Core Insights - The article highlights the advantages of rail-sea intermodal transport, emphasizing its cost-effectiveness and efficiency compared to traditional road transport, particularly for distances over 600 kilometers [1][2]. Group 1: Cost and Efficiency - Rail-sea intermodal transport can save approximately 30% in transportation costs compared to road transport for distances over 600 kilometers [1]. - From January to May, the national railway sent a total of 6.833 million TEUs (Twenty-foot Equivalent Units) of rail-sea intermodal cargo, marking an 18.4% year-on-year increase [1]. - The rail-sea intermodal service from Zhengzhou to Qingdao significantly reduces transit time by nearly 50% for exports compared to road transport [2]. Group 2: Infrastructure and Operations - The establishment of shared terminal facilities and the "front port and back station" model has improved operational efficiency and reduced transfer costs [3][5]. - Ningbo-Zhoushan Port has implemented a shared terminal model, which has increased the daily handling capacity to 3,200 TEUs, more than doubling operational efficiency [4]. - By the end of last year, Ningbo-Zhoushan Port had built 38 inland dry ports, while Qingdao Port had 51, enhancing the intermodal network [8]. Group 3: Innovations in Logistics - The "one box" system allows for seamless transport without changing containers, significantly reducing logistics costs and transit times [6][9]. - The "one box" system has cut the transport time for African copper concentrate from 15 days to 6 days, with a 10% reduction in logistics costs [9]. - The "Iron-Sea Express + Middle East Fast Shipping" model has reduced the shipping time from Yiwu to Dubai from 23 days to 17 days, lowering logistics costs by 18% [9].
