If you think DBS is bad, have a look at what DB did to the Berlin S- Bahn, the latest is that it may be up to three years until services are back to normal, extending service times until wheel sets give and then being forced to withdraw trains to replace the wheel sets. At last two managers have gone but that don't help the suffering passengers who don't know from one day to the next at what frequency the trains are going to run!
