you might laugh at the video in OP, but it took me a while to find out that you pull the table towards you in the ICE 4 trains.
In other news, if you want to buy your own ICE, DB is selling their BR406 train sets. a couple of them still have the logo of the Nederlandse Spoorwegen on them, even after they sold them to DB. I just saw one in Frankfurt today on its way to the Ruhrpott joined with a normal ICE 3 BR403. I like the OG black info screens that they still have.
