New advancements, including diesel-electrical hybrid and battery power, have ushered in a new dawn of locomotive innovation. While the rail industry is already credited with being minimally damaging to the environment when compared to other popular modes of transport, these developments bring about even greater reductions to CO₂ emissions – among a myriad of other benefits.
Below, we’ll outline some of the main advantages of battery-powered locomotives for long distance haulage and discuss the potential future of the technology.
Benefits Of Electric Shunting Locomotives
1. Improved Efficiency & Flexibility
A significant innovation in locomotive design has been driven by new advancements in battery technology. For example, the integration of battery systems has led to hybrid locomotives with diesel and electric power, improving efficiency and flexibility.
In 2019, Clayton Equipment developed the Hybrid+™ CBD90 Shunting Locomotive – one such hybrid technology that significantly reduces costs and emissions. It allows for a significant reduction in fuel consumptions, thereby driving down both carbon emissions and costs.
2. Lower Emissions
A battery-powered locomotive produces zero emissions during operation, contributing to cleaner air and a reduction in greenhouse gases.
Clayton Equipment is a worldwide supplier of zero-emissions locomotive haulage equipment. As our locomotives are battery-powered, they don’t use fuel or emit greenhouse gases, meaning they offer 100% emission-free operation. One example is the Clayton Equipment CB45 Locomotive, part of a new generation of shunting locomotives. A battery only design, it is low emission, low noise and offers lower operating and maintenance costs despite its ample haulage capacity and impressive performance.
3. Reduced Energy Consumption
Modern batteries have improved locomotive energy efficiency. For example, regenerative braking systems capture and store braking energy, reducing overall energy consumption. Additionally, this technology results in less brake wear and reduced charging times, meaning it requires far less maintenance – ultimately driving down costs.
4. Improved Performance
A battery-powered locomotive can provide high torque at low speeds, improving performance in challenging conditions such as steep gradients or heavy loads. There is also often a tandem working option – whereby two locomotives are operated by one driver from a single cabin. Another huge advantage is that there is the option of on-board hybrid or depot-based battery charging, providing much greater flexibility.
The Future Of Long-Distance Haulage
The rail industry is experiencing rapid technological advancements, not least in the area of battery and electric operation. Transitioning to hybrid diesel-electric models and fully battery-operated locomotives will significantly drive down CO₂ emissions and lead to an overall more sustainable, more efficient and lower cost rail industry.
