A lot of people in involved in the hobby of model railroadingWhen you talk about HO scale, why do you then add, “OO inthe UK”. The 2 scales are completely different, as you will know. HObeing 1:87.1 and OO being 1:76.I get brassed off with advertisers who list their locos and rollingstock as HO/OO. There is a really noticeable difference in sizebetween 2 items in the 2 scales. I got caught in the early stage ofmodelling and bought a couple of carriages which were listed as HO/OOwhen in fact they were OO and much larger than my HO counterparts.I do believe the 2 scales should be treated quite separately and notgrouped as one.
