I have been looking for the following items and as strange as it seems, these popular road names, features, and configurations do not seem to exist:
1) Lionel UP FA, Alco AA set, or F3 in Legacy...seems they are only in conventional, except for the lone very expensive TMCC Anniversary set ($1300)
2) MTH UP FA, Alco AA set, or F3 in Rail King PS2/3 variant and/or with smoke (ex. there is a $459 RK engine set with no smoke)
3) Lionel Santa Fe Yellow and Red warbonnet with Legacy
