Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-89e97dc014f38e6d quantitative
Bangkok's rail network runs 13 lines under three agencies and their concessionaires
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The policy account lists the 13 lines and their agencies alongside the network's 279.84 km and 194 stations.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Thai PBS Policy Watch — conditions of the 20-baht scheme
Claim 2 clm-00c2a7ca39dd585e quantitative
A common card, Mangmoom, was promised from 2016, launched in June 2018 on two lines, then relaunched in 2025 as a bank-issued EMV card
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The established-press account documents the repeated common-ticket announcements and their non-delivery, which is what makes Mangmoom a promise from the mid-2010s that never reached the whole network. The EMV report records that the second-generation card covers six lines but not the BTS.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Bangkok Post — common ticket vows fall flat
  2. Nation Thailand — the MRT shifts to EMV contactless
Claim 3 clm-5ecdd2aa0331eca3 quantitative
bank cards have worked on the MRT Blue and Purple lines since January 2022 and became mandatory there on 1 June 2026
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator introduced EMV contactless on the MRT Blue and Purple lines in January 2022, with readers installed at 53 stations. The later report gives the transition dates: stored-value top-ups end 1 April 2026, EMV becomes mandatory on those two lines on 1 June 2026, and QR tickets replace single-journey tokens from 1 January 2027.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Brand Inside — EMV contactless arrives on the MRT
  2. Nation Thailand — the MRT shifts to EMV contactless
Claim 4 clm-576e6186611aa910 descriptive
The BTS Green and Gold lines still take only Rabbit cards
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The second-generation Mangmoom EMV card covers six lines but not the BTS, and the independent cost analysis states plainly that no single card spans both the BTS and the MRT.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Nation Thailand — the MRT shifts to EMV contactless
  2. Rocket Media Lab — the cost of the cards behind the flat fare
Claim 5 clm-29d1a5c64e891416 quantitative
A network-wide 20-baht flat fare was budgeted and opened for registration in August 2025 but slipped past its October launch awaiting legislation
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The scheme carried a 5,668 million baht budget — 5,512 million in operator compensation plus 156 million for a central revenue system — with app registration and a requirement to register an EMV or Rabbit card. The launch, originally 1 October 2025, was delayed to mid-November because the joint-ticket and MRTA bills had not completed their readings, with the transport minister apologising publicly. The instruments themselves are the MRTA Act (Amendment 2), gazetted 7 November 2025, the Common Ticket System Management Act and the Rail Transport Act.
Caveat
Eligibility was restricted to Thai nationals, a condition an independent analysis flags as a burden on migrant workers.

Sources carrying this claim

  1. Thai PBS Policy Watch — conditions of the 20-baht scheme
  2. Naewna — waiting in vain for the 20-baht flat fare
  3. Thai PBS Policy Watch — three acts open the way to a single fare
Claim 6 clm-1abcc8cf18d34039 quantitative
the cabinet dropped it in June 2026 for a 17-45 baht cap from 2027
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The cabinet decision of 23 June 2026 sets a common fare of 17-45 baht per trip from 1 January 2027 with one entry fee across transfers, formally cancels the 20-baht flat fare, and leaves the clearing house and subsidiary legislation outstanding. The second report confirms the structure and date.
Caveat

Sources carrying this claim

  1. Thai PBS Verify — cabinet approves 17-45 baht and cancels the flat fare
  2. Nation Thailand — cabinet backs the 17-45 baht rail fare cap for 2027
Claim 7 clm-09d58eec634bbece quantitative
The MRT Purple Line averaged about 66,000 trips a day after one year of the 20-baht cap, up 17.70% year on year
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
After one year of the cap the Purple Line averaged about 66,000 passengers a day, up 17.70 per cent. The authority's own release dates the cap on that line to 16 October 2023.
Caveat
Ridership data originates with the operator. The authority's page blocks automated fetching; headline and date were verified via the search listing and corroborated by a second Thai outlet. An independent analysis puts the expected effect lower: a research institute estimated the cap would raise ridership about 14 per cent, short of the roughly 30 per cent fare cut, and a free-fare week in January 2025 lifted core Blue and Purple weekday use only 20-30 per cent.

Sources carrying this claim

  1. Manager Online — one year of the 20-baht Purple Line measure
  2. MRTA — 20-baht maximum fare on the Purple Line from 16 October 2023
Claim 8 clm-6889ddb7097e279d descriptive
Open payment standards fixed the turnstile but not the concession contracts underneath, which is where fare integration actually stalled
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Acquiring certain routes would cost roughly 100 billion baht and some concessions run to 2029, so full state control is not immediately feasible. Meanwhile the flat fare was scaled back rather than extended: from 1 December 2025 the Purple and Red lines moved from the 20-baht cap to a 40-baht daily pass, 30 baht for students, accessible only with an EMV contactless card. And the card estate itself remains split — passengers must buy cards at 250, 200 or 150 baht, an estimated 58.6 to 364.7 million baht a year in total, with no single card spanning both the BTS and the MRT.
Caveat

Independent analysis of the fiscal and equity problems: the Thailand Development Research Institute estimated the cap would raise ridership about 14%, short of the roughly 30% fare cut; the January 2025 free-fare week lifted core Blue and Purple line weekday use only 20-30%; the Thai-citizens-only condition burdens migrant workers.

  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
