: Critical for safety; includes automatic brakes for the train cars and independent brakes for the locomotive itself.

: The primary power source (boiler for steam, diesel engine for others).

: Use a boiler to create high-pressure steam that drives pistons and rods to turn the wheels.

A locomotive is a rail vehicle that provides the motive power for a train. While "train" typically refers to the entire series of connected carriages, the is specifically the engine that pulls or pushes them. Types of Locomotives Locomotives are generally classified by their power source:

: Draw power from external sources like overhead lines or a third rail. Core Components

: The control center where the engineer operates the throttle, brakes, and direction of travel. Guide :: Locomotive Factorio Guidebook - Steam Community

: Use a diesel engine to generate power, often transmitted to wheels via electrical traction motors (Diesel-Electric) or gearboxes.

: Convert the engine's power into physical movement on the rails.
