I fabricated this monstrosity with dig holes and various spline content as slabs, platforms and walls. There is no ready-made tunnel/portal content for a two-track system on a standard-gauge American road. My flat tunnel ceiling is tall enough to clear tri-level autoracks and double-stack well cars by at least a foot. The track goes from curve to straight right at the mouth of this particular tunnel. Whether track curvature is permitted to abruptly change on actual American roads right at the tunnel entrance, I'm not certain, but on turns, there is at least two feet of clearance between overhanging trains and the tunnel walls. I'm not certain what the American loading gauge calls for regarding tunnel overhead clearance or side wall clearances. This portal was built oversize to completely conceal any dighole space. The polygonal nature of Trainz graphics precludes neat rounded structures in many cases.
