It is the only time in my long venture,
into modeling THREE foot narrow gauge in the nineteenth century,
that I have found a scale that has no holes:
1. An affordable RTR 4-4-0
2. Available affordable almost RTR cars.
3. Plastic people making them convertible and metal ones to fill in other areas.
4. Wagons and animals
5. Affordable buildings and detail parts
6. Most important readily available CHEAP track that looks like narrow gauge track and is CORRECT three foot gauge.
7. Fits in an HO space
8. Mechanisms, drivers and detail parts to make locomotives
Only 1:55n3 offers all of the above.
As the man once said, "It is great when a plan comes together"
Harold-looks like an interesting scale. You mentioned that "only 1:55n3 offers all the above" things like figures, structures, locos that convert, track, etc... 1:35n2 offers all those items also and maybe a little less cost. 1:32 Autos & trucks (Model T, Whites, etc.) may be had for 10 bucks. Any available HO or On30 locos can be "scaled" for use and detail parts are available. Many On30 plastic freight cars are OK as are HO & On30 trucks. Buildings are available from military model companies as well as many, many detail parts. Scratchbuilders supplies are available also. If one doesn't want to handlay track, Peco On30 track becomes 1:35n2 and in the larger scale, the big hunky ties look correct. And the biggest plus (for me) is that in this larger scale, onboard batteries and radio control are adaptable-getting rid of all track wiring and it's problems. I just wanted to point this out.
