Shopping tips
- Prefer listings that clearly say HO scale (1:87), not N or O.
- Check DCC / sound in the title if you need decoder-equipped power.
- For road-specific models, add the railroad name to the eBay search after you land on eBay.
- Brass and limited runs: read seller photos and return policy carefully.
