Trains are one of the safest ways to travel, but it hasn't always been like that. In this talk I will introduce the basics of railway signalling, and look at how it has evolved over time - often in response to accidents and near-misses. You will find out how a single stray wire caused an accident that killed 35 people, why leaves on the line cause such a problem for the railways, and how signalling systems are designed to deal with the inevitable human error.
This talk sounds like it might only be of interest to railway enthusiasts, but I have done a lot of work to make it broadly accessible and of interest to "normal people". I have had very good feedback from giving this talk to local science groups, U3A groups and so on.

As well as giving talks, I currently work as a freelance geospatial software engineer, working with clients ranging from small community groups to multi-national corporations to store, process and visualise geographic data such as satellite images and maps.
I am happy to give talks online or in person, although for in-person talks you should be aware that I use a wheelchair.
I am based in Southampton, but willing to travel reasonable distances to give talks - always feel free to ask even if you're a bit further away, the worst I can say is no!
