Since the trains are just smaller versions of O scale, running on "narrow gauge" track, I would use the O scale standards to be safe. You might also check the NMRA website.
For Ho it is two inches apart on Straight modules 5" & 7" on centers from the front of module . If I remember right .
for On30, I would guess 2 & 1/2 min on straights .
2 1/2 in is 10 scale ft, a bit tight. NMRA recommended clearance for pre-1920 equipment is 12 ft, 3 actual inches. On curves the track separation requirement can go way up, depending on your equipment (e.g. a 2-6-6-2 requires more than say a 0-4-0 Porter)
Yeah, it all depends on your loco and rolling stock. There used to be a demo layout at Caboose hobbies in Denver with something like 8 inch curves. All they ran on it was the little porters and mines cars though.
I am pretty sure most of the On30 stuff is meant for their train set track, so IT CAN run on 18 inch curves. The real question is: How decent does a 2-6-6-2 look on 18' curves?
