Gradients
I stretched a track across my 45 mile long route, and then made the gradient as steep as the maximum possible in Trainz...and drove a "Jet Sled" in Cab view up the gradient, (also laid a negative gradient to see how low trains can go, viewing what is underneath baseboards), and the route slowly got smaller and smaller, finally disappeared at several miles high. Anyone ever lay invisible track at 1000' above a route, and fly planes or trains on the elevated track ? Cool sky view from a Jet Sled as it has no windshield obstructions in Cab view. Also with 20 Jet Sleds I pulled a 1000+ car coal train...cars flying went EVERYWHERE on the Tehachapi Route at 785 mph. I layed invisble track in the air at all different levels and made airplanes divebomb and assend, ducking under bridges and powerlines, like a barnstormer. Also had 20 airplanes in flight, and viewed them in free mode, zooming by in sucession on a never ending loop of aerial track 45 miles long. Built an impossibly large airport by laying and rotating 10 airports together in a collage, and viewing takeoffs and landings in free mode. Put portals at opposite ends of a 45 mile long route and set them to accept and generate trains over and over again, every 5 min, with dozens of trains at syncronized speeds, running over the Horseshoe Curve to Johnstown route in a never ending parade of traffic, and view them in free mode. On the Moon and Mars route, made a ski jump of monorail track, and a huge towering volcano of moten lava, with dozens of smoke emiters sunk into the crater for massive smoke effect, and launched trains into it from a mile away...things you do when you get bored !
