The Silver Line or Bang Na–Suvarnabhumi light rail is a proposed light rail line in Bangkok that would provide service from Bang Na to Suvarnabhumi Airport. Although not included in the Mass Rapid Transit Master Plan, in December 2015, the BMA said it would push for its construction and would propose it to the cabinet in the near future.^[1] In April 2016, deputy governor Amorn Kitchawengkul said the project would take 3–6 years and cost THB 20 billion. The project would relieve congestion on the Debaratana road.^[2]

The line initially appeared on the 1994 Mass Rapid Transit Master Plan (MTMP), before it was further improved in the 1996 CTMP. It was an extension to the Tanayong SkyTrain until it was canceled when Urban Rail Transportation Master Plan in Bangkok and Surrounding Areas (URMAP) was developed in 2000. Then, in a 2004 OTP meeting, it was decided that the route needed to be expanded to meet the need of the expanding Bangkok. The route was finally determined to terminate at the Sri Iam interchange and Suvarnabhumi Airport.

Project Details[]

• It is a light rail transit system that can be changed to heavy rail if desired by the operator.
• The rail gauge is 1.435 m (standard gauge), with a third rail running parallel with the track for electrification.
• It uses an automated signalling system and automatic fare collection.

Depot[]

There will be a 46,400 sq.m. depot at Thana City, which Bangkok will buy back the land from U City Public Co. Ltd., the owner of Thana City project.^[3]

Stations[]

This line's 14 stations include 13 elevated stations and 1 underground station.

Each station is approximately 250 meters long and 20 meters wide, equipped with platform screen doors. However, each above-ground station is 18 meters wide instead of 20.

Route[]

Bang Na–Thana City Section[]

This section starts at the Sunphawut road (in front of MEA Bang Na District, Bang Na District Office, and Phra Khanong Provincial Court), runs along the said road, pass Bang Na intersection, above the outbound Debaratana road's median, pass across Si Iam interchange which connects to MRTA Yellow Line, over the Kingkaew interchange which is a transfer point to , and terminate at Thana City. This section's ending terminus is at the 13th km of Debaratana road and the depot of the line itself.

Thana City–Suvarnabhumi[]

The line continues from the Thana City end of the previous section. It passes Central Village and Krirk University before crossing Nong Prue and Nong Ngu Hao canal. The ending terminus of this section is the south terminal of Suvarnabhumi Airport. As the south terminal is not yet finished,^[5] the mentioned route's construction will need to wait. However, AoT has modified the terminal to give the line direct access to the passenger building, unlike Suvarnabhumi ARL Station which was built in an unused Novotel Suvarnabhumi walkway.

Route Changes[]

• 2016 - The starting terminus was changed from Udom Suk BTS Station to Sunphawut intersection, in front of Phra Khanong Provincial Court and the new Bang Na District Office. This change will ease the trip to contact these government offices.
• May 2018 - OTP and JICA agreed to completely reconsider the route. The line was extended from Sanphawut intersection to run above Thang Rotfai Sai Kao Pak Nam Road, into At Narong Road, along Chalerm Maha Nakhon Expressway, turn to Rama III Road, and end at the Chao Phraya River. The area around the river terminus will be developed into a new SRT economic zone.^[6] Additionally, the cancellation of the route Thana City-Si Waree Noi Temple was discussed. Although the cancellation would decrease the length of the line, the focus was on moving people to and from Suvarnabhumi Airport. The aforementioned route is to be included in M-Map 2.
