China: The tests took place in January in one of China’s coldest regions, Hulunbuir.
Traction lithium-ion batteries of two prototype FXD3H shunting locomotives operated for 24 hours straight at temperatures ranging from -30 °C to -42 °C. The locos successfully completed ten test runs.
Since August 2023, the 2.2 MW locomotives have undergone testing in various climatic zones of China. According to CRRC, they are 10% more efficient than similar shunting diesel locomotives in terms of traction performance. The locomotives are equipped with a battery monitoring system and have a modular design that is also used in other Fuxing vehicles, such as the FXN3D hybrid locomotives.
In 2022, the pilot batch of hybrid locomotives of the previous generation entered service, while the very next year the company produced the four-axle CHA3C1 for a steel plant in Nanjing.
