Shanghai bets on rail and data to bind Yangtze River Delta closer together

by ZHUANG Jian

From cross-provincial commuter railways to shared autonomous-driving data, Shanghai is pushing to turn the Yangtze River Delta into a more seamless economic region, as officials prepare the next phase of China's regional integration drive.

At a construction site in Shanghai's Songjiang district near the borders of Jiangsu and Zhejiang provinces, cranes rise above Shuixiang Keting Station, a future hub on the Shanghai-Suzhou-Jiaxing intercity railway.

The underground station, more than one kilometer long, will connect five rail lines and serve as the core node of the 170km railway linking Shanghai, Suzhou and Jiaxing.

Construction on the railway began in 2022 and operations are scheduled to begin in 2028.

The project is one of the flagship infrastructure schemes under China's Yangtze River Delta integration strategy, elevated to national strategy status in 2018. The region — comprising Shanghai, Jiangsu, Zhejiang and Anhui — accounts for nearly a quarter of China's economic output and includes 10 cities with GDP above 1 trillion yuan.

The railway consists of three sections funded separately by local governments: Shanghai's Demonstration Zone Line, Jiangsu's Water Town Tourism Line, and Zhejiang's Jiashan-Xitang and Jiaxing-Fengnan lines.

Their convergence point is Shuixiang Keting Station.

The commuter-style rail system sits between metro networks and high-speed rail, with metro-style boarding and no assigned seating. Speeds of 160-200 kilometers per hour allow the lines to function as rapid intercity links.

Once operational, the Shanghai-Suzhou-Jiaxing line will cut travel time from Shuixiang Keting Station to Hongqiao transport hub to about 30 minutes. From Hongqiao, passengers will be able to reach Suzhou or Jiaxing in under an hour.

Officials say the line is intended to accelerate the movement of people, technology and capital across one of China's most economically important regions.

But the bigger challenge may lie in operating the railway across provincial boundaries.

The annual Yangtze River Delta leadership meeting, scheduled to be held in Shanghai on May 20-21, is expected to focus on regional integration priorities under China's 15th Five-Year Plan. Cross-provincial rail coordination is likely to feature prominently in those discussions.

In late 2024, state-owned firms from Shanghai, Jiangsu and Zhejiang jointly established a regional rail operating company to oversee dispatching, fare clearing and cost-sharing across rail networks around Shanghai.

XU Ganfeng, chairman of the company, told Jiemian News the long-term goal was to create a metro-like travel experience across the Yangtze River Delta.

Passengers boarding trains in Kunshan or Pinghu, he said, should eventually notice little difference from riding the Shanghai metro.

The dispatch center is designed to eventually manage up to 1,200km of rail lines and serve as the operational brain of the region's future rail network. The first cross-provincial railway could join the system by the end of 2028.

Before that can happen, local governments and rail operators still need to negotiate unified standards for ticketing, dispatching and cost-sharing.

Officials acknowledge that seamless cross-provincial travel will require local governments to give up a degree of administrative fragmentation.

Xu said unified dispatching would improve efficiency and lower costs by allowing trains and resources to be allocated across the broader network rather than managed separately by individual jurisdictions.

"How far integration can go depends on how much reform local governments are willing to embrace," Xu said.

Officials point to the region's environmental coordination system as a possible model for broader regional governance.

The Yangtze River Delta already operates a shared air-quality monitoring system covering 41 cities and more than 3,000 monitoring stations. Shanghai serves as the central data hub, while coordinated pollution-control responses have become routine across the region.

Regional coordination is also extending into autonomous driving. Shanghai and Suzhou now share intelligent vehicle testing systems and regulatory data, following a 2019 agreement among Shanghai, Jiangsu, Zhejiang and Anhui to mutually recognize testing permits.

Regional integration is also extending into scientific research and industrial coordination. Shanghai, Jiangsu, Zhejiang and Anhui are preparing to jointly launch a regional basic research fund, while companies from neighboring provinces are increasingly establishing research operations in Shanghai to access talent and technology resources.

China's newly released 15th Five-Year Plan outline identified deeper integration of industrial chains, infrastructure and environmental governance in the Yangtze River Delta as a major national priority.

If successful, officials hope residents travelling across Shanghai, Jiangsu and Zhejiang may eventually experience the region less as separate jurisdictions and more as a single metropolitan economy.
