In the newly created Crossover Module photo album on this group, I have place 2 photos (one overhead and one side) of the 6 foot crossover module that I created a couple of years ago and that we use for the DC ZBend Track group. It has been used at a couple of shows, and can support trains of 50 or 60 cars. Brian, Rob, Randy et al, please correct me if I am off on the numbers. To compensate for the crossover, a specially wired balloon end module is used next to the crossover. One pair of tracks dips down and one rises up, for perhaps a 2+ per cent grade. For the first show, a non-balloon end module was used, but it severely limited the train lengths because a too tight radius was used. The balloon end module, with a much wider radius, appears to have alleviated this issue. For the balloon end module, the track feeder wires that normally go to the outside rail outer track are wired to the connector post for the inside rail inner track, etc.
