Locomotive Plans

The following is a list of available plans for Gauge '3' and 2.5inch steam locos. It is probably incomplete -but should serve as a guide to what could be built or used as a basis for modification.

These are plans from the Internet and are free to download. They originally come from NZ and are produced by a Dutch settler..


Working with Plans...

The first thing to remember is that the plan is NOT the model. It may sound a very strange thing to say but if you think about it -it is true. The plans may come from several era and designers. This means that things that the designer KNEW to be common and easy to get -may no longer be... If you have a set of plans from LBSC or HG then you would expect the dimensions to be in Imperial, most likely a multiple of 1/64th of an inch and the sheet thickness to be in SWG with threads in BA or ME. But even nowadays with plans drawn this century I am still finding material specifications in Imperial... For one set it specified an Aluminium U profile section of 1/2" x 1/2". My only sources of supply were the US or Poland. Remember that Frame Plates are designed to hold everything and take the weight thus the thicker metric sizes are not the same as SWG and this cuts down on spacings.

When three of us set out to make a model from the same set of "hand me down" plans our approaches were vastly different. One had drilled and tapped holes with BA and smaller size BA nuts. One used bored holes with threaded rod and stud set. The last welded and soldered. mounting the pony trucks produced three different solutions as well. A triangle with and axle, Two front mounted radial bars to a swinging axle, and finally a Radial axle with rose joints... The ends were, carved from Balsa, Made from P40 and P38, and Bashed from sheet metal. Not one of use used the "blow moulded" noses available.

A point to remember with older plans is that they might have been scanned from the originals and then the scanned image cleaned up and stored. The printout that you receive will probably be printed on A2 paper. Although the top of the plans may say "Full Size" they will not be!!!


Guide to the Designers

HG.

Henry Greenly was perhaps one of the best model designers of his era. But his designs suffer from the fact that he expected the builder to understand what it was that he was building and how it should work, e.g. a steam injector. He also assumed that the builder had access to a near complete model engineering workshop and the tool required would be already to hand, as would be the knowledge of how to use it. His designs show a high level of calculation and some basic empirical design. His model designs are well trusted with the plans, parts, and castings for them -still available now.

THE MODEL LOCOMOTIVE; ITS DESIGN AND CONSTRUCTION A PRACTICAL MANUAL ON THE BUILDING AND MANAGEMENT OF MINIATURE RAILWAY ENGINES

The last one on the list is I believe one of the greatest books on Locomotive design ever written and I have even used it to design Diesel bogies with.

LBSC.

Lillian Lawrence had a style of design that was only surpassed by his instructions on how to build his models. It takes time to get into the mind of LBSC but once there you understand his thought processes. More than HG he worked from an empirical methodology. His models do tend to look rather crude and somewhat shabby but the techniques and parts from LBSC model are nearly always the same as those used in the next one. This enables suppliers to have a good market and high stock levels for his designs. The drawings tend to need some "thought" as he did not always note down some vital things and he expected the builder to "know" how to do this -from doing his previous builds.

Simple Model Locomotive Building: "Tich".

Although "Tich" is about building a 3 1/2" loco, it is made from "scrap" 2 1/2" parts. The book is very common and serves as a good grounding on how LBSC "saw" his models and designs. The techniques found in there are reliable and proven. There is very little technology or calculation involved in his work -but he expected a high level of machining.

Martin Evans.

Probably more of his designs are running than any other designer. The drawings are "clean" with no mix of various dimensions across the drawings. They are all imperial and use BA and ME threads only. As yet there are few suppliers for spares and castings.

The last one on the list is on a par with the book by HG but the emphasis is on the larger "tractive" scales

Chris Barron.

The drawings are first class, cleanly dimensioned and a list of suppliers is enclosed with the plans. His plans suffer from the fact that some of the sources and materials listed in the plans are now very hard to find. His plans are mostly imperial with BA and ME threads.

Earnest F. Steel.

More famous as the Son in Law of HG he did in fact produce some designs chiefly for diesels and electrics. The AC electric rectification techniques may now be classed as historically interesting (and highly unsafe by modern standards!) but the designs are of good quality and well documented. Interestingly his drawings are in metric only.

Earnest F. Carter

Not a designer of complete locomotives -but the things that you need on the locomotives. He may be regarded as a source of designs -rather than a designer. His works are clear and precise and all his dimensions are in Real World sizes -he considered it up to you to make the reduction! I would say that most of his work covers the late 40's to early 60's and there are some interesting things in his books for the reader to find.

Modding.

This is taking a design and modifying it for your own needs. Some designs lend them selves into being modded into other locos that are not on the list... My "Mod" is based on the LBSC design called "Southern Maid". This has a simple 0-6-0 layout with a six wheel tender. It is classed as a simple loco for a beginner to build. What my loco now looks like would give poor Lillian a heart attack. Family history shows that part of my family worked for the MAV (Hungarian State Railway) and the KKStB (Austrian Imperial Railway) during the period of the Austro Hungarian Empire. Their chief designer was Golsdorf -who before visiting England produced some singular and unique designs. To the standard design for "Southern Maid" I have added a Double dome and Clench tube steam drier and a water tube boiler of the Brotan Filaovits type. These give the boiler the classic MAV "hunch backed" look. The front pony axle to give the correct 2-6-0 wheel configuration is easy. This would have been better built as an electric loco rather than live steam, as building a Brotan boiler is not for the faint hearted!

Elsewhere in the main directory you will find instructions on how to build a 0-4-4 loco and how to produce differing locos from the same starting point. The G3S loco project "Venture" uses the same principle -but there is one main avenue to travel, an LNWR Cauliflower, but it can also be made into two other locos.
