railway track
Let an agent handle railway track by gauge, construction, layout, maintenance and safety, including trespass and level crossing risks.
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 handle railway track by gauge, construction, layout, maintenance and safety, including trespass and level crossing risks.
The structure on which trains run, consisting of rails fastened to sleepers (ties) laid on ballast or a slab, with switches, crossings and fixed gauge; arranged as single, double or multiple track lines.
What it is for: Guiding and supporting trains.
It can be identify track gauge and components; explain switches and crossings; find maintenance and possession information; understand track safety rules.
Distinguishing features
Fixed gauge
Continuous welded or jointed rail
Requires regular maintenance
Dangerous to trespass
What it looks like
Two steel rails on sleepers and ballast, with points and signals.
Physical character
standard gauge: 1435 mm
How it is recognised
Rails, sleepers, ballast or slab
Points (switches) and crossings
Tram tracks are embedded in streets
