Bachmann HO/On30 42901 E-Z Riders with Ball Bearing Rollers

These are a nice item to have for testing Engines

Havent used them yet but eager to do so.

Perfect tool for my work bench allows me to free up space and still test locomotives preforming without long testing track.

These stationary rollers are good for stationary running, testing, and breaking-in HO locomotives. A little pricey but worth the convenience. MTS has great customer service.

These rollers are great for working on your locomotives and testing them stationary. They really come in handy when you are trying to program the chuff rate on a steam locomotive. You can set the steam locomotive on the tracks, start moving the wheels, then tweak the chuff rate so that its prototypical without the trains physically moving.
