Coupler replacement time

This task has been on the list for a long time.  Most of these locomotives lined up are from Kato and have Kato couplers.  My preference for couplers has always been Micro-trains.  So, in between building the Conoco Plant for the Sn3 layout, and awaiting glue to dry, I am going to start replacing the couplers on these ten modern locomotives. Not exciting for sure, but operation will be better.
