The Circular line (; also known as Yellow line) is a medium-capacity rapid transit line on the Taipei Metro. The first section of this line is operated by New Taipei Metro Corporation and it runs between and in the Taipei metropolitan area. It is approximately long with 14 stations. The initial western section was opened on 31 January 2020. Hitachi Rail Italy supplied 17 sets of 4-car driverless medium-capacity trains for the line. Extensions are currently underway to form a full loop.
Construction
Hitachi Rail STS supplied electromechanical equipment for the line, including driverless technology and CBTC signaling.
Construction for the first phase officially broke ground on 11 July 2011 on a elevated section between Zhonghe and Banqiao. The section is estimated to cost NT$13.7 billion, with the entire first-stage route estimated to cost NT$54.7 billion to construct.
The line includes the first elevated split platforms in the system at , , and due to the narrowness of the available station area.
The initial section between and opened on 31 January 2020. with the fare structure still integrated with the Taipei Metro system, unlike light rail lines of the New Taipei Metro.
Public art
Unlike previous public art installations on the metro, it was decided that a smaller number of art pieces would be installed within the same budget, allowing for large-scale artwork.
Across the above ground section of the line, Emmanuelle Moureaux (a Tokyo based French architect and designer) spread distinctive bold colours across infrastructure – including steel beams and pillars, noise barriers, 13 stations and platforms, a bridge over the Tamsui River, and the exterior and interior design of the train.
The platforms, walls and ceilings of Banqiao station are decorated by French artist Daniel Buren, using regular, contrasting coloured stripes.
Stations
The western section of the line officially opened on 31 January 2020. Services between Zhonghe and Banqiao were temporarily suspended from 3 April 2024 onwards due to the 2024 Hualien earthquake, with the repair work expected to take one year to complete. The section reopened ahead of schedule on 12 December 2024 at 12:00 PM Taiwan Standard Time.
