Are there documents covering lubrication for 2-6-0 Mogul (P/N 81497), and 4-6-0 Anniversary (P/N 91604)?  It's covered in VHS tapes provided w/ the products, but these are not particularly convenient...  The .pdf documents on Bachmann website in Product Reference don't cover lubrication / maintenance...

Can somebody please advise if docs exist covering the lubrication?

If not, Bachmann please produce some at earliest convenience.  Thanks.
