I thought it was time to update the above to reflect developments of the last 6 months as a couple of exts have advanced. Remember, the latest network map is linked earlier. MOT has said they are reviewing plans to ensure all is in accordance with their election network policy but the reality the new govt. will prioritise lines which will increase property prices in areas where their members have financial interests. A) Current lines under construction; 1) SRT Red Line from Bang Sue to Taling Chan (est open now late 2012) 2) BTS ext from Wong Wian Yai to Bang Wah (Dec 2012) 3) MRTA Purple Line from Taopoon to Bang Yai (opens early 2014) 4) MRT Blue Line ring ext (subway) and Bang Khae/Phetkasem rd ext (preliminary works started June. Completion 2016) B ) Lines tendered and contact to be signed 5) BTS Bearing to Paknam ext (awarded, contract to be signed, work expected to start Oct 11) C) Lines with a delayed tender 6) SRT Red Line from Bang Sue to Rangsit 6a) New Intercity terminal at Bang Sue for all N, NE & S intercity trains, D) Lines reportedly close to tender; 7) MRT Subway Blue Line ext from Bang Sue to Taopoon (1 station) - to interchange with the Purple line when it opens, E) Lines which have disappeared into a Thai policy vortex of confusion; 8) BTS Mo Chit to Saphan Mai ext (expected to be tendered next year but that has been said for the last 5 yrs. Original completion date was 2008), F) Next batch of lines: 9) Orange Line - at advanced planning and new priority due to HM's intervention. May be tendered 2012 10) Pink Line (mono-rail!) - considered a priority due to new Government Complex. Expect tender late 2012/early 2013. Sanity may prevail and it may become a heavy rail metro line. 11) Yellow Line G) Thereafter: 12) Purple Line ext south, 13) Red Line from Bang Sue to Hualumphong to Mahachai 14) Airport Line from Phayathai to Bangsue to Don Meung (DMK) 15) BTS ext from Saphan Mai to Lam Lukka 16) Line 11 and line 12???? H) Monorail: I didn't mention it before but the BMA has plans for 10 monorail feeder lines but to be frank most seem unlikely to advance. The reality is that a couple of monorail firms have been courting decision makers in the last few years pushing monorail projects for BKK. Hopefully most will not see the light of day.
