Our experience was mostly smooth. Landed remote of course, stopped by the Welcome Lounge for some nibbles and to freshen up, then headed to the rail terminal. Bags arrived there right with us, picked them up (they are organized by your destination, so hard to miss), and then headed for the DB Lounge. We were denied access, and there was no argument brooked. The lady at the front told us that not all first class train tickets get lounge access and ours didn't have it. Slightly annoying - I'd have stayed in the Welcome Lounge longer. We hung out in the Hilton lobby instead until it was train time!
