with a distance of 80.8km, Dark Green Line (66.5km), Light Green Line (55km), Blue Line (55km), Purple Line (42.8km), Orange Line (32.5 km), Pink Line (36km) and Yellow Line (30.4km).
