See here. http://www.dw.de/initial-gdl-strike-targets-deutsche-bahn-freight/a-17892092 So according to the union it will not really affect passengers mainly freight. But as booked they are the talking out of their proverbial. Just had a look at Hamburg live departure screen and it shows delays of 200 minutes plus. Same at Frankfurt. And all over Germany I suspect. Cheers then GDL. NOT. As booked and typical.
