Upper left picture of what they call a road train vehicle. We saw an oil tanker that had 4 trailers on it. Are big enough they need extra wheels with 12 in front and 12 in the front. Upper right shows the all in one vehicle…road or rail. If the road is washed out you just take the railroad track. Lower left is a vehicle that some girls were using for their touring of middle Australia! And two brown Kangaroos that were at the camel track previously mentioned.
