I made the mistake of making mine less than 30″ and eventually had to tear the whole thing plus over eight feet of track to accomidate the longer cars, the 6 axle monsters I use on the mine runs and several 60 foot freight cars and 75 foot passenger cars. It was one heckuva Ooops-Oh to correct. If you’re going to include tunnels do your best to plan for placing them in areas where the main or even a branch line is decently straight. ###

I have just recently puchased a set of 5 Gunderson well deck wagons, but can only carry one container high, until I raise the height of all eleven tunnels. (mutter, mutter, mutter)
