Welcome to

the Double O Gauge Association

Website last updated January 2022

We are the organisation catering for both new and veteran railway modellers working in 4mm scale using a track gauge of 16.5mm – the most common for models of UK prototypes.

To find out more about us, visit the About DOGA section.

Perhaps you would like to read our magazine “The Journal” or purchase some of the products we have developed to help railway modellers working in 4mm scale using a track gauge of 16.5mm at the DOGA Shop.

If you’d like to meet us, check out our newly updated Events listing.
