It's Christman again and once again I am setting up my train for the grandchildren and once again, with new Bachmann equipment and a question.  Last year I was very happy with my new easytrack system once you posters helped me with a swith problem.

This year it is an unexpected problem with the couplers on a new Bachmann (I bought Bachmann since I was so happy with the track) engine which, to my surprise, is incompatable with my 30+ year old rolling stock (Tyco and AHM with horn hook (?) couplers).

I would like to change the couplers on the engine (have schematic, screw visible, etc.) rather than on a dozen or so cars.  Can you recommend the correct horn hook couplers which will be compatable with my rolling stock and work on the new Bachmann engine.  Thanks for your help.  I along with my grandchildren are very appreciative.
