locomotive
Let an agent explain locomotives and their types and workings, describe their history and classification, identify notable classes and preserved examples with sources, and support railway, engineering and heritage questions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain locomotives and their types and workings, describe their history and classification, identify notable classes and preserved examples with sources, and support railway, engineering and heritage questions.
A rail vehicle that provides the motive power for a train, pulling or pushing unpowered carriages and wagons, developed from steam locomotives in the early nineteenth century through diesel, diesel-electric and electric locomotives to modern high-power designs, and classified by power source, wheel arrangement, duty such as freight, passenger or shunting, and gauge; locomotives are central to railway operation and history and many are preserved in museums and heritage railways.
What it is for: Rail vehicles providing train motive power.
It can be explain types and workings; describe history; identify notable classes; support railway questions.
Distinguishing features
Motive power
Separate from carriages
Power source classification
Heritage interest
What it looks like
Powered rail vehicles at the head or rear of trains.
How it is recognised
Powered rail vehicle hauling a train
Steam, diesel, electric
Multiple units carry their own power in passenger cars; railcars are self-propelled single vehicles
