New Taipei’s long-awaited Sanying Line, a fully automated light blue metro corridor, entered service on June 30, introducing a new driverless link between western Taipei and the fast-growing districts of Sanxia and Yingge.

New Automated Link for Western Greater Taipei

The Sanying Line is a 14.29 kilometer elevated metro route running from Dingpu, the western terminus of Taipei Metro’s Bannan (Blue) Line, through Tucheng, Sanxia and Yingge in New Taipei. Publicly available information shows that the new line adds 12 medium-capacity stations to the region’s rail network, many of them in areas that previously relied heavily on buses and road traffic.

The corridor is branded as the Light Blue Line within the Greater Taipei map, visually tying it into the existing rapid transit grid while remaining under the operation of New Taipei Metro. Reports indicate that passengers can transfer directly to the Taipei Metro network at Dingpu and to conventional rail services at Yingge Station, positioning the line as a new cross-regional spine on the western side of the metropolis.

Service launched in the early afternoon of June 30, following a period of trial operations and final inspections that concluded in June. According to published coverage in Taiwan-based outlets, the opening came after earlier projections that the project would be completed by late 2025 and begin passenger service in 2026.

The Sanying Line joins the Circular Line and light rail corridors such as Danhai and Ankeng in New Taipei’s growing portfolio of automated rail projects, marking another step in the gradual expansion of driverless operations across northern Taiwan’s transit systems.

Fully Driverless Operation and System Design

The new line operates as a fully automated metro, using a driverless train control system and platform screen doors at stations. Earlier technical briefings and public planning documents describe the route as a medium-capacity system using two-car trainsets, similar in concept to the rolling stock on New Taipei’s Circular Line but adapted for the Sanying corridor’s demand and station layouts.

Automation allows the operator to run trains at relatively short headways with centralized supervision, while platform screen doors are intended to improve safety and climate control on elevated platforms. According to engineering information released in recent years, the line employs modern communications-based train control and a dedicated operations control center located within New Taipei.

The fully elevated alignment minimizes conflicts with road traffic and reduces the need for level crossings. Columns and viaducts follow existing road corridors and riverbanks where possible, an approach that has become common in Taiwan’s recent metro extensions to manage both cost and construction disruption.

By opting for a medium-capacity, automated configuration rather than a full heavy metro, planners have aimed to balance capacity with the lower densities found in parts of western New Taipei, while still providing a rapid, high-frequency service that integrates with the broader metro and railway network.

Free Rides and Early Passenger Response

To mark the launch, New Taipei has introduced a period of free rides on the Sanying Line, with published coverage indicating that fares are waived through the end of August. The initiative is intended to encourage residents and visitors to sample the new service, test transfers and explore destinations along the route.

Early reports from local media and transit-focused communities highlight brisk interest from commuters, students and rail enthusiasts on opening day, with many riders boarding at Dingpu to experience the new automated journey through Tucheng, Sanxia and Yingge. The free-ride window is expected to give the operator additional time to fine-tune operations under real-world passenger loads.

Transit observers note that northern Taiwan has often coupled new metro openings with promotional fare policies, using them to build familiarity with new routes and to shift habitual road users toward rail. The Sanying Line’s introductory offer follows this pattern, potentially accelerating ridership growth during the initial months of operation.

The rollout is also being watched closely by residents of communities slated to benefit from future extensions, who are looking to the first phase of Sanying service as a preview of how expanded rail access might reshape local mobility and development patterns.

Tourism Access to Sanxia, Yingge and the Art Museum

Beyond commuting, the Sanying Line is being positioned as a new gateway to several of New Taipei’s best-known cultural and leisure destinations. The route serves the New Taipei City Art Museum, a major contemporary arts venue on the banks of the Dahan River, as well as Yingge’s historic ceramics district, renowned for its pottery studios and shops.

Coverage by local outlets emphasizes that visitors can now travel directly from Taipei’s Blue Line terminus at Dingpu to these attractions without relying on long bus rides or private vehicles. This is expected to shorten travel times for weekend visitors and international tourists staying in central Taipei who are interested in day trips to the western suburbs.

Sanxia’s old street, traditional temples and riverside parks also fall within the line’s catchment, giving the corridor a tourism profile that extends beyond routine commuting. City promotional materials and transport network maps have begun to highlight Sanying stations as jumping-off points for walking routes, heritage sites and riverside cycling paths.

Tourism analysts quoted in past coverage of the project have pointed to the experience of other Taiwanese metro lines, where improved rail access has spurred new cafes, small hotels and cultural events around stations. Observers will be watching whether similar patterns emerge in Sanxia and Yingge as the line settles into regular operation.

Future Extensions and Regional Integration

The Sanying Line now forms part of a larger strategy to knit together Taipei, New Taipei and Taoyuan via interconnected metro and railway services. Planning documents circulated by New Taipei authorities and national transport agencies describe a long-term goal of extending the Sanying corridor toward Taoyuan’s Green Line and, eventually, enabling smoother transfers to Taoyuan International Airport.

Such connections would, over time, create an arc of automated and conventional rail lines spanning the western side of the greater metropolitan area, offering alternatives to congested expressways for both daily commuters and airport-bound travelers. The initial Sanying segment is therefore viewed as a foundational piece of a broader regional network.

The project has also been discussed as a tool for shaping more balanced urban growth. By pairing new stations with zoning changes, public spaces and pedestrian improvements, New Taipei aims to focus development along rail corridors while preserving other areas from uncontrolled sprawl. The Sanying Line’s elevated stations and surrounding plazas are expected to become focal points for this form of transit-oriented development.

With the line now open to passengers, attention is turning to performance indicators such as daily ridership, on-time operation and transfer volumes at Dingpu and Yingge. These metrics are likely to inform future decisions on service frequency, station area upgrades and the timing and scope of planned extensions toward Taoyuan and other western districts.
