Given 5 bricks=6 ft (a minifig), then 5 bricks is if anything, midrange.
engines I have data on here- 8P (DoG) was 74”, a UP FEF was 80”, J is 70”,
German 05 is 90”, NYC J3A 79”, GWR Castle 80”, German P8 69”
So, a 5 stud diameter looks about right to me.

How many of those are high speed passenger locos though? In terms of
population density, low speed freight locos were much more predominant and
they had smaller drivers.

Most of the above are passenger- DoG is a one off. But, the P8 was a bit
more than a make up- there were 3800 of them built. :). Also, when you look
at the UK, 9F’s have a 60” dia wheel, which is small for most mainline locos-
and I am assuming most people here don’t model 0-4-0 tank engines with 30”
wheels :)
Go stand next to any loco, and you will see what I mean- they tower over most
people quite nicely :). Even a CP 0-8-0 that I was near recently- the wheels
are not as tall as I am (6’) but they are still quite close.

Speak for yourself... :-)
The other thing this ignores is that a lot of steam trains (the Castle class
certainly) had the main drivers going up through a slot in the sole-plate.
That’s why they have wheel arches, and why British steam locomotive nameplates
are all curved, to fit the arch.
This is very hard to model in Lego, particularly if you want the wheelbase to
flex through corners. That’s why I prefer a smaller wheel, so that it can pass
underneath the body. I certainly wouldn’t want to try with anything larger than
what Ben has proposed.
