My rules for train travel are:

- take the train in front of you that goes towards your destination. A hypothetical later train that might be “better” for whatever reason will let you down.

- do not trust any info more than any other. DB Navigator will lie to you, station screens will lie to you, DB lounge real-time screens will lie to you, staff and fellow travellers will give you outdated information, screens *on the train* sometimes lie to you. You can only trust your instinct while correlating all of the above.

- take it easy and don’t stress out other travellers or staff. It is what it is (with apologies to the guy who needs to be at BER soon who went after one member of staff in frustration).

- taking out a speculative reservation on a subsequent train can be a life-saver.

- charge your electronic devices when you can. Discharge your biological devices when you can.

- grab a snack & drink when you can.
