on september 24, local time, the hydrogen energy city train and city c-type train developed by crrc changke co., ltd. were unveiled at the 2024 international rail transit technology exhibition (innotrans) in berlin, germany, and received widespread attention from the audience.

the international rail transit technology exhibition in berlin, germany is the largest and most influential industry exhibition in the global rail transit field, and is known as the "olympics" of the rail transit industry. with the theme of the future of mobility, this exhibition has 42 exhibition halls and 3.5 kilometers of outdoor display track. the total exhibition area exceeds 200,000 square meters. the number of exhibitors exceeds 3,000 and the number of visitors is expected to exceed 180,000. . with the theme of "towards a low-carbon future", crrc debuted with a number of star products and a number of advanced technologies.

a new model of green energy saving—hydrogen energy urban train

in march this year, my country's first hydrogen energy urban train conducted a 160km/h full-load operation test on the test line. for the first time, the full-system, full-scenario, and multi-level performance verification of a hydrogen-energy train was achieved, marking an achievement in the application of hydrogen energy in the field of rail transportation. a new breakthrough. at this exhibition, crrc demonstrated the technical characteristics of hydrogen energy urban trains to the world through an intelligent interactive system.

according to wang jian, deputy director of the new technology research department of the crrc changke national rail passenger vehicle engineering research center, the train has a built-in hydrogen power system to provide a strong and long-lasting power source for vehicle operation. the train applies a multi-energy storage and multi-hydrogen energy system distributed hybrid power supply solution. it also adopts the hydrogen-electric hybrid energy management strategy and control system independently developed by crrc changke, achieving deep integration of the entire vehicle control and greatly improving the efficiency of the train. it improves energy utilization efficiency while improving the flexibility and reliability of energy supply.

hydrogen energy urban transportation has the advantages of cleanliness, environmental protection, simple operation and maintenance, short construction period, and low fixed investment. it has the characteristics of high speed, large transportation volume, fast boarding and landing, safety and intelligence, etc., which perfectly meets the needs of urban transportation.

intelligent travel with smart appearance - urban c-type train

the urban c-train with a smart curved appearance is particularly eye-catching at the exhibition. "urban c-type trains have the characteristics of high speed, large passenger capacity, high level of intelligence, safety and comfort. the train has a maximum operating speed of 160km/h, and a maximum capacity of 2,180 passengers in an 8-car train. it realizes the integration of high-speed rail technology and urban rail transit operations. the perfect combination of modes has broad application prospects in the field of urban rail transit," said yin hang, senior engineer of crrc changke co., ltd.

the urban c-type train is developed based on the high-speed rail technology platform. it continues the high-speed rail technology solution in terms of sound insulation, noise reduction and air-tightness performance, and combines the characteristics of public transportation operations to optimize performance. the vehicles adopt cutting-edge technologies such as intelligent travel services, intelligent monitoring, intelligent operation and maintenance, and intelligent driving, and provide considerate intelligent services such as lighting adjustment, pressure wave intelligent adjustment, and wireless charging, improving the intelligence level of urban railway vehicles.

the train has the conditions for interconnection with main line railways, effectively connecting main line railways and urban rail transit networks, and providing convenient travel methods. at the same time, for the first time, the vehicle length design of the head car and middle car is adopted, which can realize 4-car grouping and 4+4 flexible marshalling forms such as heavy-duty marshalling and fixed 8-vehicle marshalling can meet customized operation needs.
