Loco Tender connection broken. How to fix ideas needed. ON3

[Chessieman]

 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.
