Make sure your fleet is running smootly with these handy ball-bearing rollers. E-Z Riders allow you to run your loco in place on your workbench or in a display case. Simply place them on a powered piece of track and place one under each of your locos powered axles. Non-rolling (fixed) versions are also available to support unpowered axles. E-Z Riders work for HO and On30 locos.
