This section is aimed at the experienced Gauge 3 model engineer and the projects covered are definitely not for beginners. They cover some orthodox model engineering practices and some rather more exotic concepts. This route is definitely aimed at the more adventurous!

If you are reading this, then you like a challenge. During the history of the railways several designs have come and gone -some due to "fashion", some for sound engineering principles, others due to the inherent problems in the design... There are still several ideas espoused by designers that did not appear in production locomotives or even leave the drawing board. We would expect you to have some detailed knowledge of model engineering and modelling. I like to term myself as, "A Modeller who has to use Model Engineering to make his Models". At this level you will need a lathe or have access to one. A milling machine is definitely icing on the cake -but everyone loves eating the cherries...

Here we would expect you to have detailed knowledge of tools and how to use them. You may not have many of them, but the ones you will have, you will have bought as investments -rather than purchases. Although the G3S does not have a precise dictionary of techniques there are several members who are adept at "fudging" what you might need to make.

The principle problem with the Gauge 3 scale is that it is, "just big enough", to do things with. There are two members working on Diesel Locomotives. One plans a "Fell" D/M locomotive while the other a "Peak" D/E locomotive. Careful measurement will show that a gas turbine loco IS possible. But the actual loco may be several decades away. Steam Turbine locomotives of either of the three main types are possible. Modern type steam systems clad in early steam garb are also possible.

This is the Route of the Schemers and Dreamers!

Although this sounds like the arena of the model engineer I would say that it is not. Your levels of skill at this point enable you to think differently. You will look around and see beautiful models of Brittanias and the like and want something different. The Shay, Climax, Heisler, Rimataku, Fairlie and Golwe locomotives are unknown at G3, despite the facts that they were designed to be capable of very tight cornering, similarly most of the locos you will see on G3 tracks are of UK heritage. This does not reflect any bias -it is simply that the majority of plans for G3 locos are of UK types! Given the requirement for less than normal curves it is curious that articulated designs are rare other than the "Boxes on Bogies" of the Diesels and Electrics.

Here are a few places to look...

A place to look for ideas would be "Locomotives that never were" although this is getting hard to find. Ideas and drawings abound in the "Special Edition books" of the periodical "Locomotives International" but again these are becoming rare.

You have now reached the end of the Beginner's Pathway.

Using the G3 Wiki.

You can now use the "search" facility at the top right of the page to find specific information. Alternatively there is Main Index -which will take you to the homepage, where the contents is categorized and, by following specific links, you can browse the articles.

Care has been taken in the preparation of the material but, inevitably, there will be a few errors, since there have not been the resources available to check everything in the available time. Very probably some of the "Known Facts" are in error and we hope you will be able to expand and correct the information held here. If there is something that you feel should be included or corrected then you may use the submissions portal or go to the G3 Forum and post a message on the dedicated G3 Wiki board. Any complaints as to copyright or similar issues should be sent to .

The Authors hope that you enjoy using it -as much as they have writing it.
