Required two pairs of coupler for two wagons that I had just bought. There are a large number of options in the Kadee range. My two wagons had a mounting platform at the end of the bodyshell and so I decided on the #158 version. As these do not have any fixing screws, I just glued them in place. They provide a nice coupling distance between the two wagons and my locomotive. Think I may now need to covert some of my other rolling stock with Kadee couplings. They just look much better than other couplers used on European rolling stock.
