If I have a Garden-scale train layout in my back yard, could I get away with putting a Z-scale layout in the back yard of one of the G-scale houses, suggesting that the G-scale house has its own G-scale layout in its yard?
Would the raios be close enough, or would the big boys mock me for not being true to scale?
I agree, it would be neat. However, I think the Z scale trains would be about twice as big as a G scale train on a G scale layout. Feel free to correct my math if it is incorrect:
G scale = 1:22.5
Z scale = 1:220
220/22.5 = 9.77 which would be a little over twice as big as 22.5
At the NMRA show years ago in Philly, there was a G scale indoor setup on display and one house had a Z scale train set up running around the yard as a ride-on scale size train, it worked out pretty well.
T is nearly half the size of Z. That it runs is almost a miracle. All displays of it I have seen have been simple loops. I doubt you could operate with it, but for a display in the backyard of a G scale house - it should work.
