Greg Houser posted:You could also just raise the outside main, remove the passing siding, and make this line's lift bridge the one that's elevated. You'd probably have to do a 4-5% grade to get up to 6" but it's certainly doable.

Yah, that could be cool! But I like the double-track mainlines look (though they could be a different elevations, perhaps 1/4" different). Anyway, they should be level through the bridge. The mountain would need to get taller and steeper to clear a line at up to 6". Maybe.
