Good news in 2022: “Made in Ziyang” High-Power Hybrid Locomotive HXN6 Received Commercial Sales Orders

Hybrid Locomotive is a representative of CRRC Ziyang to implement the national dual carbon strategy.

As the earliest enterprise in China to develop hybrid locomotives, CRRC Ziyang took the lead in breaking through many problems such as energy control technology, and the integration of hybrid locomotives recognised by the industry. The company also fully mastered the core technology with independent intellectual property rights. The locomotives also include high voltage, large-capacity, high-current power battery grouping and modular technology, high-current charging and discharging safety control technology for power battery packs, and braking energy recovery control technology. Additionally, the company took the lead in formulating six design specifications including national railway power battery safety designs, battery management systems, and battery thermal protection. CRRC Ziyang has become a leading enterprise in the development of hybrid power locomotives.

In August 2020, with the support of the National Railway Group, the HXN6 hybrid locomotive, independently developed by CRRC Ziyang, became the first approved hybrid locomotive in the country. It carries the world’s largest electricity power, obtained through the Railway Locomotive and Rolling Stock Type Certificate and the Railway Locomotive Rolling Stock Manufacture License, issued by the National Railway Administration,

The effect of energy saving, emission reduction, and noise reduction is very significant, which is an important feature of hybrid locomotives. Since the power source of the locomotive is composed of a power battery pack and a diesel generator set, and the power battery pack is given priority to provide power under the condition of charging, the locomotive can reduce fuel consumption by more than 90% and reduce harmful emissions by 60% to 80%. At the same time, the locomotive also has many advantages such as saving locomotive brake shoes, quick start and acceleration, strong dynamic braking during operation, and low noise and environmental pollution. It is a green locomotive that can effectively replace traditional diesel locomotives.

This signed contract for the HXN6 locomotive also includes a water-cooled system for the power battery, an intelligent operation and maintenance system, optimised appearance and colour of the locomotive, standardised wiring and piping arrangements, and an improved level of engineering and intelligence. The energy saving and environmental protection performance of locomotives will be further improved with additional upgrades and new developments for the diesel engines.

At present, CRRC Ziyang has established a technology and product platform for Hybrid Locomotives, and can provide the products with different power range from 200kW to 3000kW to fully meet the demands of various customers.
