Just so we’re on the same level here - your own article states that high speed rail as it is most commonly referred to means speeds of above at least 200km/h, more commonly beyond 250. Lower speeds are “higher speed rail” in America, or regional/local lines in Europe. My local lowest tier urban mass transit has a normal speed of 160km/h.
America has ONE Line with speeds beyond 250, and that is where all except one of its 200+ speeds lie aswell. That is, sorry, a joke. For one line a network does not make.
Look at that same graphic in the article on the high speed network in Europe and tell me they are even close to comparable.
My nearest lowest tier rail bound mass transit system is the S-Bahn Hannover which uses Stadler FLIRT XL 3 at a top speed of 160km/h, yet they only serve Hannover and its immediate surroundings.
This is also the case with the S-Bahn Bern (using Stadler KISS), parts of the S-Bahn Rhine-Ruhr, the S-Bahn Bremen, S-Bahn Mitteldeutschland (Leipzig Halle), S-Bahn Dresden, S-Bahn Zurich and Wiener Schnellbahnen.
If you live near a big(ger) city in the DACH Region but not directly in it (meaning out of range of its Tram system) this is absolutely not uncommon.
