I would really like to see some basic Frisco livery Heavyweight passenger cars; Baggage, RPO, Coach, Business Cars.
I would really like to see Business Cars; St.Louis; SanFranciso, modified prior to their retirement. In HO scale and or 2 rail O scale.
Random cars I guess. Its mostly wishful thinking, but if Walthers were to make a run of the Texas Special, that would be a whole set of cars ready to go without need for renumbering/renaming
