Williams semi-scale Pacific proportions question.

How about an exact Williams model?  The Williams Model: 40801 is 20" long, the scale Pacific is 22" long.  I'm looking at a typical example, the Lionel 6-11334 Crescent Limited Legacy model.

It's actually better than some of the old K-Line stuff, other larger K-Line models are more like S-scale.  I have the K-Line Allegheny, it's considerably smaller than my Lionel scale Allegheny locomotives.

I know it's smaller than the Williams/Samhongsa brass, if it's the one I'm thinking of.  Here's photos of the latest Bachmann 4-6-2, next to the Samhongsa 4-6-2 and 4-8-4:

That said, it's size is very close to what the Seaboard Air Line Class P Pacifics.

Look at the lack of tapering of the cab roof into the cab side(its a SRR cab type). Except for the shortened length(almost no space between driving wheels) and lack of feedwater detail it is a model of the SRR PS4 4-6-2 - based on the USRA heavy 4-6-2.

Much appreciated, one and all. Thank you very much for all the helpful info!

The K-Line Allegheny is a scale model, but is 1:58, as I believe it says on the box. I do believe that the K-line (now WBB) USRA Pacific (and there was a K-Line Mike version) was built to the same 1:58 scale (it's a good model) rather than to 1:48 O-scale.

So - the new WBB die-cast Pacific is a nice scale model; it's just not O-scale, even though it's O-gauge. 

-----------------

I always though that 1:58 (actually 1:56 would be right on) would be the perfect scale/gauge. It would have a gauge of 1". It would be more room-friendly and less unwieldy than O, but more impressive than 1:64 S-scale, and track well. It would have required a new track system (NOT a 3-rail one) of 1", as mentioned. Kadee couplers. Sweet. I would have called in "SO" scale - between S and O.

But no one is ever going to offer a new model RR'ing format again. Ever.

It doesn’t have a name, but there’s a scale occasionally seen in UK of 5.5mm = 1ft, 1:55 scale. It’s usually combined with 12mm (TT) or 16.5mm track for narrow-Gauge modelling, there were a couple of small manufacturers offering kits 

It looks very nice for narrow gauge modelling but I suspect that length would be a problem, especially bogie coaches and longer locos. 

Tri-Ang produced a range of OO coaches in the 1960s which were significantly under-length to suit the 15” #1 Radius which remains in the Hornby range as their standard minimum size, as do the short coaches. In fact Tri-Ang were pretty much the British O27 of their day. 

It’s a pity model railways didn’t go directly to S Gauge, which is half of 1 Gauge (1:32, 45mm). I suppose O was the smallest practical size for the clockwork mechanisms of the time, and for live steam.

If I remember correctly, the current Williams (ex-K-Line) is well detailed and proportioned, but undersized.  The only true way to tell is take measurements and compare with a USRA light Pacific drawing.
