You can actually cheat a little bit. Don't think of one track going up or down. Where my train departs for an upper level, I have that track going up and the other track going down at the same time. That way the run to get the required height is not as great. One track goes up 4 inches and one track goes down 4 inches, now I have 8 inches of clearance for the train to go to a tunnel below the upper level.
This run is 21 feet to go from level to an 8" clearance. But that is really only 4 inches over a 21 foot run. Pardon the mess, I've been working on this area.
Have Fun, Ron
Nice solution. Love those houses!
