Atlantic's works: Portable layout - Scenic details next

[52D]

Why not go a bit radical and power the rear tender bogie with an adapted Black beetle or something similar derived from a diesel. It is probably impractical to power the engine/tender bogie unless a suitablly laid down motor arrangement can be sourced. The front end could then have good solid construction to act as ballast.
Hmmmmm if we can get a power bogie under the cab we would have a booster if the loco was powered as well

Im liking the suggestions that are coming in, please keep them coming.

Looking at the general arrangements drawings in the attachment on the other thread (gawd help us), I think that the loco drive in the County could be used as is with a scratchbuilt body, coupled to a Black Beetle for the power bogie under the cab. The plate frames of the power bogie look sufficiently high enough to hide the Beetle, whilst the running plate of the loco as a whole would give plenty of room for the assembly of parts underneath.

Aaaagh!

Simon, you are a brave man to post that image on this forum and especially on Graeme's thread!!

Methinks you would need 2x D49 bodies.

[Atlantic 3279]

Regarding dimesional pedantry , if that really matters in this case (suffiently to affect final appearance or to spoil the levels of accuracy achievable in other areas): The C7 coupled wheelbase, preserved unaltered in the two C9 artics, was 7' 7", coupled wheels being 6' 9" I believe. Adoption of an ex-Pacific or 4-6-0 chassis with 7' 3" wheelbase and typically 26mm Pacific model wheels (undersize) would probably make the gap between the wheels look about right.
Given that the Hornby 4-4-0 chassis in "long set-up" mode should have 10' 0" wheelbase, I'm wondering what the "short" setting of the wheelbase is. Can you tell us Simon?

On another aspect of uses for Hornby Pacific wheels, I've recently been considering use of one of Hornby's bargain sets of six Pacific wheels as an experimental "budget upgrade" in lieu of the old, deep-flanged Romfords (plain mazak treads on one side too) on a Sam Fay in my possession. I know I'll have to arrange for 3mm bearings in the main frames and find a way to make the existing 1/8" bore Romford drive gear fit the slimmer axle (simple I think), but it could be a real money saver and cosmetically effective - especially in combination with a new bogie from some Mike Edge's etches I bought for use instead of the K's slab.

Any suggestions on how to remove the Hornby wheels from the axles, I need to add a geared axle to one pair I have spare.
This is for another upcoming project which will be a majorish upgrade of a LNER Railroad D49. Amongst other things I hope to use some spare A3 wheelsets with the lovely lining.
It hasnt arrived yet so no idea if both have the same axles sizes or use the same gearset.
Just found the service sheet traction tyres yuk . I wonder if some weight in the body will make them unecessary, time will tell

[Atlantic 3279]

Interesting points about those C9 artics from the RCTS book: For modelling purposes two D49 bodies do seem a good idea. The boiler diamaters should be right and the new cabs were definitely D49 pattern. In reality the two locos had brand new non-standard boilers to give extra steaming capacity so it was no cheap C7 adaptation. Also, unusually, that straight sided extension to the wrapper above the cylinder isn't covering a valve chest - it's just a cosmetic cover for the booster steam pipe elbow.

Mick: I think it is just a case of marking the axle end and the wheel hub to denote the correct quartering and then PULL. I believe the wheel just fits on splines on the end of the axle.

Excellent ,thanks for info.

Given that the Hornby 4-4-0 chassis in "long set-up" mode should have 10' 0" wheelbase, I'm wondering what the "short" setting of the wheelbase is. Can you tell us Simon?

I'm afraid I don't know off the top of my head Graeme, my apologies. If in the "short" setting, it matches the County exactly, the total wheelbase of the locomotive was 24ft and the coupled wheels are a scale 6' 8 1/2''.

[Saint Johnstoun]

The Hornby County wheelbase is set at 34mm which equates to 8'6" so is not really suitable.

I'm wondering if A Pacific chassis could be doctored (remove front drivers and move bogie back and relocate cylinders?)

In which case my shopping list would be.

2 x Hornby D49 bodies.

Hornby S/D China A1 or A3 chassis.

One Bachmann V2 tender.

I'm getting very tempted!

There could be the same problem with the motor as with 2002's 4-8-2 though!

I've been looking at the 'County' for a little while, as the wheelbase is only 1mm out for a D3 (plans spinning in my head)

Really? Hmmm, I've got plans spinning in my head now!

[Saint Johnstoun]

I've taken the plunge and ordered two D49 bodies from EKM. I will see how I can get these to work before moving on to the chassis and tender.

However, further research proves that the modified Pacific chassis will not fit if the original motor is used - the same problem 2002 has with his 4-8-2. However, no doubt ingenuity will provide an answer.

I've just been looking at a motor from the 101DMU/GWR Railcar/Class 73 and it may be possible to alter the chassis to take this - it will also solve 2002's 4-8-2 problem! The rear worm would be redundant of course and the other worm would need changing but if mounted sideways instead of vertically It might be possible with suitable adaptation of the motor mounts.

Tip for removing worms - put in freezer overnight wrapping the main part of the motor in a small plastic bag. It will then come off easily.

St J is the B12 chassis any good for conversion?

[Saint Johnstoun]

It may be possible to use this but the attraction of the Pacific is that the brake blocks are to the rear of the wheels as per the C9. However, I've just dug out my only B12 and this may be a solution although one would have to fit cylinders and connecting Rods, brake gear etc.
