1. The MRT purple line

Set to officially launch on Mother’s Day, Aug 12, the first section of the much-delayed MRT purple line will run between Khlong Bang Phai-Tao Poon. A trial period will commence in May, when you can ride for free, before the full fare kicks in (B14-42). This line is a much-welcomed development for residents of Nonthaburi. Of note for those living in central Bangkok, the line will take you straight to the massive Central Westgate Bangyai (see below), one of the city's more significant recent mega-mall openings. The purple line will connect with the existing Bang Sue station and eventually also run from Tao Pun-Rat Burana.

2. BTS Sukhumvit line

Since its conception in 1999, Bangkok's BTS skytrain has been operating on two lines—Sukhumvit and Silom—which presently service a total of 34 stations.

The Sukhumvit line is set to extend from Bearing through Samutprakarn and all the way to Bang Pu. Said to be operational by early 2020, the extension will cover seven stations and is supposedly 57.06-percent complete already. That will easily get you to the picturesque Ancient City (Muang Boran, below), the seaside Samutprakarn City Hall and Samutprakarn Crocodile Farm.

From Mo Chit, meanwhile, there is also a plan to extend to Saphan Mai through to Khu Khot, which is also expected to be completed in 2020, too. Highlights on this line include Kasetsart University, 11th Infantry Regiment (where the last Maya Music Festival was held) and the Royal Air Force Museum.


3. The MRT blue line

The MRT has been operating since 2004, with just the one line covering 18 stations. Construction to expand the current blue line from Hua Lamphong-Bang Kae (14km) will commence next year, and has been scheduled for completion within four years. That means your trips to explore the Old Town will be much more convenient as the line passes through Charoenkrung, Chinatown, Sanam Chai Road (Museum Siam and Wat Pho) and Pak Khlong Talad over to the Thonburi side of the city. The first 4km of the line from Hua Lamphong to Tha Phra will be underground, before it converts into an overground train for the rest of the journey to Bang Kae (9km). 


4. The SRT dark red line

Finally, the Bangsue-Rangsit dark red line, covering some 24.6km of Bangkok (and planned to connect to the North/Northeastern region of the country in the future) as part of the planned SRT Red Line suburban railway system, is scheduled to be complete by 2019 after some delays in the bidding process. Why we're excited? No more ungodly traffic time on the way to Don Muang Airport, improved access to MOCA (see below).

The other side of the MRT purple line 

Tao Pun-Ratburana 

Phase two of the MRT purple line is intended to serve the southern part of the city. The underground train will cover areas in the Phra Nakhon and Dusit district—that means Samsen Road, the national library, Thewet Market, Banglamphu (one of the world’s fastest growing Airbnb areas), the Golden Mount—before crossing to the other side of the river into Thonburi through Wongwian Yai and terminating at Rat Burana. Phra Pradaeng (home to the trending cycling destination Bang Krachao) will also be easier to access. So far, this phase has not yet received cabinet approval.
The new orange line

Taling Chan-Thailand Cultural Center-Minburi 

After much rerouting due to resident protests, the Thai cabinet has finally approved the construction of the orange line. This will also pass a lot of the city’s major sights serving people who live around Minburi. Other highlights include: Siriraj Hospital, Sanam Luang (Grand Palace and Tha Maharaj), Democracy Monument (RCAC and Rattanakosin Exhibition Hall), Lan Luang (Seven Spoons, Mad Moa, Talad Nang Loeng), Pratunam (Platinum Shopping Mall), Thailand Cultural Center and Hua Mak Stadium. Estimated completion in 2023.
