A Battery Electric Locomotive is a type of train that runs on electricity stored in batteries, rather than relying on traditional diesel engines or overhead power lines. This technology allows for cleaner and quieter operations, making it an environmentally friendly option for rail transport. These locomotives are particularly useful in areas where electrification of tracks is not feasible. They can be charged at stations or during stops, enabling them to travel short to medium distances without emitting harmful pollutants. As the demand for sustainable transport grows, battery electric locomotives are becoming an important part of modern rail systems.
