In order to provide a superior experience for passengers compared to traditional trains, CRRC also wanted to incorporate cutting-edge technologies as part of their offering, such as autonomous driving, intelligent passenger information systems (PIS) and 5G high-capacity train-to-ground communication.
Solution:
To overcome the demands of the project, HUBER+SUHNER were called upon due to its extensive experience of proven, customisable solutions within the rail sector.
A bespoke harness was provided not only to meet the specific requirements of CRRC but also to ensure the train was compliant with the safety standards expected of rail braking systems. The electrical and passenger information systems on the train were also enhanced through the use of innovative RADOX® 3 GKW and 4 GKW and TENIUS cables, to maintain reliable and stable signal transmission and electrical connections between the hydrogen power system and the other relevant sub-systems. These cables also helped to reduce weight and save crucial space within the train, which was a key requirement from the customer.
To further optimise communications, HUBER+SUHNER supplied two SENCITY® Rail MULTI 7-Port antennas for the train’s PIS and Wi-Fi system, alongside a SPUMA Radio Frequency (RF) cable with technical indicators to enable multi-network integration and accurate data analysis. These will help to assess the status of the train, improving the safety and efficiency of the service.
Result:
Thanks to the innovative solutions provided to the project, the world’s first hydrogen powered, 160km/h inter-city train was successfully rolled out in Chengdu in December 2022.
The train is equipped with a 4-car configuration and can reach a maximum speed of 160 km/h, the fastest train powered by hydrogen at the moment. With a built-in power system capable of up to a range of 600 km on a single charge, the combination of this technology alongside a super capacitor improves upon the catenary power supply traditionally utilised in trains.
With energy being generated through the electrochemical reaction of oxygen and hydrogen in the fuel cell, no nitrogen is emitted, and water is the only by-product. Consequently, commuters within Chengdu can now rely on an eco-friendly service that aligns with the government’s environmental aims.
HUBER+SUHNER were delighted to partner with CRRC and its key system suppliers, and will continue to supply high performance cable, antenna, and harness technologies that ensure fast, stable, and reliable connectivity. While the project was developed solely to provide a new solution for the Chinese inter-city railway market, we expect hydrogen powered trains will soon play a vital role in modern railway networks across the globe.
