What it is Filled

A steam locomotive that carries its own fuel and water in tanks and bunkers mounted on the locomotive frame rather than in a separate tender, in forms such as side tanks, saddle tanks, pannier tanks and well tanks, and articulated types such as the Fairlie, built for shunting, suburban, branch line and industrial service worldwide, with examples from the Austrian kkStB 4.0, the New Zealand B and E classes, the Cape Government Railways Fairlie 0-6-6-0 to the Greek OSE class Z; tank locomotives were widespread on narrow gauge and preserved railways.

Why it exists Filled

Let an agent explain tank locomotives and their types, relay design, uses and notable classes from railway history sources, describe preservation, and distinguish tank locomotives from tender locomotives.

Distinguishing features Filled

  • Onboard water and fuel
  • Bidirectional running
  • Short-range service
  • Many tank layouts

What robots and AI may and may not do Filled

Must not

  • Operate a steam locomotive without the qualified crew and boiler certification its railway requires.
  • Report a boiler as fit for steaming without a valid inspection.
  • Move a locomotive on a running line without authority from the railway operator.
  • Remove parts or fittings from a preserved locomotive without the owner's consent.

Only with a human decision

  • Approving a steam locomotive for passenger service after overhaul.

May

  • Explain tank locomotive layouts such as side, saddle, pannier and well tanks, citing railway history sources.
  • Identify a preserved tank locomotive from its class and builder records.
  • Report the condition of a locomotive to the preservation group that keeps it.

Moral aspects Filled

  • Steam boilers store dangerous energy; failures have killed crews and bystanders.
  • Preserved locomotives are shared heritage kept by volunteers and trusts.

Who is affected

  • Crews and volunteers
  • Passengers and spectators
  • Heritage railway owners

Owners Filled

Steward

The owner of the locomotive, often a heritage railway or trust; the railway safety authority licenses its operation.

Master systems

  • Heritage railway and rolling stock registers

  • tender locomotive - which tows a tender
  • shunting - and suburban service
  • heritage railway - lines worldwide

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.tank-locomotive
  • Wikidata: Q785745 (https://www.wikidata.org/wiki/Q785745)

Direct properties required Filled

  • typical water capacity: about 2000-10000 litres
  • wheel arrangements: from 0-4-0T to 2-8-4T and articulated range

Recognition required Filled

  • Steam locomotive with onboard tanks
  • Side, saddle, pannier and well tanks; Fairlie and other articulated tank types; classes such as kkStB 4.0, NZR B and E, OSE class Z
  • Tender locomotives tow a separate tender; diesel and electric locomotives are not steam
  • A steam locomotive with water tanks beside or over the boiler and a coal bunker behind the cab.

Capabilities and actions required Filled

  • explain types and design
  • relay uses and classes
  • describe preservation
  • distinguish from tender locomotives

Hazards and failure modes required Filled

  • Limited range from small tanks
  • Boiler safety in preservation
  • Confusing tank layouts and classes

Standards and interfaces required Filled

  • Historical railway engineering standards
  • Boiler inspection rules for preserved locomotives
  • Heritage railway safety regulation

Context of use required Filled

  • Hauling trains without a tender.
  • side tank locomotives
  • saddle tank locomotives
  • pannier tank locomotives
  • well tank locomotives
  • articulated tank types such as Fairlie, Garratt and Mallet tanks
  • industrial and narrow gauge tank locomotives
  • notable classes such as kkStB 4.0, NZR B class, NZR E class, CGR Fairlie 0-6-6-0, CCFPP 1 and 2, OSE class Z

Sources Filled

  1. Wikidata item Q785745: tank locomotive - identity and sense of the item
  2. Wikipedia: Tank locomotive - general description of the item

Open questions

  • Should saddle tank and Fairlie locomotive be separate primary entries?
  • How should railway history sources be linked?
  • The registry entry has merged aliases naming specific classes; should they be split off?
