Thank you for making me feel much less safe on Swiss trains now =)
That aside, I've often been wondering how these systems work exactly. There must be a challenging engineering problem behind organizing all of this.
- Turing_Machine 10y agoYes, it's fascinating. For a look at how a complex system this can be handled without computers, do some reading on how signaling and train movements were handled in the 19th Century. Pretty amazing how they were able to control continent-wide rail systems with hundreds of trains in motion at any given time, using just a telegraph wire, manual signal lanterns, slips of paper, etc... without (usually) causing any collisions.
