And now for something completely different!

It is the same width as the Roundhouse L & M model but 50mm longer and 15mm taller. The main issue will probably be the over-hangs on corners. The height difference appers to mainly the tall chimney and the whistle on top of the dome. The chimney could easily been shortened and the whistle removed.

Many people forget how much bigger 2'6" locos are compared to 2' gauge especially those on colonial lines. The Bachmann consolidation is actually a 2'6" gauge loco from a Mexican line and that it at a smaller 1/20.3 scale and it is still way larger than the Roundhouse Sandy River 2' gauge loco.

It should look fine with Accucraft W & L or IOM rolling stock although the American Accucraft rolling stock would probably look better.
 
Having read Marc Horovitz's review of the original Argyle loco I think it possible that Accucraft UK may of listed the scale wrong for this loco as they did for the new US geared loco. I need to check the dimensions again but I think they are the same and the Marc states it as 1:15 same as the Accucraft German 750mm gauge models. This is makes it more interesting for me but may detter those who insist on 16mm scale. Having said that if it was scaled up it would be far too big to run on 32mm gauge track.

Maybe someone with access to dimensions of the real loco can check to see which website has got it wrong? Is it 1:19 or 1:20.3 scale?
 
Chaps,
The scale is 16mm. The model scales to 490mm to the tips of the pilots, which is a tad longer than the 30' 10" on the PB web site (which may be measured between the couplers). The pilots actually are slighly different between the various preserved engines as well.
I noted in the last page some of the other critical dims. As noted, the 16mm scale works better than 15mm scale when applied to 45mm gauge. At 16mm, the width over the cylinders and outer face of the chassis matches prototype and is not widenned. At 15mm scale the chassis has to be widenned (to effectively a 3' gauge loco), which spoils the hunkered down appearance of the prototype. The model however will work fine with other 1:19 stock such as the W&P coaches as well as the 15mm US stock.

Steve,
The original production was at 15mm scale , this new model is 16mm/ft.
I built them to 15mm/ft to roughly match with LGB stock as almost nothing else was available then , times have changed in 20 years!

It does not bother me if 15mm or 16mm scale but I'd assumed that it was the proven design not an entirely new model.

It does make it the largest 16mm scale tank loco available (excluding Garratts) even bigger than the Roundhouse L & M locos and much taller than most 16mm rolling stock. I hope the the change in scale to keep the frame spacing does not mean that there are other more insightly compromises to keep it running on tight radius truck.

Are the dimensions to buffer beams and cab roof or over couplers and to top of whistle?
 
I wonder if anyone will do the the 2-8-2 variant of this design supplied to several European 750 / 2'6" gauge lines?

They are big locos... checking out the Puffing Billy site reveals data pages such as this:

Scaling at 16mm/1' shows the Accucraft/Argyle dimensions to be about right for length over cow-catchers and height to the whistle top. The prototype is 10'10" tall! There were some very similar locos in Norway.
