how many pieces of auto reversing track do i need for a trolley run? and can imix it with standard ez track?
If you do a search on "auto reversing track " on the search icon , lot of good info . But no you can not use regular EZ Track , if you did you would have to run feeder wires from track to track . Bachmann sells the 9" straights and I believe 18"r reversing tracks
You can use Ez-track in the center between the reversing track, but as mf5117 mentioned you have to run feeders, but not to every piece of track, you just have to connect the end track conductors that are underneath.
