Works really good, thanks for asking!DisneyMom wrote:Wow, could we have used MAPO in Chatsworth to avoid that horrible crash?
How does it work?
But in case you're serious, it's a Positive Train Control system that uses coded signals on the propulsion rails to limit train speed (sometimes to zero) to prevent overspeeds and collisions.
And yes, that is *exactly* the sort of system some have been calling for on passenger rail lines like the one in Chatsworth. Resistance to the program comes from the fact that it requires not only installation on every mile of track, but on each and every locomotive in the country that could ever operate over a passenger line. Not cheap, but some think it cheaper than the wrecks it would certainly prevent.
