My test track is only 10 ft so I decided to make a set of rollers to test locomotives.
You will need:
Standard 608 8x22x7 “skateboard” bearings
If you want to draw power from the track, a bit of 1/32” x 1/8” brass strip stock bent like an “L” can be pushed in as shown. Alternatively, a similar size strip of any conductive metal can be used. I've made some with repurposed box staples!

These can be used on their own but are more stable when set atop a length of track or press fit on 1/8” x 1” bar stock.
The “Sloppy” version uses 8.5mm pins to accommodate cheap skate bearings on eBay that have a larger inner diameter don’t fit snugly on the pins.
