I have just recently built a few Parkside Dundas and Slaters wagon kits. Quite pleased with them, however as I am new to O Scale, I am not sure about what couplings to use. I have already attached the springed chain couplings supplied with the kit, but just trying to find out what type of couplings are out there that will make it a little less tedious to unhook/hook on other wagons. Also if anyone can offer any advice on building C&L turnout kits/ points I would be glad to hear from as the C&L website lacks photos.
