What it is Filled
The rails, fastenings and supporting structure on which trams run, laid in or beside streets with grooved rails embedded in paving, on reserved track with ballast or slab, or on prefabricated panels such as the Budapest BKV panels, with points, crossings and curves designed for street geometry; tramway track must accommodate road traffic where it shares the roadway, drain, limit noise and vibration and integrate with overhead power, and is built and maintained under light rail standards.
Why it exists Filled
Let an agent explain tramway track and its forms, relay design, construction and maintenance practice from standards and references, describe integration with streets and power, and distinguish tramway track from railway and metro track.
Distinguishing features Filled
- Grooved rail
- Street integration
- Tight curves
- Noise and vibration control
What robots and AI may and may not do Filled
Must not
- Leave objects on or near tram tracks or interfere with points and signals.
- Report a track as safe when inspection found defects.
- Direct cyclists or wheelchair users to cross rails at angles that trap wheels.
- Carry out track works without the operator's possession of the line.
Only with a human decision
- Reopening a section of track after repair or derailment.
May
- Monitor and report track wear, defects and obstructions on networks it is authorized to inspect.
- Warn cyclists and road users about grooved rails where the operator publishes such advice.
Moral aspects Filled
- Rails in streets injure cyclists and pedestrians who catch wheels or slip.
- Track failures can derail trams carrying many people.
Who is affected
- Tram passengers
- Cyclists and pedestrians
- Track workers
Owners Filled
Steward
The tram network's infrastructure operator.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.tramway-track
- Wikidata: Q728943 (https://www.wikidata.org/wiki/Q728943)
Direct properties required Filled
- standard gauge: 1435 mm - most systems; metre gauge common in Europe
- grooved rail profile: Ri60 and similar type
Recognition required Filled
- Rails for trams in or beside streets
- Embedded, slab, ballasted, grass and panel track
- Railway track uses flat-bottom rails on sleepers; metro track is segregated
- Grooved rails flush with paving in streets, or ballasted or grassed track on reserved alignments.
Capabilities and actions required Filled
- explain forms and components
- relay design and construction practice
- relay maintenance and noise control
- distinguish from railway track
Hazards and failure modes required Filled
- Rail corrugation and wear
- Cyclist falls on grooved rails
- Stray current corrosion
- Track buckling in heat
Standards and interfaces required Filled
- EN 14811 grooved rail standard
- National light rail and tramway regulations
- Road traffic rules for shared track
- Noise and vibration limits
Context of use required Filled
- Carrying trams through streets and reserved corridors.
- embedded street track
- slab and prefabricated panel track such as BKV panels
- ballasted reserved track
- grass track
- special trackwork: points, crossings, grand unions
- depot and stabling track

Open questions
- Should grooved rail be a separate entry?
- How should standards be linked?
- The registry entry has a merged alias naming a proprietary panel system; should it be split off?
