China Tests Wireless Linked Freight Trains
China recently tested a new technology that allows seven freight trains to run together without being physically connected.
This wireless system helps the trains stay close to each other and move in sync, which can make moving large amounts of goods faster and more efficient.
The test was successful, with the trains maintaining a safe distance and speed.
This technology could help China move even more freight in the future without needing to build new train tracks.
China is already a leader in railway freight, and this new system could make it even better.
China successfully tested a wireless system to link seven freight trains without physical coupling.
The trains maintained a distance of 1091 metres and synchronized acceleration and braking at 60 kmph.
The technology was developed by China Shenhua Energy, a subsidiary of state-owned CHN Energy.
This system could increase freight loading capacity by up to 50 percent without additional infrastructure.
China's railway system transported over 2.33 billion tonnes of cargo in the first seven months of 2025.
