GT3 Gas Turbine OO gauge Model


The History

The GT3 was designed and built in 1958 by English Electric at their Vulcan Foundry works in Vulcan Village, Lancashire.  Built on a strengthened steam chassis and tender with a Gas Turbine power source.  The locomotive had a designed maximum speed of 90 mph (140 km/h), weighed 123.5 long tons (125.5 t), and was painted in a lined Beech Leaf Brown Livery, earning it the nickname "The Chocolate Zephyr" amongst railway enthusiasts. Underframes, grilles and the front access and cab doors were painted Brunswick Green with lettering and lining in Orange.

The plan going forward

Many thanks to all those who have signed up to purchase a model of the GT3.  Deposits are now open (link is below).  There will be 3 payments for the DCC Ready and 4 for the DCC Sound version.

I would like to give a special thank you to Tim Coles, without who's participation this would have never happened.

How does the payment plan work?

There will be a request for an initial deposit of £50 to secure your model, then two other installments as the project proceeds (three additional installments if you order the sound version). We are using crowdfunding to fund the project.

Crowdfunding is the practice of funding a project or venture by raising small amounts of money from a large number of people, typically via the Internet.


OO & N DCC ready £185

OO & N DCC sound £285

All plus shipping.

What is the expression of interest?

Please only make an ‘expression’ if you are certain you intend to invest in the model development, as your ‘expression’ may be the one that puts the model into production. Numbers are tight and anyone who drops out or in fact does not have any intention of ordering will be doing the whole project a disservice. Pre-orders will not open until the ‘expression of interest’ level reaches a break-even figure. Once that limit is reached, we will open the system for pre-orders secured with a £50 deposit.

What is the proposed delivery schedule?

As we know with all suggested delivery schedules these are subject to change and not written in stone. We will be keeping ALL customers informed every step of the way. Expected May 2020.

What sound card are you using?

We will be using the LokSound V5.0 with the EM2 speaker. We will be recording the turbine from the loco on the stand. It will be altered to sound more lifelike.  We are evaluating the Loksound V5 currently.

Who is building the model?

We have commissioned a manufacturer who has a great track record and who has built a reputation on quality. 

Can you post world wide?

Yes, absolutely. We have customers from around the world.

How accurate will the model be?

Whilst the original drawings are not available and were probably destroyed at the time the locomotive was scrapped, we have been able to develop what we believe are very accurate renderings. This has been done by researching the records at the National Railway Museum. We also studied some of the available photographs and interviewed some of those who worked on the locomotive.  This work was undertaken by Tim Coles in order to build his working model in 5" gauge. This example of the model subsequently taking top awards at Model Engineering Exhibitions.

What is the warranty?

We will have the standard one-year return policy.

Files coming soon.
