Taichung's Green Line subway has broken down seven times in under eight months, and city councillors say safety and repair times are getting worse, not better.

• Signal system faults, platform door failures, power trips and train breakdowns have all hit the line since late last year.
• One stretch in June saw two separate failures inside 48 hours.
• Most breakdowns happen at rush hour, when trains are packed and delays hit the most people.
• An audit found high-risk emergency repair calls rose in 2025, with average repair time jumping from about four hours to over six — a sign the faults are getting harder to fix.
• Riders complain they are left with no information during a breakdown, unsure whether to get off, and stranded with no replacement transport.

Outlook: The operator says it is working with the original equipment maker on inspections and a system restart, but with no fix timeline, more rush-hour disruptions look likely.
