Japan's Next-Generation Bullet Trains Head to Taiwan: What's New About the N700ST?

Taiwan’s west coast high-speed rail corridor—often described as the backbone of the nation’s “Silicon Island”—is undergoing its most significant rolling stock upgrade in nearly two decades. As passenger demand skyrockets beyond pre-pandemic records, Taiwan High Speed Rail Corporation (THSRC) is bringing next-generation Japanese bullet train technology to its network.

The first set of N700ST bullet trains—custom-built for Taiwan based on Japan’s flagship N700S Shinkansen—has officially rolled off the assembly line at Hitachi’s Kasado Works in Yamaguchi Prefecture. Here is a comprehensive look at why Taiwan invested in these trains, what makes the N700ST unique, and how it will transform regional travel.

1. Why This Matters: Soaring Demand on Taiwan’s Rail Backbone

Since its launch in 2007, the Taiwan High Speed Rail (THSR) network linking Taipei in the north to Kaohsiung in the south has served over 1.03 billion passenger trips. Daily passenger volume has grown more than fivefold since operations began, reflecting intense reliance on the high-speed line by business commuters, tourists, and tech sector professionals traveling across Taiwan’s major industrial hubs.

This rapid rise in ridership has pushed the current fleet toward peak capacity during weekends and holidays. To relieve bottlenecking without altering physical track infrastructure, THSRC required modern rolling stock capable of providing higher service frequency, lower energy consumption, and increased passenger throughput.

Capacity Expansion: Adding the new fleet will enable THSRC to scale its schedule from 1,134 weekly train services up to 1,400 services.
Peak Hour Relief: The addition of 12 new trainsets will boost peak-hour transport capacity by approximately 25%.
Economic Mobility: Fast, reliable connections directly support Taiwan’s Western Corridor economic engine, where high-tech and semiconductor industries have expanded exponentially over the past two decades.

2. What is the N700ST?

The N700ST (“ST” standing for Shinkansen Taiwan) is a customized, 12-car export variant of Central Japan Railway Company’s (JR Central) N700S (“Supreme”) Shinkansen, which entered service in Japan in July 2020.

While sharing the advanced core platform of its Japanese counterpart, the N700ST has been tailored specifically to operate under Taiwan’s climatic conditions, power systems, and passenger preferences.

3. Key Specifications

In May 2023, THSRC officially awarded the rolling stock contract worth approximately ¥124 billion (NT$28.5 billion) to the Hitachi-Toshiba Supreme Consortium (HTSC).

4. Why Taiwan Chose Japanese Shinkansen Technology

Taiwan’s decision to continue its partnership with Japanese high-speed rail manufacturers relies on a proven 20-year track record:

Unrivaled Safety Record: Operating since 2007, Taiwan High Speed Rail has logged over 1.03 billion trips with a zero passenger casualty record and an average operational punctuality rate exceeding 99.5%.
Infrastructure Compatibility: THSRC’s existing signaling systems, track gauge, overhead catenary power, and maintenance depots were built around Japanese high-speed rail standards (specifically the 700T series derived from the 700 Series Shinkansen). Adopting the N700S platform ensures seamless integration.
Earthquake Resilience: Japan’s Shinkansen technology is engineered specifically for active seismic zones—a critical requirement for Taiwan, which experiences frequent earthquake activity.

5. Passenger Benefits & Interior Upgrades

Beyond technical efficiency, the N700ST introduces several noticeable upgrades for daily passengers and long-distance travelers:

More Frequent Departures: Reduced wait times at stations thanks to the expanding weekly timetable (increasing to 1,400 trips per week).
Universal Power Access: AC power outlets are available at every seat across both Standard Class and Business Class carriages.
Rider Comfort: Fully active suspension systems work continuously to suppress lateral vibration, delivering a noticeably smoother ride at 300 km/h.
Modernized Displays: Interior cabins feature dual-tier, full-color LCD screens displaying real-time trip information, next-stop alerts, and safety notices.
Expanded Luggage Capacity: Reconfigured car interiors provide double-deck luggage racks to accommodate large suitcases.
Enhanced Accessibility: Dedicated family-friendly facilities, nursing rooms with washbasins, baby seats, and six dedicated wheelchair spaces equipped with restraint systems.

6. Advanced Technology & Engineering Highlights

The N700ST incorporates engineering solutions refined on Japan’s busiest high-speed line, the Tokaido Shinkansen:

Aerodynamic “Dual Supreme Wing” Design

The distinctive nose cone shape reduces air resistance and mitigates the severe pressure wave (“tunnel boom”) that occurs when entering tunnels at high speeds. This lowers external noise pollution and reduces cabin pressure fluctuations for passengers.

Energy-Saving Silicon Carbide (SiC) Power Electronics

The drive system utilizes silicon carbide (SiC) power devices combined with a blower-less cooling design. This layout makes the underfloor drive equipment smaller, significantly lighter, and roughly 7% more energy-efficient than older train generations.

Emergency Battery Self-Propulsion

Underfloor-mounted Toshiba SCiB™ lithium-ion batteries allow the train to self-propel at low speeds during power grid outages. In an emergency or natural disaster, the train can move itself out of tunnels or off elevated bridges to a safe evacuation point while keeping cabin lighting and restrooms functional.

7. Economic Impact Across Taiwan

The procurement of the N700ST fleet represents a strategic infrastructure investment valued at ¥124 billion.

Industrial Logistics: By connecting Taiwan’s northern political capital (Taipei) with southern tech manufacturing hubs (Hsinchu, Tainan, Kaohsiung), faster and more frequent services support high-tech supply chains.
Tourism & Regional Business: Increased seat availability during peak travel periods will boost domestic tourism and business travel, ensuring reliable transit between major metropolitan areas.

9. Comparing Old vs. New: 700T vs. N700ST

Taiwan’s current high-speed fleet consists of 34 sets of the 700T series, which were manufactured between 2004 and 2015 based on technology from the late 1990s. Here is how the new fleet compares:

Feature	Existing 700T Fleet	Next-Gen N700ST Fleet
Base Platform	700 Series Shinkansen (1990s technology)	N700S Series “Supreme” (2020s technology)
Power Semiconductors	Silicon GTO/IGBT inverters	Compact Silicon Carbide (SiC) devices
Emergency Power	Auxiliary battery for essential lights only	SCiB™ battery self-propulsion out of dangerous zones
Power Outlets	Limited outlets in Business Class	AC power outlets at every passenger seat
Passenger Information	Single-color LED scrolling displays	Full-color dual LCD information screens
Ride Control	Semi-active suspension system	Fully active suspension & advanced damping control

10. Future Outlook for Taiwan’s Rail Transport

The introduction of the N700ST fleet forms part of Taiwan’s broader long-term transportation master plan. As the new trains enter service, THSRC plans a comprehensive revision of its timetable to optimize express vs. local high-speed services.

Furthermore, Taiwanese transport authorities are evaluating official proposals to extend the high-speed rail line further north to Yilan and further south to Pingtung. The added capacity provided by the 144 new N700ST carriages ensures that the network has the operational bandwidth required to support these future territorial expansions over the next decade.
