For an honest comparison the US picture should be an Acela,or at the least abn electric hauled northeast corridor train. Some of these pictures appear to have been photoshopped to remove the overhead electrification.
Gather up pictures of freight trains and the answer would be quite the opposite. Likewise, if you compere the pictures of the ordinary passenger trains in these countries with those in the US the wonders you get by looking only at the top of the top in each country do nto exist.
Passenger equipment does not equal infrastructure in total. The freight trains that we run at 70 mph on our supposedly antique infrastructure would completely destory the infrastructure that is supporting these beauteous trains.
