(Central News Agency, reporter Zhao Liyan, Taichung, June 3) The Taichung Metro Green Line experienced a power trip due to a signaling system anomaly on the morning of June 3, delaying trains across the entire line for about 21 minutes. The Democratic Progressive Party (DPP) caucus in the Taichung City Council stated that the Taichung Metro has malfunctioned four times in less than six months and demanded a thorough investigation into the causes and an explanation of the handling progress.

In a press release, Taichung Metro Corporation stated that at 7:23 a.m. on June 3, an anomaly occurred in a Smart Input/Output (SMIO) card at the Beitun Depot, causing a power trip on the third rail for both directions of the Green Line and the entire depot area, delaying train operations across the entire line. The issue was resolved at 7:44 a.m., and full-line operations resumed, with train intervals to be gradually adjusted.

Taichung Metro stated that the four malfunctions since December last year have different causes. The company has conducted repairs and equipment replacements responsibly, simultaneously obtaining failure cause analysis from the original manufacturer to review and optimize relevant contingency procedures to prevent similar occurrences.

The DPP caucus in the Taichung City Council stated in a press release that Taichung Metro experienced two consecutive malfunctions within three days at the end of last December, another malfunction on March 21 this year, and today's incident. These four malfunctions in less than six months have caused inconvenience for commuters and raised concerns about the safety of public transportation.

Caucus convener Chou Yung-hung pointed out that Taichung Metro has never clearly explained the causes of the malfunctions or proposed any fundamental solutions, only responding with 'under investigation' or 'case-by-case handling,' which fails to reassure the public.

Chou emphasized that as Taichung's most important rail transit system, stable operation is the most basic requirement. Taichung Metro must thoroughly investigate the causes of the malfunctions, explain why the backup protection mechanisms failed, propose concrete and feasible improvement plans and timelines, explain subsequent handling progress, and establish an information disclosure mechanism after malfunctions occur.
