Is LGB Uintah Mallet 1:20.3 or 1:22.5

Post by Scott Anders » Tue, 08 Aug 1995 04:00:00



Just saw the NMRA "Large Scale" report in the Bulletin (I'd post a URL
to it, but the "current issue" of the Bulletin in the NMRA home page is
two months old).  It'll be great when (if?) the manufacturers start
labelling as it prescribes.

Has anyone checked out the LGB Uintah Mallets close enough that they can
categorize them according to the proposal?  Basically, it says that the
scale, gauge and fidelity (AAR, Fine Scale, Semi-Scale or Hi-Rail)
should be specified.  The gauge is obviously 45mm.  LGB has been touting
the precision of them and they appear to be fairly accurate so I doubt
that they would be classified as Hi-Rail, but they don't appear be
accurate enough to be AAR (e.g. wheel profiles appear to be standard
LGB).  I'm guessing that they would be classified as either 1:20.3 fine
scale or 1:22.5 semi-scale.  Does anyone have any insight into the
answer?

Agreed, but what if the manufacturer claims one thing and the
measurements show the other?

Unfortunately the LGB Uintah Mallet is nowhere near either 1:20.3 or
1:22.5. I checked a few basic dimensions of my copy;^) and if you
really want to classify it it would be closest to 1:24 semi-scale.

The proportions of the loco are affected in the traditional LGB way so
what one has is something like 1:24 for the length, 1:28(!!) for the
width and something between 1:22.5 and 1:24 for the height.
The drivers are a real disaster as they are much to small. I don't
remember precise radius but they definitely scale to at least 1:28.

Once you stop looking at these details;^) it is a fine modell!

What is also important is that it goes well with the LGB Mogul, and I
hope that if LGB once issues the 0-6-2 Uintah tank loco it will be
equally close to (effective) 1:24, and not to something like 1:20 as
is the case with their 0-4-0 Porter!
