The large scale backyard railroad hobby consists of individuals who love railroads and who want to operate trains in as real a manor as possible. Most can’t afford to own and operate full size trains and are not satisfied operating table top trains. There are many choices about scale and track gauge to be made by the prospective large scale backyard railroad tycoon. Miniature railroads have been built in every conceivable scale from 1/2" to the foot to 6" to the foot. and track gauge from 2 1/2" to 36". Today the most popular is 1 1/2" scale with a gauge of 7 1/4" or 7 ". The 1 " to the foot scale is large enough to ride comfortably, is the largest size which can transported easily from place to place, but is not so large as to be prohibitively expensive for most individuals.

We in the hobby build trains, track, bridges, tunnels, and other infrastructure items outdoors in the real world and have to deal with the same problems that the 12" to the foot prototype railroads do. This makes for an interesting challenge. Many in the live steam hobby do not have their own layout, instead they band together in live steam clubs. In that way much more extensive layouts can be constructed using the talents of all the club members and spreading the track building labor and costs around. In this scale there are two track gauges, 7 1/4" which is prevalent in the northeastern parts of the United States and Canada and most of the rest of the world and 7 " gauge which is prevalent in most of the United States and Canada. Neither gauge is strictly correct for 1 " scale. The correct gauge is 7 1/16". This is one of the reasons many people build to a scale of 1.6" to the foot rather than 1.5" to the foot. For 1.6" scale 7 " gauge is correct. This slight difference in scale is not too noticeable except that it gives an extra inch of interior space in equipment.

The locomotives are powered by steam, batteries, or small gasoline engines. The rolling stock can be made of wood or metal. The type of individuals involved in this hobby are varied. Some construct all their equipment from scratch, some build there equipment from kits of materials and instructions purchased from hobby suppliers, and yet others who not having a machine shop at their disposal - buy machined kits which they finish themselves. The last category of large scale backyard railroaders is the ones who purchase their equipment ready to run.

MDMLW can supply the needs of all the above modelers.

1. Hard to duplicate parts for the scratch builder.

2. Complete kits of materials, drawings, and instructions for the builder with a complete shop.

3. Machined kits for those whose shop doesn’t include a milling machine and a metal lathe.

4. Semi-finished locomotives for those who want the major components done, but are willing to spend time and effort doing the finish work in exchange for a significantly lower purchase price.


We can supply all of the above along with most in between variations. Examine our web site, then tell us how we can meet your needs. Also we have a LINKS page listing other hobby suppliers, periodicals, clubs and any other resources we find which may prove useful.
