Minimum radius for a Bachmann 4-8-4?
#8
You can get 63 x 54 with 10 straights and a circle of 18" R. 2 straights in each end for 54", 3 in the sides for 63".
The actual space required is a couple of inches more.
22" radius might get there - one straight in the ends and two in the sides.
Don't know why they'd measure it that way, though.

In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.
