What it is Filled
A steam locomotive that hauls a separate vehicle, the tender, carrying its fuel and water, as opposed to a tank locomotive that carries them on its own frame; many historical classes worldwide.
Why it exists Filled
Let an agent handle tender locomotives by class, railway, wheel arrangement, preservation and history.
Distinguishing features Filled
- Separate fuel and water tender
- Longer range than tank engines
- Many national classes
- Largely heritage today
What robots and AI may and may not do Filled
Must not
- Operate, fire or move a steam locomotive without being authorized and qualified.
- Tamper with a locomotive's boiler, brakes or safety valves.
- Allow people near a live steam locomotive without the operator's supervision.
- Remove parts or fittings from a preserved locomotive.
Only with a human decision
- Steaming, moving or coupling a locomotive.
- Disposing of or altering a historic locomotive.
May
- Describe tender locomotive classes and history from railway archives.
- Report the condition of a preserved locomotive to its operator.
Moral aspects Filled
- A steam boiler stores great energy and can kill if mishandled.
- Preserved locomotives are heritage held for the public.
Who is affected
- Crew and volunteers
- Visitors and passengers
- Railway heritage
Owners Filled
Steward
The railway or heritage operator that keeps it; railway safety regulators oversee its operation.
Master systems
- National railway rolling stock and heritage vehicle registers

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.tender-locomotive
- Wikidata: Q20650761 (https://www.wikidata.org/wiki/Q20650761)
- class and running number: railway-specific locomotives
- Whyte notation: wheel arrangement classification
Direct properties required Filled
- Operating mass: t - Mass is measured or taken from technical records with tender inclusion and fuel and water loading explicitly stated.
- Overall length: m - Length is measured between specified end reference points with the locomotive and tender coupled.
- Track gauge: mm - Compatible track gauge is specified as the distance between the inner rail faces at the prescribed measurement level.
- Boiler working pressure: MPa - Working pressure is obtained from boiler documentation with gauge or absolute pressure explicitly identified.
- Tender water capacity: m3 - Water capacity is obtained from tender specifications or measured volume with usable and total capacity distinguished.
Recognition required Filled
- Separate tender behind the cab
- Whyte notation such as 4-6-2
- Tank locomotives carry fuel on board
- A steam engine coupled to a separate tender carrying coal or oil and water.
Capabilities and actions required Filled
- identify classes and wheel arrangements
- find preserved examples
- research railway history
- ride heritage trains
Hazards and failure modes required Filled
- Boiler failures
- Lineside fires from sparks
- Burns and scalds in operation
Standards and interfaces required Filled
- Heritage railway safety rules
- Boiler inspection regulations
Context of use required Filled
- Long-distance steam haulage; today heritage operation.
- express passenger tender locomotives
- freight tender locomotives
- articulated tender locomotives
- preserved heritage locomotives
Sources Filled
- Wikidata item Q20650761: tender locomotive - identity and sense of the item
- Wikipedia (sv): Tenderlok - general description of the item
Open questions
- Should classes be separate entries?
- How should preserved examples be linked?
- How should wheel notations be recorded?
