Grain‑transport Rail Link in China’s Sanjiang Plain Completes Full‑scale Track Renewal

On 31 August, main‑line rail replacement and station‑track overhaul works on the Youyi‑Baoqing Railway in Heilongjiang Province reached practical completion. Designed by the 5th Survey and Design Institute under China Railway Construction Corporation and constructed by China Railway 22nd Bureau Group, the vital grain‑carrying corridor across the Sanjiang Plain undergoes comprehensive upgrading. The improvements address capacity bottlenecks for north‑to‑south grain shipments, optimise national grain‑circulation arrangements and deliver robust transport backing for domestic food security.

The Sanjiang Plain forms a core protected zone for China’s black‑soil farmland, ranking among the country’s most stable national‑level commodity‑grain bases with high volumes of marketable grain surpluses. Vast black‑soil farmlands produce large volumes of soybeans, maize and rice. Annual output and outward shipment volumes consistently sit among the highest nationwide, performing a critical role in safeguarding national food supplies.

Opened to traffic in 1998, the roughly 60‑kilometre Youyi‑Baoqing Railway runs through multiple key grain‑producing zones within the Sanjiang Plain and connects major commodity‑grain bases to consumer markets across the country. Full‑scale construction for this upgrade scheme got underway on 17 July. Site teams maintained parallel arrangements for freight operations and engineering work. Grain‑transport services remained uninterrupted throughout the works, while track structures received full reinforcement and station‑yard layouts underwent systematic optimisation.

Post‑renewal, the railway achieves tangible improvements in operational safety, freight throughput and maintenance standards. Bulk grain‑handling capacity rises substantially, matching outward‑shipping requirements generated by growing grain yields across the Sanjiang Plain. After nearly three decades in service, the revitalised grain artery maintains unobstructed north‑to‑south grain‑logistics routes.

Further freight‑volume tests will unfold along the upgraded line. Operational parameters will keep adjusting to accommodate seasonal grain‑shipping peaks, as the renovated infrastructure handles growing volumes of staple produce moving out from north‑eastern grain‑producing regions.
