paliden45 - The following is being provided because when I tried opening the link that Ed B cited it said there was an error. Consequently you can find virtually any Lionel Owner's Manual by doing the following...
- Call up Lionel.Support
- on left hand side select 'Resources' and scroll down to Owner's Manuals
- scroll down the page that opens and fill in the item number (6-18043) in the 'Product Name or Number' space provided, then click on 'Search'
- it will open to the Pictorial Diagram or Manual for your engine
Good Luck!
