Russ....Aug. 23/24 2022

So there's a note with an exclamation point in red that "hohe Auslastung" (high demand) is expected for pretty much all departures and that bike transport or even standing space cannot be guaranteed. Guessing here... perhaps they're expecting a shortage of train equipment? Or perhaps there's just been so much free-wheeling use of the 9-euro ticket that the trains have gotten super-full and DB feels obliged to issue this notice? The notice does seem to be absent from Sept. 1 onward (when the 9-euro month-long ticket offer dies a quick death.)

Is that a time for festivals on the Rhine? Fireworks or wine festivals?

Not so much, Stan. Bacharach holds a culinary/wine evening on the 28th, but the more popular wine fests (with fireworks, wine/food stands, big crowds) take place on weekends in September and the first week of October. Gary's August dates are weekdays.

It looks to be specific to a single route - RB26, which is the only one that stops in St Goar. The other lines that run through Bacharach don't carry that warning. Could be something happening outside the area you're visiting. Rhine on fire isn't happening that week (or anything else out of the ordinary).

I guess it all makes sense. Thank you, Russ. I appreciate your insights.

Or perhaps there's just been so much free-wheeling use of the 9-euro ticket that the trains have gotten super-full and DB feels obliged to issue this notice?

This. But I wouldn't attach too much importance to that. Unlike long-distance trains, where the DB can make somewhat precise prognoses based on reservations and tickets issued with fixed destinations, this is impossible for local trains. There most tickets, like the 9€ ticket, are a kind of pass without a fixed destination, and reservations do not exist. So the forecasts of occupancy are simply based on estimates. And these get linked to the train numbers. As a consequence, it can easily happen that the prognosis is true only for a part of the train route and the DB app still issues a warning for the other segments of the route too.

For example, I travel once a week on a train originating in Munich (terminus is Nürnberg), which is always fully occupied by commuters as far as Ingolstadt. From there to Treuchtlingen, however, it is yawningly empty and only then fills up again with travellers originating in Augsburg. And yet an overload warning appears in the app for for the Ingolstadt-Treuchtlingen leg too.

BTW, the binding of the warning to the train number often has other baffling, albeit funny
consequences. This is the warning for the train mentioned above:

RB 59102: Eichstätt Bahnhof->Treuchtlingen: Störung. Bitte nutzen Sie aufgrund
der hohen Auslastung der Regionalzüge auch die S-Bahnen der Linie S 2 zur Fahrt
nach Dachau Bahnhof und Petershausen.
RB 59102: Eichstätt Bahnhof->Treuchtlingen: Information. Aufgrund der hohen
Auslastung auf der Linie RE 1 und RB 16, empfehlen wir Ihnen als
Reisealternative nach Nürnberg die RE 8 und RE 16 über Augsburg und
Treuchtlingen nach Nürnberg.

Well, Dachau and Petershausen are approx. 70km south of the starting point of my north-bound journey. And likewise pointless for me is the suggestion to take a train from Munich via Augsburg to Treuchtlingen (direction south-north) while I'm travelling from Treuchtlingen to Augsburg (direction north-south).

thank you for clarifying the train issue. I will proceed with my itinerary with that in mind.
