Ace,
Great job on the diagram! Thanks for that. Switches 7 & 8 are manual so don't really come into it(no non-derailing function). The only thing to remember is to reset the path after your engine leaves the siding- beware of derailments. One comment I would like to add is that although Lionel (on http://lionelllc.wordpress.com/projects-and-tips/) mentions that the switches operate best at 14 volts, I find that my cw-80 transformer snaps them pretty good at the default transformer setting of 10-11 volts. The thing about my layout, at least now, is that the only ACC constant draw is the blinking Coke tower, the barrel house light and the gateman light. Possibly if I add some street lamps later, after I add some roads I might need to bump the voltage to achieve the needed current for the lamps. Apparently the switches only use voltage since there are no lamps in them, so for now I should be OK.
Thanks to you too Walt for your information on the capacitor solution.
Regards,
Eric.
