Stewart, the above is great and super helpful. About to start wiring up my #6924's to my #57's.
QUESTION #1) Is the below diagram from Steve still OK to use if you have, ie., smaller switch's, 0-36 to 0-54, where trains cruise through fine. Another way to put it is......does the BLUE / YELLOW Power Routing rails really need to be wired back to #6924 if trains go through switch without stalling, OR does the power routing wires actually active the Non-Derail feature?
QUESTION #2) Looks like CT Mike has 3 Amp fuses on his #6924's. Necessary or just extra insurance? If really needed not sure how those are wired.
QUESTION #3: J 6 COM & POWER: 6-22VAC/DC. Does this go back to Accessory Post on my KW OR....... is this the link/daisy chain to next #6924?
Thanks! Mark
