Electric locomotive

technology Maturity 11-13 Next article →

An electric locomotive is a special machine used to pull trains. It gets its power from electricity instead of burning fuel. This electricity can come from overhead lines or a third rail on the ground. Some locomotives even carry their own power in batteries or supercapacitors. These machines are very efficient because electric motors work so well. Many of these motors have an efficiency of over 90%.

There are many ways these locomotives work. One smart way is called regenerative braking. This is a process where the train recovers energy while it is slowing down. The movement of the train turns back into electricity. This power is then sent back onto the power lines. Newer models use AC motor-inverter drive systems to do this. This helps save energy every time the train stops.

People have been building these machines for a long time. The first known electric locomotive was built in 1837 by Robert Davidson. He lived in Aberdeen and used batteries to power it. Later, in 1879, Werner von Siemens showed an experimental train in Berlin. This train used a third rail to get its power. By 1883, the first tram using overhead lines opened in Austria.

Many different places have used these trains for different reasons. In the United States, the Baltimore Belt Line used electric locomotives in 1895. They did this to move trains through tunnels without smoke. In Italy, the Valtellina line opened in 1901 as the first long mainline. This line used a three-phase AC system. In Hungary, engineers like Kálmán Kandó helped develop new motor designs. He even invented a rotary phase converter in 1918.

Electric locomotives are great for many different jobs today. They are very quiet because they have no big engines. This makes them perfect for commuter trains that stop often. They are also good for heavy freight on busy paths. They can even produce more power than diesel engines for fast starts. While building the wires is expensive, these trains cost much less to run. They are much cleaner for the air we breathe.
