I love the look of these new Lionel Corporation Tinplate sets. However I noticed on a different thread that several people have had issues with the wheels slipping when pulling the passenger cars that go with these. The problem seems to be the "coupling shoe" on the bottom of each wheel set. This shoe is causing the cars to drag rather than freely rolling down the track.
Here is a cheap solution that works;
You need to purchase some small cable ties, the ones I bought were purchased from Dollar Tree.
Poke the tie behind the wheels and connect the ends. You must cross over the mechanical uncoupling device; the shoe.
Pull the tie tightly locking the shoe against the bottom of the wheel set. Cut off the slack at the end of the tie.
You will find that the car will pull with much, much, less resistance. This will also help if the shoe causes the coupler to open when crossing over some switches. With this fix I can easily pull the 4 car set with my 263E engine at 3 Scale Miles per Hour with zero slippage.
