Japan also has some great non-suspended monorails. For example the one in Kitakyushu (I love the station architecture) or the one in Naha, Okinawa.
Also, there is a Simulator for Windows, OS X and the Wii U: https://de.wikipedia.org/wiki/Schwebebahn-Simulator_2013
The system was amazing for its time and its safety per passenger-distance is quite good for rail.
It was full of schoolchildren heading home at a leisurely pace, suspended over the river.
I had forgotten that you have to disembark at the end station so that the cars can be manually pushed onto outbound rail. I got some puzzled looks when I didn't de-train right away.
Also it's on Netflix in the US.

However, there just aren't a whole lot of advantages of having a suspended monorail instead of a "regular" straddle monorail. The infrastructure needed is much heavier and bulkier, plus the trains sway rather unpleasantly when turning and if it's windy.
