Me again, Len. Your optimistic "nothing is impossible with a file & glue" got me thinking and looking. I have a Rivarossi 0-6-0 tank engine that runs like scalded cat, which is why I haven't used it. However, being an Italy manufactured loco, I checked it out. Although it had Kadees on it, the coupler pockets seemed to be designed for hook & loop also. For $3.85 I bought two replacement hook & loops. SUCCESS. The little loco coupled up and the consist ran great. Thanks for the "never give up" attitude.
