Bangkok BRT - Sathon–Ratchaphruek Route

Sathon–Ratchaphruek Route

The first route from Sathon to Ratchaphruek via Narathiwat Ratchanakharin and Rama III roads, opened to the public on 29 May 2010. This was later than 12 August 2008 as originally planned. The service ran as a free trial until the end of August 2010, followed by a flat fare of THB10 from September 2010, which as of January 2013 is still the current rate.

Part of the route is physically separated from the remaining carriageway by way of surface-mounted dividers, while other parts of the route are high-occupancy vehicle lanes with a minimum occupancy level of three occupants (T3). The vehicles have a guide system, which is only used at the stations to ensure a minimum gap between the station and the bus. The stations are all located in the centre of the road, which means that the BRT lanes are located against the road median, and the doors are on the right hand side of the buses (Thailand drives on the left). Access from the stations to the vehicles is level.
