Hattons Originals O Class A4 4-6-2

Hattons Exclusive locomotives in O gauge developed in partnership with Heljan

 

Hattons, in partnership with Heljan, are producing a range of newly tooled LNER Class A4 4-6-2 locomotives in O gauge. A number of variations have been produced covering the lifespan of one the world's most iconic steam locomotives in a selection of LNER and British Railways colour schemes. We are also producing unnumbered variations, which enables you to run exactly the locomotive you wish to, with accurate tooling variations ensuring they are as prototypical as possible.

Cabside Handrails:

Our models of the Class A4 are supplied without vertical cabside handrails, due to an oversight in the design process. This was discovered too late in the development to amend the models, and we have been unable to source suitable parts for customers to fit these themselves. We apologise for any disappointment this may cause but we are unable to offer suitable parts at this time.
 

Detail Pack:

A set of additional optional parts have been listed as supplied separately with the model, but many of these parts have been pre-fitted to the models as part of the production process.
 
A correct summary of the listed parts and their status is below:
 
Part Number and Name
Status
1. Fall plate Included in pack
2. Coal load Included in pack
3. Valances The correct valances for each model have been pre-fitted during production.
4. Running board supports. These are pre-fitted to appropriate models with cutaway valances. Models with full valances do not require these parts.
5. Brake Rigging Included in pack
6. Coupling Working coupling, can be used to connect locomotive to appropriate rolling stock.

Prototype Information

Following on from the success of the A3, and at the insistance of the LNER publicity Department, Nigel Gresley revealed his next class of high speed express engine in 1935.  They were introduced, like the A3's, for the long distance, high speed, runs on the ECML to which they settled in very quickly.  They were an almost instant success, building on the foundations laid by the A1 and A3 classes with the added streamlining both of the outer casing of the engine and a lot of internal components.  In 1938 Class A4 4468 'Mallard' set the world steam speed record of 126.4 mph on Stoke Bank south of Grantham while running on a trial service with a dynamometer car (for recording speed etc) and 6 standard coaches.  

During the war years it was found that the valances covering the main running gear was hampering quick maintenance that on other classes would be relatively easy.  The decision was taken to remove the valances completely to aid general servicing with the intention of restoring them at the end of hostilities, however this never happened and for the rest of their lives they ran without them.  The only other major change to the look of the locos came with the fitting of double chimneys, although with the abundant streamlining this was less obvious than on other classes.  The A4 locomotives started to be withdrawn in 1962 with the final members lasting until 1966.  Luckily 6 have been preserved, including Mallard and 3 others in the UK, 1 in the USA and 1 in Canada.
