My search for the perfect controller continues. I have two Rokuhan controllers and two hand held Snail Speed controllers. I do not have any Marklin controllers due to their relatively high cost. I have decided that the Rokuhan controllers, while being very nice to handle, do not work at all well with the newer Marklin locos with new generation bell shaped armature motors. The Rokuhan constant lighting system means that these super efficient locos can only stop and start abruptly or run at fairly high speeds. I like the Snail Speed controllers in operation but they are small and finicky to handle, better suited to mounting on a board, a different design than the ones I purchased. So I am considering trying the Marklin controller. It appears to have a nice big throttle and no switches to flip or buttons to push. I now have Marklin 5 pole and new generation locos, a Rokuhan loco, and a pair of AZL locos. Can someone tell me if the Marklin controller works well with all of these?
