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 electric locomotive technology and types, describe specific classes with sources, compare with other traction, and describe electrification systems.

A locomotive powered by electricity drawn from overhead lines, a third rail or on-board batteries, or in hybrid forms combining electric and diesel or steam power, used for passenger and freight haulage on electrified railways; electric locomotives are efficient, powerful and quiet and come in many classes across national railways.

What it is for: Electric rail traction.

It can be explain technology and types; describe specific classes; compare with diesel and steam traction; describe electrification systems.

Distinguishing features

External or battery power

High power-to-weight

Quiet and efficient

Requires electrification

What it looks like

A locomotive with pantograph or shoe gear and no visible fuel tanks or chimneys.

How it is recognised

Pantograph or third-rail pickup

Electric traction motors

Diesel locomotives carry their own engine and fuel
