Back around 2000 I switched from HO to On30. At that time there was very little ready to run equipment so everything was kitbashed from HO or scratchbuilt. Built a lot of rolling stock, mostly 4 wheel ore cars and some locomotives based on HO drives. Burned out on it after a few years. Here's a few of the cars and such I built back then. The old layout is toast, so I set them on the current "dual gauge" O-27 layout! lol
