Bad news for everyone travelling to #SAPtd in Berlin by train: it seems there will be a strike of german railway workers that may last until monday:

This will surely affect other methods of getting to Berlin, so please plan accordingly.
Given that the Berlin S-Bahn will likely be on strike as well, maybe it's a good idea to share Taxis? Maybe some of us can arrange a meeting point to get to our respective hotels. If you're interested add your dates in the comments, please.
I'll be arriving 10:35 in Berlin Tegel (TXL) driving to the NH Hotel Kurfürstendamm. Happy to wait for an hour or so.
