I have a new Lionchief Plus Hudson. It has a squeak. The squeak is in the locomotive and not the tender. It's not constant more like every 5 seconds when going around an O48 circle at low speed. I've lightly oiled front and rear truck wheels and all the points where any rod and gear linkage joins or slides. I didn't touch where the trucks swivel as there is plenty of grease there. It seamed like an easy fix but I'm stumped.
