Locomotives in this atlas's Rail Vehicles category, rail vehicles that haul or push trains and supply their power, whether by steam, diesel fuel or electricity. Belongs here: a steam, diesel, electric or gas-turbine locomotive. Does not belong here: an unpowered railcar, gathered under Passenger Railcars or Freight Railcars. It sits within Intercity and Heavy Rail, in the Rail Vehicles category, and holds the individual vehicles of this kind, with their make, model, generation and model year pages where the atlas has minted them.
