These locos still had the wheels below the plate. In fact, the plate looks
disproportionately high to accommodate them. The problem with the
wheels-up-the-sides approach is that it fixes the body to the wheels at the
centre point of the loco. When it goes round a corner, the front and rear
can stick out an awfully long way. You need a lot of freedom of movement on
the front and rear trucks, and plenty of space on the outside of your
curves. Most layouts allow room inside the curve, for long carriages, but
you'll have to check the outside too. My first attempt at a large loco (the
green 2-6-2 in this picture) uses four fixed wheels (the back four are
fixed. The front two form a bogey along with the front pair of guide
wheels) and it swings out a lot on corners:

With this model (Lawrence Wilkes' photograph), I made a 4-6-2 with a motor
on the front, a floating bogey of four big wheels, then a bogey of 2 big and
2 small at the back. The rear one is on a forward/back sliding pivot. It
follows the line of the curve much more smoothly than the previous model.
Even though it's a longer locomotive, it doesn't stick out anywhere near as
much.

I think you have to have wheels still small enough to go under the plate.
As for dark red, I was thinking of Caledonian Railways. An obscure one I
know. LNER also used to paint their hubs green. But, as long as I could
get black ones, I'd be happy.
