There isn't an Atlas shortage ANYMORE. They have in the past, just like MTH & Lionel, sometimes run out.
Gargraves is least likely to have a shortage IMO, since track is all they do.
The last real shortage I recall was in the 70s with a supplier shake up, they came up short on switches. Ross lost the same source I think; but they couldn't complete it either, but didn't have enough regular track...We mixed Lionel, GG, Ross , and I think Atlas (or Athern?) for a couple months; GG came thru first.
Nobody liked the green-blonde Ross ties next to other track; they didn't outshine the others THAT much. Eventually the kids melted the other turnout motord by parking on the anti-derail trigger rails, so Lionel turnouts went back to controlling the more accident prone splits.
