This is version 3 (with updated textures and an extra invisible track in the water)
of the Tocumwal Bridge over the Murray River linking Victoria and New South Wales in Australia. This version is
interactive to open the bridge and stop automotive traffic at the approach of a boat that has been setup as a
locomotive riding on the invisible tracks in the water.
The blue invisible tracks are at ground level (z axis = 0 ft 0.0 in).
The red invisible track is at -3 meters (-9 ft 10.0 in).
The green invisible tracks are at -10 meters (-32 ft 9.0 in).
Many thanks to Craig Carr and Noel Brettoner for the many pics and info.
NOTE!!! It is possible to set this up in Surveyor to also control rail traffic across the bridge. See the README file
in the folder for instructions.
