After further research of your comment about the correct scale descriptor for standard gauge on 45mm track being Gauge 1, I did a quick look for anything for sale in that scale.
Sure enough, there was a
live steam market in the UK, but I also found that Maerklin do a range of track powered Mfx/DCC gauge 1 models. The only problem is they seem to be very up-market metal construction jobs - priced up around the 4000 Euro mark.
Still, it shows they
do make several models at this scale for track power, so maybe they could be enticed to expand that range? Just a thought.

Or, maybe the people that make live steam models in the UK, could be persuaded to also make track powered models? I get the feeling there might be a bit of "that's beneath our dignity" going on here, but hey, I could be wrong!
There just seems to be a hole in the market, that no-one seems particularly interested in filling. Ie an equivalent market to the one that exists for track powered G-Scale locomotives on 45mm track,
but at Gauge 1. ie standard gauge track powered
affordable models in the same way we have had narrow gauge affordable models from LGB et al for many years. [I guess 'affordable' is a movable feast, but I think you can see what I am getting at.]
I still wonder whether the LGB models of US locos, such as the Mikado and the Moguls, are narrow gauge, or not. Did those prototypes run on narrow gauge lines in the USA? Or, are they just not properly scaled, when compared to their narrow gauge European locos?
Whatever, I have examples of
all of these, and they look OK on my otherwise G-Scale layout. But, as I say, I don't use them all at the same time!
