Question for those who have/use rails in their display cases. For 3-rail engines, do you display them on 3-rail track? Does anybody use 2 rail track?
It probably doesn't make much difference, I'm just wondering if sitting a 3-rail engine on 3-rail track for years at a time might scrunch up the springs in the electric pick-up rollers and whether it might be better for long times to let a 3-rail engine sit on 2-rail track (which obviously would look more natural to all my non-train friends who would look at the display). Anybody think there's a strong reason to go one or the other - or better yet, have experience?
