As an Austrian, I must say that I am amazed that this is even a topic here ... let alone a topic that gathers so many comments. I thoroughly appreciate all the comments and insights.
Personally, my only complaint I ever had about the ÖBB was that they got rid of the repeating noise trains used to make. A noise they used to advertise with in the past.
It's called "Continuous Welded Rail". More expensive in initial installation, but way cheaper in maintenance and as a bonus it has better ride performance too.
