What it is Filled

A rail vehicle that runs on tracks along urban streets or reserved lanes, powered mostly by electricity from overhead wires or batteries, carrying passengers in single or articulated units, also called streetcar or trolley, with variants from historic trams to modern low-floor light rail vehicles, restaurant trams and cable-hauled cars; trams are operated by transit agencies under rail and road rules.

Why it exists Filled

Let an agent explain trams and their kinds, support using tram networks, describe tram technology and history, and relate trams to urban transport planning.

Distinguishing features Filled

  • Street running
  • Electric traction
  • Passenger service
  • Articulated forms

What robots and AI may and may not do Filled

Must not

  • Operate a tram without authorization or with failed brakes or doors.
  • Encourage people to walk, cycle or park on tram tracks or near overhead wires.
  • Interfere with tram signals, points or power supply.
  • Hide a collision or near miss from the operator.

Only with a human decision

  • Restarting service after a collision or derailment.
  • Diverting or suspending a tram line.

May

  • Report tram routes, times and service changes from the operator.
  • Drive or dispatch a tram only where it is authorized by the operator and safety system.

Moral aspects Filled

  • Trams share streets with pedestrians and cyclists, so collisions can be deadly.
  • Trams give access to cities for people who cannot drive.

Who is affected

  • Passengers
  • Pedestrians and cyclists
  • Tram drivers

Owners Filled

Steward

The tram operator; the transport authority owns the network in many cities.

Master systems

  • Railway and tramway vehicle registers

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.tram
  • Wikidata: Q3407658 (https://www.wikidata.org/wiki/Q3407658)

Direct properties required Filled

  • Overall vehicle length: m - Measure between the outermost ends of the vehicle and specify whether couplers are included.
  • Vehicle mass: kg - Obtain mass from weighing or vehicle specifications and distinguish empty condition from passenger loading.
  • Track gauge compatibility: mm - Record the specified distance between the inner rail faces for the track on which the vehicle is designed to run.
  • Boarding floor height: mm - Measure the entrance floor height above the top of the rail under a stated loading condition.

Recognition required Filled

  • Runs on street rails
  • Electric, often overhead wires
  • A bus has no rails; a metro runs on segregated track
  • A long rail vehicle on street tracks, often with a pantograph.

Capabilities and actions required Filled

  • explain kinds of tram
  • support using tram networks
  • describe technology and history
  • relate to transport planning

Hazards and failure modes required Filled

  • Collisions with road users
  • Derailments
  • Overhead line hazards

Standards and interfaces required Filled

  • Tramway safety regulations
  • Vehicle accessibility standards
  • Road traffic rules for trams

Context of use required Filled

  • Street-running passenger rail vehicles.
  • historic and heritage trams
  • modern low-floor trams
  • articulated and multi-section trams
  • tram-trains and light rail vehicles
  • special trams such as restaurant and cable trams

Sources Filled

  1. Wikidata item Q3407658: tram - identity and sense of the item
  2. Wikipedia: Tram - general description of the item

Open questions

  • Should each tram model be a separate entry?
  • How should network data be linked?
  • How should safety statistics be linked?
