One of the biggest problems a model railroader can have is couplers that cause a car to derail or not couple correctly. Where you use the Kadee or McHenry couplers here is a very inexpensive tool you should not be without. A coupler test track.

The set up is easy. Take the roadbed as is, you don’t need to split it. Just lay down the roadbed with white glue. You will want to trim the edges. While the glue is setting up, about 2/3 of the way down cut out a section of roadbed for the uncoupler magnet and the metal plate down.
