Ever try rollers…?
…they work well, and don’t take up space…
You should also always have a short piece of track, and one or two coupler gauges. Checking wheel gauge should be done with a Back-Back wheel gauge or caliper, not the piece of track that you use for testing.
Although running on a piece of track does prove that the equipment will run. Most “Testing” can be done on the bench, if you know what needs to be checked, and how to do the checking.
Too many people today seem to just take things out of the box, then on to the track, without checking certain things; then wonder why they have derailments.
Yes of course, you have to apply the same consideration to the whole rail system, with good substantial roadbed, and properly layed track.
No-mater how much checking is done on the bench, or on a test track; the track structure has to meet certain standards also, for “Frustration-free” operation. This includes everything, including switches. You can buy or hand lay the best of track and switches, but without a good substantial roadbed, you will eventually have frustrations…
