Reply to "British O Gauge - Key Differences?"

SundayShunterOGR Forum Member

Strictly speaking the standard 32mm gauge is slightly narrower than scale for British O. For absolute scale accuracy some modellers open the gauge to 33mm, ease out the back-to-backs & use scale flanges on wheelsets. This is known as "Scale7", & is the UK equivalent of Proto48.
