Kuala Lumpur never had to retrofit metro automation — it specified it from the start, twice more after 1998. The MRT Kajang line opened its first phase in December 2016 and its full 51 km in July 2017, running driverless on Bombardier's CITYFLO 650 CBTC. The MRT Putrajaya line followed, opening a first phase in June 2022 and the full route on 16 March 2023: 57.7 km and 36 stations, 13.5 km of it underground beneath the city centre with nine below-ground stations. Trains carry no driver; a manual control stand sits behind a locked panel at the head of each train for recovery moves. Both lines are regional spines — Kajang and Putrajaya lie outside the capital — but the tunnelled core threads Kuala Lumpur itself.
what does this mean?
The strongest source is press reporting; no primary evaluation was located. It grades who did the looking — not how well the project went. All four grades →🎓 Lesson
The grammar test for driverless metros asks for the date when nobody is on board any more. For Kuala Lumpur's MRT lines the answer is the opening day — the rarer case where full automation was the procurement baseline, not a later promotion.
