Babbage invented loads of things but were any of them built during his lifetime?I was going to mention our own shared roads in the Manchester area but the Metrolink trams are babies, compared to the monster in the picture!
Instead, here's a page about Cow-catchers, Pilots and Anti-climbers!
"The pilot was invented by Charles Babbage in the 19th century, during his period of working for the Liverpool and Manchester Railway. However, Babbage's invention was not constructed, and it is uncertain whether later manufacturers were aware of Babbage's idea."
Yes, that Charles Babbage!
