Train Couplers and magnetic uncouplers

[Anonymous]

I've been collecting train cars for two years - mostly Kaddee and Proto 2000 units. This past year I've been buying brass units from Overland, Railroad Classics, etc. Problem is - most come without couplers. What does one do - I see Kaddee #5s and is there #58s in Model Railroad Magazine, but not sure what the process is to buy these items. Do I need special tools? And what's this magnetic uncoupler unit all about? I get the concept, but have not laid any track other than a club module. Is one better than another? I've seen electric uncouplers in the train shops. Anyone care to give me any advice?

The only advice I have for you, is post this question in the Model Railroading forum. Kadee couplers are the way to go, as far as I am concerned, but I am not familiar with brass locos.
Good luck, Todd C.
