Taoyuan Metro Green Line northern section enters dynamic testing

桃園捷運綠線北段進入動態測試

TAIPEI (Taiwan News) — The northern section of the Taoyuan Metro Green Line, comprising seven stations, began dynamic testing on Wednesday as part of preparations for an expected opening by the end of the year, per CNA.

Dynamic testing is the final phase before passenger service, during which trains operate on newly built tracks under real-world conditions. The process evaluates interactions among trains, tracks, signaling, and power systems to ensure safety and performance.

Taoyuan Mayor Chang San-cheng (張善政) visited G15b Kengkou Station on Wednesday afternoon and rode a train with the construction team to review the status of trackside equipment installation and testing. He disembarked at G11 Arts and Culture Zone Station to inspect the construction of the underground station.

Chang said testing now covers all seven stations in the northern section, marking the start of a critical stage of the project. He stressed that safety would remain the top priority as testing and system integration continue to ensure full readiness for the line’s opening.

Taoyuan City Department of Rapid Transit Systems Director Liu Ching-feng (劉慶豐) said low-speed pretesting began in July, with train parameter calibration completed in December. He said the signaling system manufacturer has since taken over dynamic testing of the mainline.

Liu said substantial progress has been made in laying trackside cables, installing the third-rail power supply and completing static testing of trackside equipment. With all prerequisites met, trains are expected to undergo several months of dynamic testing starting Wednesday.

The Taoyuan City DORTS said the Green Line will use a fully automated (Grade of Automation 4), driverless system. Trains will be entirely controlled by the signaling system to comprehensively verify operational safety and emergency response capabilities.

As dynamic testing continues, key items to be checked include signal reception between trains and trackside equipment, driving mode switching, overspeed protection, and timetable verification.
