Beyond the cursory lubrication points pictured in the owners manual for the "Hogwarts"-type 4-6-0 locomotive & its varied versions (Santa's Flyer, Halloween, & Shakespere), is there anything internally that should be lubed every several years?
Its hard to believe there is not a major internal drive gear or two that would requiring some occasional attention.
Also, what about the same for the Berkshire locos found in Lionel's Polar Express, Major League Baseball and similar sets? Thank you!
