Category:Well Tank Engines

are small tenderless s that have water stored in a well on the underside of the locomotive, generally between the locomotive's frames.

This does not restrict access to the boiler, but space is limited there, and the design is therefore not suitable for locomotives that travel long distances before refilling.

The arrangement does, however, have the advantage of creating a low centre of gravity, creating greater stability on poorly laid or narrow gauge tracks.

Note that this category is not reserved for canon content. Fictional locomotives, including anthropomorphic ones are most certainly welcome to be added to this category.
