Hi Folks, I wanted to make a few more comments about Atlas track and traction tires. Atlas track has a T shaped top that is closer to real railroad track than other brands. The inside of the top is almost vertical whereas the inside of other brands is more rounded. In my experience, the Atlas track cuts the traction tires. The tires don't wear out. They are cut.
This has happened on most of my engines but not all of them. I have a few engines that I have run for years without losing a traction tire. The vast majority of my engines have lost at least one traction tire after a few laps, however.
Of course, this may be just a problem with the way I lay track. I am pretty careful to make sure all the track and joints are smooth.
Most of my friends use Gargarves or other track brands. They do not seem to have this problem. Their track work doesn't appear to be any better or worse than my track work.
In any case, it doesn't matter if an engine is MTH, Lionel, Atlas or other, over 90% loose at least one traction tire after a few laps on my Atlas track.
I initially choose Atlas track because I believe that looks closer to prototype track than other brands. The ties are smaller and closer together, etc. Another major consideration is that the local trains stores carry Atlas. None of them carry Gargraves, Scaletrax, etc.
I choose Atlas for the garden G&O railroad because the ties are UV rated and the solid rails stay in place when you step on it. So far it has stood up well in the sun and rain. It doesn't freeze or snow in the SF Bay Area - at least not very often.
