Thank you for everyone's input!

I do and I reinstalled them . What would be the solution to this problem? I now have 20 metal wheels that are unused (Fortunately I was able to replace the plastic wheels on my non-Bachmann passenger car). I've read that plastic wheels are terrible on metal tracks and would like to have metal wheels on all my rolling stock.

First off, I am new to this forum and model railroading. I did a brief search of my question and didn't locate what I was looking for. However, if my question has already been answered in another thread, please let me know.

I just recently purchased the Chattanooga and wanted to put metal wheels on the rolling stock. When I did, the wheels did not roll as smoothly as the plastic ones did. They are Kadee 33" wheels, but somehow I missed something somewhere. Any advice will be extremely helpful.

Thanks, Scott
