Im currently in the process of purchasing a scale wheel MTH engine (22-21307-2) has one I was told it would be ok on my O-54 curves with the hi-rail wheel set and two I like the idea of the fixed pilots but so far all im able to find out is that I will only be able to use kadee couplers the problem being all of my rolling stock use the standard o gauge couplers and with O-54 curves I don't want to convert them to kaydees untill I can upgrade to O-72 and lathers curves. So my question is is there a santander o gauge coupler untill I get larger curves or would it be better to remove one of the proto-couplers from my other gp38-2 untill I can go full kadee?
