The Gold Line is an automated people mover line, part of Bangkok's rapid transit system. The line is 1.8 km (1.1 mi) long, consisting of 3 stations,[2] and was opened by Thai Prime Minister Prayut Chan-o-cha on 16 December 2020.[3] It primarily serves as a feeder line between the BTS Silom line and Iconsiam shopping center. The line will be extended 1 km (0.62 mi) along Somdet Chao Phraya road to connect with the future MRT Purple Line southern extension. When completed, it will connect Krung Thon Buri BTS station with Prajadhipok Road in Thon Buri District for a total distance of 2.68 km (1.67 mi).
The line was not part of the current M-Map Master Plan as the line was proposed by the owners of Iconsiam mall in July 2015 to provide a feeder service to Iconsiam.[5][6] The project was approved by the Thai Cabinet in September 2016 with an initial planned opening of late 2018.[7] Preliminary works began in June 2018 with major construction commencing in September 2018.
Design and development of the line was the responsibility of Krungthep Thanakom PCL, an enterprise of the Bangkok Metropolitan Administration.[8] The project budget of 3.8 billion Thai baht was fully funded by the proponent of the project, shopping mall company Siam Piwat who has responsibility for all construction costs.[9] All advertising revenue and operating profits will be collected by Siam Piwat Company during the 30 year concession period.
At the end of August 2020, overall work for the Gold Line was 95% complete.[10] The line was due to open on 1 October 2020[11] and initial test runs began on 11 September.[12] However, further test runs revealed that additional tests would be required of the signaling and operational systems before full operations could start.[13] The President of the BTSC stated that a further two months of tests were required and that the line would not open until December 2020.[14] In early December, an opening date of 16 December 2020 was announced.[15] Upon opening, a one-month free travel period was in effect until 15 January 2021.[16]

Khlong San station platformThe railway of the Gold Line at front of Wat Suwan Temple
The Gold Line starts adjacent to Krung Thon Buri BTS station running 500m east to Charoen Nakhon road, where it then runs north for 1.3 km (0.81 mi) past Iconsiam. It will initially terminate at Klong San station near Lat Ya road intersection and provide an interchange with the future SRT Dark Red Line southern extension.
Future 1 km extension
The line will then be further extended 1 km (0.62 mi) west along Somdet Chao Phraya road and terminate at Phrajahipok road to connect with the future MRT Purple Line southern extension, which is scheduled to open in 2027. The 1 km (0.62 mi) extension was originally planned to open in 2023, but will now open in later years.
Services
Gold Line trains operate from 06:00 to 00:00 with a frequency range of six to twelve-minute intervals.[17] During the free fare period for the first month of operations in January 2021, the line was averaging between 5000 and 6000 daily passengers with 3000 using Iconsiam station.[18]
Rolling stock
The Gold Line uses Bombardier Innovia APM 300 automated people movers with rubber tyres manufactured by CRRC Puzhen Bombardier Transportation Systems (joint venture of Bombardier Transportation and CRRC Nanjing Puzhen) in Wuhu, Anhui, China. Innovia APMs are commonly used at airports to transport passengers between terminals. Each set has two carriages with 138 passenger capacity in each carriage, and can travel at a maximum of 80 km/h (50 mph).[19] The first set was due to be delivered in April 2020, but was delayed due to a COVID-19 related lockdown in Anhui province.[20]
The first set later arrived in Thailand on 18 June 2020, the remaining 2 sets were delivered in August 2020.[11]
