This week we are looking at HOn 2 1/2 HOn30 and HOe. The truth is these are all basically the same thing. Ho. trains that run on "N Gauge" track, 9mm. Also used in "O" scale as On18.
HOn2 1/2 is the same as saying HOn30 Two and a half feet, or thirty inches. HOe is an expression for any European (e) narrow gauge modeled in HO scale and using 9mm track.
HOn30 was quite popular in the United States in the 1980s, but its popularity has fallen off. Several great products were imported into the US from Japan by Joe Works.
HOe and OOe are still very popular in Europe, especially in Germany, Switzerland, and Austria.
