I am starting to regret building my layout with code 83 track. Most Rrivarossi steam will not run right unless I file down the flanges , the same for a lot of Mehano /IHC steam. Later Bachmann is fine and Mantua are ok except for some lead trucks. Older cars are the same Rivarossi passenger cars are a no go. Maybe should have just went with code 100. However code 83 does look nice. Just venting after my latest build did the flange clicking on my first test run.
