The little plastic connector that hooks on the tender pin is broken. I have been unable to make any kind of wire wrapped around little post on tender stay in place. What to do?
Which engine is it? I assume you mean On30? Check parts diagram and see if there is a part you can order from Bachmann service (assuming this is a Bachmann engine.)
I think you are looking for a draw bar. You can buy them out of the Walther's catalog. You can make one yourself. In HO I've heard people use an expired credit card as the raw material.
