Alan...HOLY COW...140 poles!! If you end up not using all of them, please let me know..I may be interested in some!
OK...the total run distance on this part of the layout is just under 45 feet. A few adjustments had to be done to get everything to work out. The poles for the most part are 20" apart since that is the length of the MTH catenary wire. Of course where one would have to cut or make other adjustments then the number of poles and lengths of wires would vary...hope this helps.
