Nothing quite new, the DB is as unreliable as it can get. How will they ever be able to compete with cars or airplanes if they don't even manage to bring you from Graz to Erlangen in less than 8h? By car it's usually between four and five hours, by plane less than 2.5h.
Not to mention I had booked a seat (air conditioned, first class, power plug, etc.) and I got no power plug, something over 40°C in the cabin (it was the hottest day of the year 2009) and 3h delay.
The last time I chose the DB for transportation service this year.
