Technology
ATS systems can be mechanical, where an arm is raised on the track to engage a lever on the train to apply the brakes and cut the power. The mechanical systems around the world are generally incompatible. Mechanical systems are not suitable at high speeds, say greater than 110 km/h.
ATS systems can also be non-contact magnetic or inductive. Again they tend to be incompatible. Non contact systems are suitable for high speeds.

Famous quotes containing the word technology:
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
