Still testing passenger trains.
Had to replace the plastic couplers with Kadee couplers on a few cars as the coupler shanks are bending and allowing the cars to uncouple. Had a few spots where a couple cars would derail. The bolster has a plastic shaft that goes into the truck hole with a screw to secure it. Had to enlarge the truck hole to give more lateral and vertical movement. There's a couple spots on the layout where the roadbed changes from flat ply/homosote to laminated homosote and there is a slight 'bump' which I'm going to try to fix. Not easy as they are located in difficult locations but I have my 'topside creeper' to gain access to them.
