Well folks, I feel like I'm on a slippery slope here. I've been operating a mostly switching pike using a Lionel PWC NW2 for motive power. Then I went and bought an MTH SW1500.....and I'm instantly hooked on DCS with speed control. The trouble is that with slow speed switching moves there isn't sufficient impact to cause the lobster-claws to latch, which brings me then to Kadees. The problem is that I have 2 hidden O36 curves and I don't know whether body-mounted Kadees will negotiate curves that tight? If not has anyone had success mounting Kadees on MTH trucks? If so do Kadees align OK using 3-rail fast-angle wheelsets or is there frequent failure to couple?
