Yamix1:160 N Scale Model Train Accessories Treadmill Track Test Stand Test Track Bearing with Connecting Line for N Scale Model

This is a nice test stand. You may have to buy more roller pairs if you want to run large steam locomotives on it. Many steam locomotives require the tender to be powered.The hard part of using this is getting all the wheels in the right place. N scale locomotives are hard enough to put on normal track. This is harder. But it is worth it.

Item arrived ahead of schedule. It was very well wrapped for the trip from China. There are no issues with quality. Preliminary testing proved that the product performed as expected. Inserted banana plugs into the ends of each tube for locomotive power. DC and DCC performance was good. The roller bearing trolleys slid easily to adjust for truck configurations while maintaining good electrical contact.

i disliked that no instruction came with it to show how to use it!

Solidly made and precision assembled, meets the proper gauge for N-scale locomotives. The rollers are easy to move to the appropriate spacing and stay in place when set. If you're testing locomotives with more than six axles, there's an add-on set of rollers available. My only wish would be for them to add a set of contacts on one of the ends to make it easier to attach power leads, but alligator clips work alright.
