After launching five new stations—Wat Mangkon, Sam Yot, Sanam Chai, Itsaraphap and Tha Phra—along the MRT Blue Line extension from Hua Lamphong to Bang Khae in late July, followed by the Bang Phai and Bang Wa stations in August, four more new stations running from Phet Kasem 48 to Lak Song are set to open on Saturday (Sep 21). 

According to the Mass Rapid Transportation Authority (MRTA), the trains will run from 5:30am-11:05pm on weekdays and from 6am-11:05pm on weekends, offering commuters one smooth ride along the whole line without having to transfer at Hua Lamphong station. The line will also offer free rides from Sep 21-29 before fares kick in (between B16-42 per ride). 

The 14-kilometer extension covers a total of 11 stations, including four underground—Wat Mangkon, Sam Yot, Sanam Chai and Itsaraphap—before surfacing at Tha Phra and running overground to Bang Phai, Bang Wa, Phet Kasem 48, Phasi Charoen, Bang Khae and Lak Song, just beyond the provincial border in Phutthamonthon Sai 4.

Meanwhile, the MRT Blue Line’s second extension, which heads north toward Bang Sue, is expected to open on Mar 31 next year, with test runs starting this December. The 13-kilometer elevated line will cover eight stations that connect to MRT Tha Phra, where you can change to the Tao Poon-bound elevated purple line. These stations include Charan Sanit Wong 13, Yaek Fai Chai, Bang Khun Non, Bang Yi Khan, Sirindhorn, Bang Phlat, Bang Or and Bang Po. On top of that, MRT Bang Wa will also interchange with the BTS Silom line.
