The Kelana Jaya line has run driverless since it opened in September 1998 as the PUTRA LRT — described at the time as the world's second-longest fully automated driverless metro, on Bombardier's linear-motor ART trains. The automation outlived its owner: the privately financed operator ran into severe financial difficulty, the government arranged a RM5.5 billion (about $1.4 billion) bond issue to buy the assets of PUTRA and the parallel STAR line, and state-owned Prasarana has owned and run the line since 2002. Later extended to Putra Heights, it now runs 46.4 km through 37 stations — among the longest driverless metro lines anywhere, threading the capital and crossing into Petaling Jaya and Subang Jaya. Its dependency showed in November 2022, when a recurring fault in the Thales-supplied automatic train control electronics closed 16 stations for seven days while engineers and the Canadian supplier searched for the cause.

🎓 Lesson

Automation was never the weak part. In 24 years the line's two crises were a balance sheet and a signalling cabinet — driverless operation proved easier to buy than the finances and electronics that keep it running.

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.

run driverless since it opened in September 1998 as the PUTRA LRT
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The trade profile dates section 1 to September 1998; the operator calls it the Klang Valley's first fully automated and driverless rail system.
Caveat
Neither source documents an on-board attendant phase; 'driverless from opening' is the operator's and trade press's description, and no source states the staffing arrangement of the first months.

What the mapping says
The profile states it became the world's second longest fully-automated driverless metro system.
Caveat
