Wire wheel for the tender wheels, not the track. I polished the track with a track polishing pad. Its nice and shiny! Its the tender wheels that are not the prettiest. This is the 1939 thru 1942 track. The 1938 version of the 3 rail has spring clips at the end of each section. The track has the open space under the road bed in the middle, but sitting on my carpet"grass", you cannot see that very well. AD
