tunnel
Let an agent explain tunnels, relay construction methods, types, safety and notable examples from civil engineering sources, describe the named forms and flag figurative aliases, route tunnel emergencies, and distinguish tunnels from bridges, cuttings, culverts and caves.
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 tunnels, relay construction methods, types, safety and notable examples from civil engineering sources, describe the named forms and flag figurative aliases, route tunnel emergencies, and distinguish tunnels from bridges, cuttings, culverts and caves.
An underground passage bored through soil or rock, or under water, for roads, railways, canals, pedestrians, utilities or mining, distinct from a bridge or cutting, with forms and examples the registry aliases name such as Roman tunnels, international tunnels crossing borders, ski tunnels and, more loosely, the natural drive-through tree and the biological tunnel of aggression, which are figurative and appear misfiled; tunnels are built by drilling and blasting, tunnel boring machines or cut-and-cover, and require ventilation, drainage and fire safety, so users should follow signs and emergency procedures, and tunnel fires and floods are serious hazards.
What it is for: Underground passage for transport, utilities or mining.
It can be explain construction methods and types; relay safety; describe named forms and flag figurative aliases; route tunnel emergencies.
Distinguishing features
Enclosed passage
Through ground or water
Needs ventilation and safety
Several construction methods
What it looks like
An enclosed passage through ground or under water, with portals, lighting and ventilation.
Physical character
methods: drill and blast, tunnel boring machine, cut-and-cover list
longest rail tunnel: Gotthard Base Tunnel note - as reported
registry parents: underground structure, thoroughfare note
How it is recognised
Underground or underwater passage
Drive-through tree, tunnel of aggression, Roman tunnel, tik-kuyu, international tunnel, ski tunnel
Bridges span over obstacles; cuttings are open trenches; culverts carry water under roads; caves are natural
