In 1866, a year in which 1,102 people were killed and 1,334 injured on roads in London, John proposed a signaling system based on railway signals. John became superintendent of the South Eastern Railway at age 25 and then traffic manager of the Brighton line by age 40.
He also specialised in designing signalling systems for Britains growing railroad network. (Which he saw no reason why they couldn't be used on the road.)
