During some beta testing of a repaint of the default F7 I have come across an issue with the F7 front and rear couplers. If the F7 is used as a stand alone unit without the B it will not rear couple to any rolling stock...ie, hoppers, box cars...etc, even the default ACF chaircar. The front coupler of the F7 will couple at all, even with a B unit hitched up. I presume this is an issue from the default release that has never been looked at or fixed and was wondering if a 3rd party fix was ever released if this was the case. I have tried to modify the BIN file with no results and am at a loss as to why?
I have done all the delete pak, etc and verify's and searched forums.....has anybody else come across this issue?.
Thanks in advance.

as does Dick Cowens E7.....
..will have to dig deeper.
