I don’t have one but I know that you will certainly need to worry about larger flange wheels. Most older n scale wheels bump the spike detail on Atlas code 55 track!

I model my railroad and you model yours! I model my way and you model yours!
Not sure about N, but my HO tank car has no problems.
Have fun,

Anybody using one of these track cleaning cars on Atlas n scalecode 55 track?
Does it pass over turnouts and grade crossing OK?
