How to read this map
This plots Singapore’s rail network in three confidence tiers, so it is always clear what is a plan and what is a guess.
- Solid lines — open today, or committed and under construction. Timings are LTA’s.
- Dashed lines — the Seletar–Tengah Line. LTA has named the catchments and started engineering studies, but has published no alignment and no station list. The stations drawn are this analysis’s reading of those catchments.
- Dotted lines — entirely speculative. Only the Paya Lebar Air Base corridor, inferred because 150,000 homes on 800 ha cannot meet the government’s own 10-minute-walk target on a single edge station.
- Bubbles — the Demand Gap Index,
DGI = H × A × T × C: homes needing service, times the access gap, times the timing gap, times a crowding multiplier. Orange is unmet need; green means the analysis expects nothing new, because rail is already there.
Click any station, line, or bubble to see why it is on the map: the reasoning, the numbered findings, and every source behind them, graded A (primary government) to D (unclear provenance).
Built from “Where Singapore’s Next MRT Lines Could Go” v2.0 (16 September 2026), an independent analysis by Claude. Sections 1–4 are sourced; the index, the forecasts and the speculative corridors are the author’s own model. Nothing here is LTA, MOT, URA or HDB policy. Station coordinates are approximate and the coastline is schematic.
