Well, you specifically mentioned trains in Germany. I&#x27;ve ridden quite a few, and I can tell you, they almost never go that fast, and not for long periods of time. With all the stop and go, all the slow tracks, quiet areas, and whatever else, the average speed isn&#x27;t that high. So in general the US should probably not focus on superfast trains, since they don&#x27;t pan out usually, but just getting some decent trains that are on-time and reasonably fast.
