en.Wedoany.com Reported - On May 20, train 81975/6, fully loaded with 30 container cars and 10 JSQ commercial vehicle wagons, departed from the Chongqing Xinglongchang Marshalling Station, traveling a total of 1,773 kilometers directly to Tongshan Station in Jiangsu Province and Dangjiazhuang Station in Shandong Province. This marks the first time the Chongqing Railway Logistics Center has achieved mixed-consist operation combining JSQ wagons (specialized transport vehicles for finished automobiles) and containers, signifying a new breakthrough in the "point-to-point" express freight train transportation organization model.

Previously, due to differences in vehicle type, load capacity, and braking parameters, JSQ wagons and containers typically had to be dispatched separately in batches, only departing once enough had accumulated to form a full train. This not only occupied yard resources but also extended the goods' transit time. The Chongqing Railway Logistics Center of China Railway Chengdu Bureau Group, in collaboration with Xinglongchang Station, tackled the problem by optimizing the marshalling plan and breaking through technical barriers, achieving mixed-consist operation of the two vehicle types for the first time, realizing "marshalling upon arrival and dispatch upon marshalling."

"In the past, automobiles and bulk cargo had to wait for separate trains. Now, they can be loaded onto a single train, so customers no longer need to consolidate shipments," said Liu Yushan, Freight Director of the Tuanjiecun Business Office of the Chongqing Railway Logistics Center. He explained that this mixed-consist operation has significantly reduced the assembly and waiting time for both JSQ wagons and containers, markedly shortening the overall transit time compared to previous similar sporadic dispatches.

To ensure the smooth operation of the first mixed-consist train, the Chongqing Railway Logistics Center joined forces with Xinglongchang Station and the Chengdu Branch of China Railway Special Cargo Services Co., Ltd. They coordinated the dispatch of empty containers and JSQ wagons, interfaced with customer dynamics in real-time to ascertain the supply readiness for the 30 container cars and 10 fuel-oil automobiles, optimized the loading operation process, and implemented a policy of "priority empty allocation, priority loading, and priority dispatch."

"Point-to-point" express freight trains are customized logistics products launched by the railway for stable cargo flows between large and medium-sized cities, operating on a "transit-like" model with fixed train numbers, fixed routes, and fixed schedules. This mixed-consist operation not only improves line utilization rates but also provides customers with more flexible and efficient transportation options. It is estimated that goods transported via this block train on the Chongqing-Xuzhou and Chongqing-Jinan routes see significant advantages in both comprehensive logistics costs and transit time compared to traditional methods.

Going forward, the railway authorities will gradually promote the JSQ wagon and container mixed-consist model based on market demand, increase the frequency of "point-to-point" express block trains, and further smooth the logistics channels connecting the western region with East China.
