Jan,
Makes sense to have both crossovers on either side of the Wye. I also cleaned up all the joints so a simulation can be run. It bumped the number of cut tracks to 8, but if Bob follows my advice to replace all the smaller fitters with larger cut pieces, it shouldn't be too bad. I don't know what he has planned for landscaping, but I went ahead and added the extra whisker tracks. Now it's up to him to let us know what he likes and doesn't like, especially the 3-stall roundhouse.
