@Steve Tyler posted:AFAICS, York is all gauges, with no higher percentage of O scale than the Timonium show IMHO.
You can find nearly all scales/gauges at York, but O is the biggest gauge by far. If you are talking 2-rail O scale, the percentage may be similar, but I'd still bet you can find more at York. I go to Timonium at least once a year, and York twice a year. Timonium is a great show, but for someone looking for O gauge, it really doesn't compare to York.
