Product Description
General A0 range overview.  Product descriptions below this...

The A0 is a 'what if' 4-6-2 Pacific locomotive design that was as far as we know drawn by Sir Nigel Gresley in 1915 and a couple of known redrafts afterwards.  A0 is not a real designation but for identification I coined it years ago when helping with the formation of two essays on the A0 and the possible development of it into other rebuild combinations.  I personally believe along with others that it may also form the basis of certain Railway Series characters.

For an in depth explanation of what the A0 is with photographs please check out the following link...
... and please also check out the aforementioned essay links WITHIN the link for a full understanding.

The wheelbase of the A0 1915 drawing is...
6'3" + 5' 3" + 7' 0" + 7' 0" + 8' 0" - However the Gresley A1 is...
6'3" + 5' 6" + 7' 3" + 7' 3" + 9' 6"

For this reason the SCC A0 range has been designed instead to fit the A1 wheelbase so they can still fit  RTR and kit chassis.'

The SCC A0's have been designed around three different Hornby Gresley A1's (bodies & chassis) to ensure as much compatability as possible between them.

What is offered is full locomotive body shells and also as another option the shells split down into kit components so you can combine them into various combinations yourself, even more combinations than the full shell options will be possible this way. 

For the kit route the parts will be easier to prepare and clean the surfaces for painting, also if you order just a running plate for example then you could use your own A1 body and cut out the relavant bits to fit the plates, used this way the items can be used for kit bashing purposes.

Certain configurations will require you changing cylinders and valve gear, or at least modifying them in various ways but the items in question will point you to the suggested changes in the product descriptions.

Product Description...

This is the A0 - G1 Pacific full loco shell.   This is one combination of the A0 Pacific composed out of the  A0 range components.  

NOT ALL A0 Pacific combinations will be available already made up as a full shell, only a few so please plough through the range to find the combination that best suits you for any other possibility.  The modular design of the A0 range has been designed with a mix and match nature so consider these full shells as a non essential bonus!  

One of Gresley's redrafts removed the originally proposed parallel boiler and replaced it with the Gresley tapered boiler like on the A1's, further more this drawing also showed angular cylinder covers at the front of the running plate.  The apparent 'Final' draft saw the angular covers replaced with elegent swooping curves such as on Gresley's Prototype 02 locomotive and also likely was the inspiration for the curves seen on the Railway Series Character Gordon.  This version also has the Gresley cab in place instead of the drawn Ivatt one.

Buffers are sprued inbetween the chassis and the various cylinder covers are joined together.  Carefully cut them out and clean the edges and they can then be glued in place for a strong join, or you could provide them temporary to change the look.  The reverser lever is in position under the running plate, however ideally you need to extend it with brass or plastic section to go through the plate into the firebox, for printing toleranc risks it has been omitted here.

You have a choice of two different cylinder cover profiles for the centre of the running plate front.

Under the running plate you will have to locate where the screw goes to fix the chassis if using a Hornby A1, just position the chassis and mark it then drill a thin hole, the material whether WSF or FUD will self tap. Originally the holes were designed in yet the positions of the various Hornby versions moved slightly making it too difficult to ensure they will work with every version. 

The running plate has a main height set at a LOW position.  This is important when considering what cylinders and valve gear changes may be needed, see below.

If using Gresley A1 cylinders and valve gear (as suggested for these particular versions) then the area above the Radius Rod and Expansion Link will need remodelling slightly to account for the fact the running plate in this area is lower than on a standard Gresley A1.  The best way to explain the modification is thus:  If you imagine looking at the locomotive head on, then for Hornby valve gear, from the edge of the chassis block the bracket usually comes out roughly 1cm and then goes down to the valve gear; you need to tweak it so that it goes down immidiately from the chassis block edge and then goes out to the valve gear instead, being careful not to foul the wheels.  If you need a picture please email me and I'll do what I can!
