What is Electric locomotive?
[[File:Classic preserved West Coast Main Line 1960s electric locomotive 'Les Ross.' - panoramio.jpg|thumb|An electric locomotive]] An '''electric locomotive''' runs on [[electricity]] as the name suggests. Electric locomotives cost the least to buy and operate. However, the [[railway electrification system]] is very expensive, so only tracks used by many trains per day are usually electrified. Thus, electrics are only the second next used type, behind [[diesel locomotive]]s. Electric locomotives get their power from three main sources: overhead lines, an on-board battery, or a third rail. There are many different types of electric locomotives. Battery-electric locomotives are powered by on-board batteries. They are used in situations where other types of engines could be dangerous. {{Transport-stub}} [[Category:Locomotives]]
