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... https://www.scalefour.org/forum/viewtopic.php?f=20&t=5583 ... 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.
This is the early A0 H1 Parallel Boiler & Firebox B. Essentially it is a freelance variant. The only difference is the firebox profile and the safety valves. The original safety valves are included but you will have to cut the newer smaller ones off first to fit.
It will fit any of the A0 running plates and can be used as part of the kits. Or maybe you could use it as a stand alone piece for a scrap yard?
The smokebox is provided. The boiler has holes designed in for locating the hand rail pillars and hand rail. Hand rail pillars are usually 9mm's in diameter and the wire to go through them is usually 0.45 mm's.
The safety valves need a teeny bit of wire adding down towards the cab.
To make the main pipe that usually goes along the boiler you will need some brass, nickel silver or styrene rod and split pins.
Due to the parallel design that is also pitched slightly lower this boiler will not fit a modern Hornby Gresley A1 RTR loco drive Chassis, it will fit the older ones with X04 motors and the tender drive types.
