The HOSteam mailing list discusses issues relating to modeling of steam locomotives in HO scale or closely related sclaes such as narrow gauge and Sn3 and Sn3.5. The group is intended to be narrow in focus (i.e. not intended for N scale or larger scales like O scale), due to differing modeling techniques in these other scales.

Here is a list of currently available HO steam locomotives by wheel arrangement. The manufacturer is listed along with the prototype of the engine. Some locomotives don't have prototypes or the prototype is not known.
