Locomotive

A powered railway vehicle that moves trains by supplying the force needed to pull or push other rail vehicles. Locomotives may carry their own energy source or draw power from external infrastructure.

Steam locomotive: A locomotive that uses a steam engine to drive its wheels. Its boiler and cylinders convert heat into the motion that hauls a train.
Railway track: A guided path of rails and supporting structures on which railway vehicles travel. Its gauge, curves, and load limits shape where a locomotive can operate.
Richard Trevithick: A British engineer whose high-pressure steam engines included an early steam locomotive demonstrated in 1804. His locomotive showed that a steam engine could haul vehicles on rails.
Freight train: A train that carries goods rather than passengers. Freight locomotives are configured to haul heavy loads, often at lower speeds.
Railcar: A powered railway vehicle designed to carry passengers or goods, often operating singly or in small formations. Unlike a locomotive, a railcar carries its own payload as well as propulsion equipment.
Diesel locomotive: A locomotive powered by a diesel engine, usually through electric or mechanical transmission. It replaces steam generation with an onboard diesel power plant.
Railway coupling: A mechanical device that joins railway vehicles so they can transmit pulling and pushing forces. Couplings connect a locomotive to the vehicles it hauls.
George Stephenson: A British civil and mechanical engineer associated with early public railways and steam locomotives. His locomotives and railway work helped establish steam haulage as a practical system.
Passenger train: A train designed to carry people between stations. Passenger service favors acceleration, speed, and reliable timetable performance.
Tender (railway vehicle): A vehicle coupled behind a steam locomotive to carry fuel and water. A tender supports the locomotive's operation but does not supply its tractive power.
