Thou shalt never, ever, ever complain that Deutsche Bahn's online tools are bad until you have tried making Renfe's website do anything at all. It's such a pile of complete and total abject shit. In comparison Deutsche Bahn's digital services are like some wonderful Neuland.
@jon True... the DB website has all the flaws of modern online services... but it works and has information that is correct. Also I always thought their app DB Navigator was pretty good
@Konzertheld Exactly. The basics work if you know how to make it work for you.
