HOn30 gauge

Definitions

The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while H0e is used for European prototypes. In Britain, the term OO9 is used.{{cite web

HOn30

(narrow gauge) HOn30 is often used to model the gauge railroads in the US state of Maine. The first HOn30 / HOn2½ ready-to-run (RTR) brand introduced in the US was the AHM MinitrainS, initially manufactured by Egger-Bahn and later by Roco and Mehanoteknika Izola, also known as Mehano.

Perhaps the most fascinating part of HOn30 is that RTR models are still scarce. One exception is The MinitrainS line that was upgraded in 2011.

H0e

(Narrow gauge) H0e is a gauge defined by the (NEM). According to that standard, H0e represents narrow gauges between 650 and(-), though it is often used to represent gauge railways as well. In strict scale H0e represents a theoretical gauge of 783 mm, which does not exist as a prototype. But this is very close to the gauge of the gauge railways most widely used in Germany, gauge railways Bosnian gauge most widely used in the former Austro-Hungarian empire, gauge rack railways in Switzerland as well as to the gauge used in parts of the British Empire.

Development

H0e scale was invented by Egger-bahn in 1963 - for a long time out of production, but some of the Egger-Bahn line has been reintroduced by MinitrainS. Other manufacturers to produce HOe in recent years have included Roco, Liliput, Bemo and Tillig.

United States

In 1965 Bob Hayden and Dave Frary stumbled upon an Associated Hobby Manufacturer's AHM "MinitrainS" HOn (now named HOn30) train set at a Woolworth's department store and decided to use it to model Maine 2-foot railroads in HO scale.

The AHM MinitrainS line was introduced only a few years after N scale appeared in Europe. The product line represented North American prototypes in HO scale, using N-gauge track. AHM offered two industrial locomotives, a Plymouth diesel and a Baldwin steam locomotive.

Hayden & Frary used the AHM trains to model a HOn 3 x portable model railroad called the Elk River Line. The layout appeared in articles starting in the April 1970 issue of Railroad Model Craftsman.

The pair built a second HOn layout called Thatcher's Inlet, a 6-foot-by-30-inch (72 x) shelf-type switching layout. It was inspired by the Wiscasset waterfront of the Maine 2-foot railroads. The equipment was based more on available N-gauge products than on the AHM MinitrainS line it reflected the growing variety of N-gauge equipment and accessories available in the early 1970s.

Next came Dave Frary's 12 x HOn Carrabasset & Dead River Ry (C&DR), one of the first known large model railroad to utilize HOn. It appeared in the November 1979 and February 1980 issues of Model Railroader.

In 1974, Bob Hayden started his own version of the C&DR. Its first engine was a reworked AHM MinitrainS steamer. The first C&DR road diesels, No. 25 and 26, were based on Minitrix N-gauge Fairbanks-Morse switchers. Hayden's C&DR was featured in Model Railroader's Great Model Railroads 1991 annual.

During the mid-1970s a Japanese company, Sango, made a kit for a 2-6-0 Baldwin engine which showed a great improvement in running ability. This started a growing interest in HOn in Japan. From 1978 to 1982, Joe Works, Sango, and Flying Zoo kits and built-up brass models came on the scene. There was a thriving interest in Japan in 2-footers using N-gauge track, as this allowed more HO scale modeling in less space than traditional HO gauge track.

Related scales

The other NEM defined narrow gauges for H0 scale are H0m gauge (using gauge originally TT scale track) for models of gauge and similar prototypes and H0i or H0f gauge (using Z-scale track) for prototypes around – the most popular gauge for industrial (or Feldbahn) railways.

In the United Kingdom where the most popular railway modelling scale is 1:76 designated 4 mm scale. The narrow-gauge equivalents to H0e and H0m are OO9 and OO12. For modelling gauge railways – widely used in Ireland and the Isle of Man – a gauge track (as for H0m) is used. For modelling the same track in HOn3 or OOn3 – widely used in the United States – the track is .

In the United States the NMRA have developed many standards for narrow-gauge modelling, including those modelling in HOn30 and its related gauges.

Summary

Table

The following table lists the most popular narrow gauges in HO and OO scale:

Remarks

Model railroaders with layouts and rolling stocks by American standard and usually by British standard use for designation of the scale in English language publications the letter O and not the number 0.

In Great Britain and rarely in the French language for narrow gauge it is written after designation of the scale the model gauge in millimetres, for example, OO9 or OO6.5 in United Kingdom and H09 rather than H0e or H06,5 rather than H0f in France.

In Great Britain and in the French language it is written sometimes with a hyphen or en dash between the scale and the model gauge, for example, OO–9 or H0-9.
