Austrian rail wanted a higher speed line through most of the country. Iirc the plan was to extend it to Zürich-Budapest eventually. Only problem was a few dozen km of the line goes through Germany and they didn’t want the higher speed tracks installed. Like, Austrian rail was going to pay for them. They just didn’t want noise. It’s unfortunately a big enough portion of the line that it made it not worthwhile.
