Train Models Lovers: Scale Standards for Model Trains

USA, Europe and Britain are the major areas where model train collecting occurs. However each of these areas use different scale standards, much of which is based on historical developments, and even on historical mistakes!

USA
The National Model Railroad Association, NMRA, began to standardize model railway scales more than 65 years ago. NMRA standards are used extensively throughout North America and also by some special interest groups throughout the world modeling US railways.
In general, the NMRA and NEM standards are compatible, but in some aspects, the standards specified by these two bodies are less compatible.

Some of the NMRA scale standards provide alternative specifications by defining some scales either in millimeters or in inches. Another significant difference is that for HO and O scales, NMRA uses the letter O where NEM uses the number zero. That gives the European scale as H0 and the North American scale as HO

Europe
The European Federation of National Model Railway Associations MOROP publishes, in collaboration with model railroad manufacturers, their NEM standards which are used by model railway industry and hobbyists throughout Europe. The official versions of these are published in French and German.

The NEM specifications of model railroad scales cover suggestions for grades, turnout radii, wheel profiles, coupling designs and Digital Command Control and are, in general, scale specific

Great Britain
The main railways in Great Britain use the international standard gauge of 1,435 mm (4 ft 8 1???2 in) but the loading gauge, that is, the maximum height and width for railway vehicles and their loads to ensure safe passage, is narrower and lower than in the rest of Europe with the same standard gauge.
As a result of this significant difference the country has traditionally used its own distinctive model railway scales. These British scale standards are rarely found outside Britain.

S Scale Model Trains


The S-scale, known also as the S-gauge, for model trains is designed on the ratio of 1:64 [that is, 3/16 inches = 1 foot] and fits between the popular HO and O model train scales. It met the demands for a scale which was larger than HO [which was considered too small by many model railroaders] but smaller than the popular O scale thus allowing track layouts to be constructed in smaller spaces.
Although S-gauge model trains had been around since the early part of the century, it began to boom with the advent of the re-designed American Flyer model trains first produced by The A.C.Gilbert Company in Connecticut, USA, during the late 1930s. The famous American Flyer model trains, which had been produced since the early part of the century initially as clockwork model trains, then later, as electric trains, were radically re-designed by Gilbert when he bought the original company. These trains were built to S-scale but ran on standard O-gauge tracks.

Some years later Gilbert introduced another of his radical modifications he re-designed the tracks for the S-scale trains, moving away from the traditional three track rail used in model electric trains to that date.

The three track rail then in general use had the two outer tracks for the wheels to run on with the third, centre track, carrying the electric current to drive the model train motor. The new two track rails made the layouts seem more realistic as they now looked like real train tracks. The development of these tracks to suit the smaller S-scale model trains also allowed track layouts to have curves of a different radius, more appropriate to the re-designed American Flyer locomotives and rolling stock.
 
Many, if not most, of todays S-scale enthusiasts had their first introduction to that scale with the American Flyer when, as a youngster in the 1950s, they received a set as a Christmas present. During that period, the Flyer competed directly with the Lionel model trains of that time and these two companies were the market leaders.

Today the S-scale model trains, including the long-lived American Flyer are rising rapidly in popularity again.

This is the result of the Lionel Corporation, the predecessor of the present manufacturer of Lionel trains, Lionel LLC, having purchased the rights to the American Flyer from the company which had bought the rights from A C Gilbert when his company became bankrupt in 1967.

Lionel Corporation was itself in financial difficulties at that time, and went through the hands of several owners before reaching its present incarnation as Lionel LLC in 1996. But for some time that new company initially concentrated on producing and marketing its own HO and HO27 models and did little to inspire the devotees of S-scale. Since 2002 however, Lionel LLC has been introducing new models of S-scale model trains and heartening those enthusiasts.

There is a range of organizations and associations to cater for the interests of S-scale model railroaders. A peak body, the National Association of S-Gaugers, which is also associated with the National Model Railroad Association, has a very active membership. Their website which provides information on activities, events, suppliers, and archived reference material, also has links to S-Gauge clubs in 29 US states as well as Canada and the UK. There are even two Yahoo Groups S-Trains and S-Scale.

S-Scale model trains, and all the appropriately scaled accessories, are now produced by a number of manufacturers and cater for several different segments within that scale mainly the American Flyer, the standard S-gauge and Proto:64 being the major ones.

After a long and checkered history S-scale model trains are certainly back in vogue again.

To quote Craig OConnell from his S Scale Model Railroading Homepage website:
S scale is one of the fastest growing scales within model railroading today and is growing in leaps and bounds. Why? Because you need only 10% more space than HO to operate, our products are proliferating in the market place and S scale products run reliably, track better and are easily modeled to prototypical accuracy.

There are a number  of people who do not know what Hornby model trains are. But, those people who adore and have passion collecting model trains, they perfectly know what Hornby model trains represent. Actually, in 1901, these model trains were named after a well known person who is Frank Hornby. In the early 1900’s, there were many railways in United Kingdom. Frank Hornby  was actually based in Liverpool and he was inspired by the countless railways and trains that he can see every day in the community. The Hornby company which was primarily established by Frank Hornby became the first trade name for railway productions. These days, there are several websites that a person can find over the internet that has these Hornby model trains being sold to the general public. There are trusted as well as reliable websites that offer a wide range of these Hornby model trains. There are also trusted sites over the internet that offer Hornby model trains set which in...

Train Models Lovers: Planning a Track Layout for your Railroad

How to decide on a?? Track Plan before you build your model railroad layout? When planning construction of a model railroad there are all sorts of possible track configurations and plans to consider. It really depends on the space you have at your disposal and what type of train operation you would most enjoy. Real railroads (prototype) run from one destination to another rather than go around in a circle. In reality, real railroads usually have hundreds, if not thousands, of miles of track to work with. Even in a scaled down form, most model railroads lack the space to fully replicate this, so a degree of adaptation and compromise is usually required. Full size trains often run for long stretches over monotonous landscape, which if reconstructed on a model layout, would be rather boring. To give you an example, the Ghan Train in Australia, runs 1,880 miles across mostly barren desert. Imagine replicating that on a scaled down model railroad ??? it would probabl...

Train Models Lovers: Model Railroaders - Model Railroading

Model Railroaders Model railroading can be a family hobby or it can be the focused passion of any one person. As a family hobby it is a very enjoyable pastime where parents and children can work together, re-creating miniature worlds that can be based on an existing railroad or one from a bygone era. For the really committed individual working alone it can be a time consuming, often expensive, and often frustrating hobby. The trains used in model railroading are not merely toys. Rather, they are carefully detailed, scaled down models of current real-life locomotives and rolling stock or, more usually, models of those from important railroads in railroad history. Not only does a model railroader spend time and money on setting up tracks and ancillary equipment for their chosen trains but also spend considerable time and money on building realistic landscapes to provide an authentic setting for their model railroad.
