British trains are generally tinier than other railways. But I don’t think that’s why the British went to OO on HO track. According to an AI Google search (Wikipedia says those are never wrong):
OO gauge (1:76 scale) uses HO gauge (16.5mm) track because of a historical compromise in the 1920s-30s. Early electric motors were too large to fit inside correctly scaled 1:87 (HO) British locomotives. Manufacturers increased the body size to 4mm/ft (1:76) but kept the 16.5mm track gauge to ensure compatibility with existing, popular track systems.
Why OO Uses HO Track (16.5mm):
Engineering Limitations: Early DC motors were too bulky for narrow British loading gauges.
Scale Compromise: While the trains are slightly larger (1:76), they are placed on the standard 16.5mm track, making the trains technically sit on a narrower gauge than they would in reality.
Component Compatibility: This allowed British models to use the same off-the-shelf track (often labeled "HO/OO") as European and American manufacturers.
Historical Choice: Frank Hornby decided to keep the 4mm-to-the-foot scale for British trains but kept the standard HO track gauge, creating the "OO" standard popular in the UK.
While OO trains run fine on HO track, the trains are about 14% larger, which is why they appear slightly larger than HO scale models.
If by “locomotive” you mean doors in my house, and if by “tech” you mean my abdomen, and by “scale” you mean width (or gauge!), then you just described some modifications I need to make to the house.
Which is why I ordered the enchilada a la carte, today.
Hi Gregory, hopefully I’m not intruding but I would approach building such a bridge using thick card stock and Das, see a few images below of a small 1/72nd bridge I built for a diorama. I’d simply scale things up,.
Sorry. No can do. Took my ex-girlfriend to Chuy’s last night. Other couples ordered two enchilada or two taco dinners. For a dollar more, we shared this:
Swapped out the refried beans for green chili rice. Saved 40 calories!
Of course, we did do a 5K earlier that day. Even took the doggo. Even though she’s technically of Mexican heritage, we brought no leftovers home.
@G-man69 this thought occurred to me on another project and is perfect how you did it. I’ve thought of doing 3x5 note cards and building a bridge like that, maybe this is my sign to.
I used to take my sheltie with me everywhere I went in El Paso. One time before I had him as shaved for the summer, we were at a little too long and I had to carry him home. It was mostly uphill. I wish I had a medal for that. But he was my little buddy so, no pooch left behind.
