It is the social responsibility of every rail transit equipment enterprise to protect the environment in which human beings live and to create green products. As the pioneer of China’s domestic electric hybrid green locomotive manufacture, CRRC Ziyang Co regards environmental protection as its responsibility and actively responds to the call of building in a way that is ‘resource-saving and environment-friendly’.

Since 2005, CRRC Ziyang Co has been researching and demonstrating the power of locomotive hybrid technology and has committed to providing green, healthy, and comfortable rail transit products for global customers. The company independently developed new environmental protection products including hybrid locomotives, new energy air rail, and all-electric railcars.

Hybrid locomotives: fuel saving, emission reduction, and noise reduction

It’s power source consists of a power battery pack and diesel generator set, out of which the power battery pack is preferred. At the same time, this type of locomotive also has many advantages, such as saving locomotive brake shoes, fast starting acceleration, strong dynamic braking capacity during operation, low noise and pollution. Fuel saving, emission reduction, and noise reduction all have a very good effect. The users of China’s steel enterprises highly praised this locomotive. While achieving remarkable results in energy saving, the 1000 kW diesel-battery hybrid locomotive won the ‘Energy Saving and Emission Reduction Technology Innovation Award’ of China.

At present, CRRC Ziyang Co has established a hybrid locomotive technology and product platform, which can provide hybrid locomotives of different power level from 200kW to 3000kW, saving fuel consumption by 30% to 50%, reducing harmful emission by 40% to 80%, and reducing the impact time of diesel engine noise by more than 80%, to fully meet the needs of different users.

Hanging monorail train: environmental protection, low noise, small footprint

On 8 December 2016, CRRC Ziyang Co completed the construction of China’s first new energy commercial air train. By integrating five mature locomotive technologies, four innovative patented technologies, and 16 patented technologies, the company developed a new type of hanging monorail train driven by a permanent magnet motor and powered by a battery with high reliability, high economy, high adaptability, and high safety.

The air train has many advantages, such as green environment protection, low noise, high safety performance, less land occupation, and good environmental coordination. It is in line with the national requirements of energy saving, emission reduction, and green development, and can effectively alleviate urban traffic problems. Its cost is relatively low, approximately 1/5 to 1/8 of subway costs, and 1/2 to 1/3 of straddle-type monorail costs. So far, the company has customized various types of new energy monorail train for many customers, and has been widely recognised by them.

Purely battery-powered railcar: zero-emission, low-noise, high-economy

On 22 August 2019, CRRC Ziyang Co launched the purely battery-powered railcar, which is another new green rail transit product after the ‘dual-fuel’ locomotive. This new energy railcar has the advantages of low noise, zero emission, high economy, humanised design, active and passive safety protection, and portable charging.

It can effectively replace the traditional diesel railcars and is widely used in railroad track laying and maintenance, industrial and mining enterprises’ public works, and electrical operations. The use of the system can reduce the emissions by 630kg of exhaust gas per year while also effectively reducing energy consumption and maintenance costs, greatly improving the working environment of operators. During the operation of this railcar, the noise of the driver’s cab is less than 70 decibels, which is much lower than that of traditional diesel locomotives, and it can operate quietly in urban areas and at night, without affecting the surrounding living environment, making it an environmentally friendly, economic, efficient, clean, and safe rail transportation product.

Since its establishment in 1966, CRRC Ziyang Co has always set its eyes on the world and insisted on the road of internationalisation while also being a pioneer in China for manufacturing internal combustion engine products for the world. In 1992, the company’s diesel locomotive was exported to Thailand and became the first commercial locomotive exported from China. Now, the company has exported more than 1000 diesel locomotives, which comprises 50% of China’s total exports of diesel locomotives. In terms of energy saving, emission reduction, and the intelligent manufacturing of rail transit, the company grows together with customers from more than 40 countries and regions in Asia, Africa, America, Oceania, and Europe.

On the day to reaffirm concern for the preservation and enhancement of the environment, CRRC Ziyang Co is willing to work with all partners to promote the coordinated development of the rail transit industry and nature, and jointly care for our beautiful homeland!
