3-Rail Scale Model Trains

3-Rail Scale is model railroading in O scale that strives to achieve the most true-to-prototype realism possible with locomotives, rolling stock, paint schemes, scenery, operation, and other aspects of the hobby, while still using 3-rail O gauge track. This includes the use of scale (Kadee) couplers, and other modifications that make the model as close to prototypical as possible.

How wide is O gauge train track? ›

A circle made of eight pieces of standard 45-degree curved O gauge track will have a 31 inches (787 mm) diameter. A circle made of 8 pieces of 45-degree curved O-27 track is smaller, with a 27 inches (686 mm) diameter. Full-sized O cars sometimes have difficulty negotiating the tighter curves of an O-27 layout.

Can O gauge trains run on 027 track? ›

A: O and O-27 use the same width straight track so O-27 trains can run on O Gauge track and in some cases O Gauge trains can run on O-27 track. The primary difference between the track from an appearance standpoint is the height of O Gauge track compared to that of O-27.

How many cars can an O Scale locomotive pull? ›

Man, you can put as many cars on the trains as you want to. When the locomotive's had enough it'll tell you by slipping its drivers and not pulling at all. I put as many on as I can get away with, on my Christmas tree loops I've even gone so far as to have the caboose about a foot-and-a-half from the locomotive.

Which is better, HO or O Scale trains? ›

What is the diameter of an O gauge track circle? ›
