Well we are just trying to point out simple facts from our own experience with these engines. Is this your first 3rd Rail steam engine?
This is NOT HO scale.
Lionel Fastrack is NOT Kato track
Whatever you have done in the past with HO doesn't mean the same is true in this case. Did you ever try to run your Hallmark brass at a scale 100mph on a 15" radius curve of Bachman EZ Track??? I highly doubt it.
