Is there a metal coupler that fits the Bachmann Silver Series Freight Cars? Kadee #5 or #148 seem a bit too thick, and require replacing (or filing) the gear box.
Results may vary I suppose, but it has been my experience that the Kadee whisker spring couplers (148 or 158) fit in all Bachmann coupler boxes. That being said, on one occasion I recall using a flat needle file and brushed just a few gentle strokes down the middle of the coupler box lid. That created enough room for the metal coupler to freely swing.
Another choice: it is possible to file and burnish the Kadee coupler shank itself. Doesn't take much.
Regards,

It has been my experience that burnishing all Kadee couplers before installation helps avoid a lot of problems. A squirt of Kadee Grease'm or other graphite lube will also help with those sticky couplers.

A quick dressing with a fine file will take care
of any flash which might impede operation.
