Help I'm Changing couplers ??? and need them explained I have two questions here that I need a little help with I know it may have been explained somewhere here before, I have done a search for the first question and came up with nothing that will help, alot of the links dont seem to work as the threads are quite old. 1) I have some old Hornby rolling stock and loco's and I want to change the couplers to Kadee. Is there any kits available or am I going to have to fabricate something up. 2) I want to use the above mentioned locos as shunters in my yard and I am unsure how the auto uncouplers work. I am looking at having 6 - 10 sidings to work out of and I need to know if I can set the uncouplers up to be used via a DCC type controller. I would like to have the railroad controlled by a PC using PLC type control incorporating the DCC.
