An engineer’s dream and feat made true. “Why don’t we broadcast a real time video of the train moving in the landscape, seen from a drone, synchronized with the movement of the train in the landscape?” So that when you travel in Switzerland, you vicariously enjoy the sunny landscape around you, which may be especially rewarding in case of bad weather. The next step, of course, is getting rid of those expensive, hard to maintain windows. The step after the next is the abolition of travel tout court.
