@Bob posted:The PRR 2-10-4 has 69" diameter drivers vs. 64" for the B&LE locomotive. The 5" difference is about 1/8", which I think would really change the look of the B&LE. The huge boiler vs. relatively small drivers gives it a distinctive look.
Not speaking for the OP Bob, but I have a 6” leeway on anything I build, ….if I’m within 6” ….I roll with it, …..I don’t think 5” would crush my spirit, especially if it came down to not being able to run it, and being able to run it …….I’d give up that 1/8” total in a heartbeat,……😁
