Hubei launches first oil-to-electric new energy locomotive

By Chen Zai

Hubei Province has launched its first oil-to-electric new energy locomotive on the Songzi-Yidu Railway, marking a major step toward greener railway transport.

This newly converted locomotive, originally a diesel model, is equipped with 2300 kWh lithium iron phosphate batteries and delivers 2160 kW of power, capable of hauling up to 5000 tons on flat terrain. It can travel 150 kilometers on a single charge.
"Once covered in oil stains and coal dust after trips on diesel locomotives, my clothes now remain clean thanks to the improved working conditions," said Zhang Yuanchang, the train’s driver.

Since opening in 1975, the Songzi-Yichang Railway has been a vital transport lifeline for ore, coal, chemicals, and agricultural products, with an annual transport capacity of 5 million tons, however, the diesel locomotives had issues with noise, pollution and costs.

The new energy model addresses these issues by reducing carbon dioxide emissions by approximately 487 tons annually and cutting energy costs by 50 percent, supporting both environmental protection and operational savings.

In addition, the converted trains feature advanced control systems that can intelligently monitor various functions, such as traction force and battery status, enhancing operational safety and efficiency.

Within three years, all remaining diesel locomotives on the Songzi-Yidu Railway are expected to be converted, aiming for zero carbon emissions on the line.
