high-speed railway line
Let an agent identify a high-speed line and its standard, relay speeds, length, operators and safety systems from official sources, and separate high-speed lines from conventional main lines and from the trains that use them.

What it is Filled
A railway line built or upgraded for trains running at high speed, in international practice at least 250 km/h on new lines or 200 km/h on upgraded lines, with dedicated track geometry, signalling, power supply and grade separation; examples include the Japanese Shinkansen, French LGV, Chinese, Spanish and German networks.
Why it exists Filled
Let an agent identify a high-speed line and its standard, relay speeds, length, operators and safety systems from official sources, and separate high-speed lines from conventional main lines and from the trains that use them.
Distinguishing features Filled
- Built for sustained speeds above 200 or 250 km/h
- Grade separated, no level crossings
- Cab signalling and train control
- Dedicated or mixed traffic by design
What robots and AI may and may not do Filled
Must not
- Direct anyone onto high-speed track or into restricted areas.
- Interfere with signalling or train control systems.
- Present projected routes as decided when they are not.
- Understate noise and land-take impacts on communities.
Only with a human decision
- Route planning and land acquisition decisions.
- Operational changes to signalling or speeds.
May
- Report route, speeds and services from operators and infrastructure managers.
- Explain technical standards for high-speed lines in general terms.
Moral aspects Filled
- Trains at high speed leave no margin for people on the line.
- New lines displace homes and divide communities and habitats.
Who is affected
- Passengers
- Communities along the route
- Track workers
Owners Filled
Steward
The infrastructure manager; national railway authorities license lines and operators.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.high-speed-railway-line
- Wikidata: Q858485 (https://www.wikidata.org/wiki/Q858485)
- line name or code: operator naming such as LGV Sud-Est
- UIC and national line numbers: numeric infrastructure registers
Direct properties required Filled
- design speed: 200-350 km/h - by line
- minimum curve radius: about 4000-7000 m - for 300 km/h and above
- length: tens to thousands km - by line and network
Recognition required Filled
- No level crossings, wide curves, overhead power
- Dedicated high-speed signalling such as ETCS or ATC
- Upgraded conventional lines and the trains themselves are separate matters
- A straight, gently curved, fenced double track without level crossings, with overhead electrification and long viaducts and tunnels.
Capabilities and actions required Filled
- identify the line, its standard and operator
- relay design speed, length and opening dates
- explain infrastructure requirements
- route service and ticket questions to operators
Hazards and failure modes required Filled
- Derailment at speed
- Earthquake and weather disruption
- Cost overruns and delays in construction
- Noise and land-take impacts
Standards and interfaces required Filled
- UIC definitions of high-speed rail
- EU technical specifications for interoperability
- National railway safety regulations
- Environmental assessment law for construction
Context of use required Filled
- Carrying passenger trains at high speed between cities.
- new dedicated lines such as LGV and Shinkansen
- upgraded conventional lines
- mixed passenger and freight high-speed lines
- maglev lines as a separate technology
- national networks by country

Open questions
- Should each line be a separate entry?
- How should infrastructure registers be linked?
- The registry entry has merged aliases for a maglev test line; should it be split off?
