If referring to my earlier post, here are some replies to amtrak's questions. No, the figures in the animated accessories from Lionel (skaters) and Lemax (snow angel) are not interchangeable. For snow I use Woodland's Scenic Soft Flake Snow, then Extra Fine Buffalo Flurries (be sure it's Extra Fine), then sprinkle some Diamond Dust for a bit of sparkle (see photo for products).
Hope this helps.
