electric trains

Electric trains are very special trains that run on electricity instead of fuel. Instead of burning fuel to power the train, it uses electricity that is sent to the train through wires that run along the tracks. This electricity makes the engine move and is what helps the train go forward. The wires also provide power for lights, HVAC, and other important functions. Electric trains are better for the environment because they don't produce any harmful pollutants like fumes, smoke, or carbon dioxide.
