Forgive me for my ignorance, but wouldn't adding a few balises to the track (https://en.wikipedia.org/wiki/Balise https://en.wikipedia.org/wiki/Balise), and the matching receiver in the trains, be enough to limit the train speed to what the track allows? Or would even a simple system with fixed balises need FCC approval?

- gsnedders 11y agoThe political will has always seemed to be to go for a better solution than a few balises, probably in part given there is so much fight to get anything that installing some balises would likely hold back introducing anything better in the near future.
