Wuppertal Monorail

The Wuppertal monorail system is almost 110 years old and still operational. I'll admit I was quite surprised when I read the article but it is a reminder that there are very few original ideas around. The monorail survived World War II and has an impressive safety record with only incident in 1999 resulting in fatalities. There was another, much less tragic, incident in 1950 involving a pachyderm.
