The launch of an MRT line connecting Taiwan Taoyuan International Airport and the greater Taipei area has been postponed again as the contractor has failed to meet the specified standards during testing, the Bureau of High Speed Rail said.
The Ministry of Transportation and Communications (MOTC) is scheduled to make a formal announcement on the status of the project next week, bureau Director-General Allen Hu (胡湘麟) said.
At the end of last year, the ministry announced the line would launch next month. A failure to meet that deadline would be the sixth time that the ministry has had to postpone the launch of the system.

The contractors failed in three key areas, the bureau said.
First, the contractors are contractually obliged to ensure that the average operating speed is 60kph for the express train service and 45kph for the regular train service, the bureau said.
However, testing revealed that the express train service was running at an average speed of between 57kph and 58kph, while the regular train service only achieved an average speed of between 41kph and 42kph.
Second, express trains from Taipei Railway Station must make the journey to Taoyuan airport’s Terminal One within 35 minutes, but tests showed the trip was taking trains between 35 minutes, 50 seconds, and 37 minutes.
Third, although the signaling system must be able to dispatch the trains at intervals of three minutes, trains are being deployed at intervals of between 3 minutes, 15 seconds and 3 minutes, 17 seconds.
The contractor needs to tweak the software of the signaling system to overcome these obstacles, MRT engineering office acting director Tsao Le-chun (曹樂群) said, adding that failing to address these problems would affect the quality and reliability of the service offered by the system.
The contractor and subcontractor have not found solutions to these issues, the bureau said.
The system is slated to undergo operational testing in 46 specific areas, Tsao said, with six as yet untested.
Before the bureau can apply for an initial inspection from the MOTC, the Rules of MRT Final Inspection and Testing for Revenue Service state that the system must undergo reliability tests for at least seven consecutive days, with system availability reaching a threshold of 90 percent, Tsao said.
Taoyuan Metro Corp — which is to be in charge of operating the system — has said it needs three more months to conduct drills before the system can be launched.
The new line is 51.03km long and incorporates 22 stations en route. The route passes by or through New Taipei City, Taoyuan, Sinchuang (新莊), Sanchung (三重), Linkou (林口), Gueishan (龜山) and Jhungli (中壢).
UPGRADE: The Kang Ding-class frigate is replacing its Chaparall missiles with Tien Chien II and Hua Yang VLS, which would provide it with long-range, 360° air defense Taiwan plans to produce 1,200 to 1,376 Hai Chien II missiles (海劍二, Sea Sword II) — also known as TC-2N — to serve as the standard air defense system of the navy’s surface combatant fleet, a source said yesterday. Last week, the Hai Chien II, the naval version of the Tien Kung II missile (天劍二, Sky Sword II), completed a live-fire test in waters off the National Chungshan Institute of Science and Technology’s Jiupeng facility (九鵬) in Pingtung County’s Manjhou Township (滿州). The MIM72 Chaparral and other dated air defense missiles that currently arm Taiwanese ships have inadequate range to combat Chinese
REASONS FOR TRAVEL: An assistant professor said that proposed amendments to penalize drivers if they used drugs overseas would not deter people from traveling People who operate a motor vehicle under the influence of marijuana would have their driver’s license revoked, even if they used the substance while overseas, the Ministry of Transportation and Communications said yesterday, citing proposed amendments to the Road Traffic Management and Penalty Act (道路交通管理處罰條例). The amendments would also authorize the government to revoke the licenses of people determined to have used Category 1 or Category 2 narcotics, even if they were not operating a vehicle while under the influence of drugs, as well as ban them from taking the license test for three years, the ministry said. People aged 18 or
Shih Hsin University President Chen Ching-he (陳清河) yesterday issued a public apology for comments made in his commencement speech last week, stating that he has asked the school to suspend his duties and halt his wages for two months as a show of contrition. At the commencement ceremony on May 30, Chen said, “If you don’t manage your time well, or your own emotions, or your health, then I am telling every one of you — put a quick end to ‘you,’ because the world has no need for ‘you.’” The comments have sparked significant controversy online, and Chen through an open
Johanne Liou (劉喬安), a Taiwanese woman who shot to unwanted fame during the Sunflower movement protests in 2014, returned to Taiwan last night after being deported from the US. She is to stand trial in Taiwan for charges involving embezzlement, fraud and drug crimes. The Criminal Investigation Bureau (CIB) said it took her into custody at Taiwan Taoyuan International Airport and would first question her before transferring her to the New Taipei District Prosecutors’ Office. She was arrested upon disembarking a flight from San Francisco that landed shortly before 7pm. Liou absconded to the US in 2019 after jumping bail
