Odd, my conversion of 4' x 8' is 1220 x 2440, hence my earlier ribbing of a certain article series co-author (and my suspicions of the response whenever I might see him next.).
I believe the BL/G is probably the latest modern loco I'd run on this board and I didn't know about the radius restrictions on the 38 and R class, as they're on my wishlist, now I'll have to add more four wheel stock to it and think of a different appropriate steam engine.
Currently, there's only three Insulfrogs (doubleslip, point & 3-way) in use, everything else is Electrofrog. Ayep, I have an Electrofrog 3-way that's yet to be wired up correctly, but I've had minimal issue running trains through most sections after adding more power track feeds. I suspect that AWG #22 single strand hook-up wire is insufficient for DCC power bus usage.
