Recently, the world’s first high-speed commercial train with a speed of 350 kilometers per hour officially rolled off the assembly line in Tangshan, Hebei.
Compared with ordinary passenger sports cars, this high-speed cargo sports car with a Chinese sturgeon bone bionic front and a silver-white-red three-color penetrating body have a significant difference in the appearance-each car has a side surface. There is a set of loading doors with a width of 2.9 meters and the largest opening in the world for convenient cargo loading.
According to CRRC, the high-speed freight sports car group has 4 advantages:
First, it has broken through the key technology of rapid rail transit freight:
The high-speed freight train unit is based on the 350 kilometers per hour high-speed EMU platform in my country. It has broken through a number of key technologies for fast transportation of rail transportation such as carrying systems, running systems, intelligent loading and unloading tools, and fast loading and unloading.
A full range of loading and unloading equipment such as doors, standard container pedigree products, and modular freight floor, significantly improves the efficiency of loading and unloading operations and realizes large load, large volume, fast loading and unloading, and cargo in transit management.
The second is to meet the needs of medium and long-distance fast freight:
The high-speed freight trains use technologies such as big data analysis, cloud virtual stowage, precise weight control, and genetic algorithms to realize the intelligent stowage of goods and the reasonable distribution of vehicle loads.
Using UWB technology, mobile data network, and Beidou satellite navigation technology, the precise identification and positioning of cargo and the interaction of cargo information between vehicles is realized.
It meets the needs of medium- and long-distance fast freight at a distance of 600-1500 kilometers, with significant advantages such as high transportation timeliness, high operating frequency, low transportation cost, and all-weather operation.
It is the first time in the world to achieve high-speed rail freight transportation at a speed of 350 kilometers per hour, significantly improving my country’s rail transportation equipment The level of independent innovation.
The third is safety and environmental protection:
The outer skin of the high-speed cargo sports car set adopts environmentally friendly water-based paint that green, environmentally friendly, non-irritating, non-polluting, and has no harm to the human body and the environment during long-term application.
The surface is delicate, beautiful, high in hardness, and easy to clean. The EMU is equipped with an intelligent fire alarm system, applying a variety of new fire-retardant materials and technologies.
The warehouse area uses a new intumescent fire-retardant coating, and the fire-proof layer has a service life of more than 10 years.
Fourth, environmental adaptability and operating economy have been significantly improved:
The 350 km/h high-speed cargo sports car set adapts to the ambient temperature-25°C to 40°C, the power configuration is 4 motor 4 tows 8 vehicles, the load is not less than 110t, the cargo volume is not less than 800m³, the cargo space utilization rate is ≥85%.
Compared with air and road transportation, the freight vehicle group is less affected by environmental factors and can be reached within 5 hours at a distance of 1,500 kilometers.
The front of the EMU adopts the bionic design of the Chinese sturgeon skeleton line, which increases the slenderness ratio of the front. The wind tunnel test proves that the head is dynamic and beautiful, and it greatly reduces the running resistance compared with the existing models. Energy consumption by weight is only 8% of aircraft.
