What it is Filled

A route of track and associated infrastructure over which trains run between points, including mainlines, metro lines, funiculars, test tracks and express corridors, often identified by line names or numbers.

Why it exists Filled

Let an agent handle railway and metro lines by name, operator, route, stations, service and status.

Distinguishing features Filled

  • Defined rail route
  • Owned by infrastructure manager
  • Served by operators
  • Electrified or not

What robots and AI may and may not do Filled

Must not

  • Enter or tell people to enter tracks or restricted areas.
  • Interfere with signalling, power or control systems of a line.
  • Publish security-sensitive details of infrastructure beyond what operators make public.
  • Report a line as open or safe when the operator has closed it.

Only with a human decision

  • Operating trains or controlling traffic on a line.
  • Permitting work on or near live tracks.

May

  • Report routes, stations and timetables from the operator's official data.
  • Report disruption and planned closures to passengers.

Moral aspects Filled

  • Railways move many people safely only when every rule is kept; one breach can kill.
  • Line closures and fares affect access to work and services.

Who is affected

  • Passengers
  • Railway workers
  • People living near the line

Owners Filled

Steward

The infrastructure manager; the operator runs the services and the rail regulator oversees safety.

Master systems

  • National rail infrastructure registers
