The Tengah Line (tentative name) is a future rapid transit line currently under feasibility studies.
Engineering studies for the Tengah Line (Phase 1) are planned to commence in 2026.
Committee of Supply Debate 2025
As part of the Ministry of Transport (MOT) Committee of Supply (COS) Debate 2025, it was revealed by the Land Transport Authority (LTA) that feasibility studies for a new line, tentatively called the Tengah Line, was currently ongoing.
