I am now in #Berlin waiting for my night train. The train from Warsaw was a bit late as we spent some time in Rzepin waiting for a new locomotive.Of course I met a FOSDEM attendee on the train, a Debian person.CO2 levels were high at the beginning but quickly decreased as the train moved, thanks to generous drafts from the corridors (as long as you kept the compartment door open). The restaurant wagon was well ventilated (but also almost empty).#EC44
