The general advice is that you don't run engines on anything less than a second radius curve (438mm or 17.25 inches) in 00 gauge (double the measurement for 0 gauge and halve it for N gauge).
How wide is OO scale track?
OO gauge is one of several 4 mm-scale standards (4 mm to 1 foot, or 1:76.2), and the only one to be marketed by major manufacturers. The OO track gauge of 16.5 mm (0.65 in) (same as H0 scale) corresponds to prototypical gauge of 4 ft 11⁄2 in, rather than 4 ft 81⁄2 in standard gauge.
What is the tightest Hornby curve?
I've shown the extreme of the R605 (this is the tightest curve in Hornby's range and really only suitable for the smallest models nowadays like 0-4-0 shunters) and the R609, the 3rd.
How wide is a Hornby platform?
The width across the foot boards on the Hornby coach is 36 mm. These foot boards taper (like the real thing), so this measurement is at their narrowest point. This 36 mm represents an offset of 18 mm from the outer edge to the centre line of the track for 00 gauge.The width across the foot boards on the Hornby coach is 36 mm.

The standard is different from British 00 gauge (which is popular in Great Britain), as it utilises 19mm gauge track rather than HO scale 16.5 mm (0.65 in) gauge track.https://en.wikipedia.org › wiki › American_OO_scaleAmerican OO scale - Wikipedia.
What is the tightest radius?
Modeling Scale Minimum Radius
--------------------- ------------------------
HO Scale 15 to 22 inches
HOn3 Scale 15 inches (narrow gauge)
S Scale 20 to 30 inches
O Scale (Toy or O-27) 13.5 inches
