Where I live the airport bus plays a prerecorded message. It's pretty obnoxious.

It's still an expectation I have, even as a native German speaker. I work for a well-known German company (our storefronts are sometimes called "the German embassy"), and our day-to-day business language at work is ... English. We hire from all over and want people to be able to get around effectively. This is infrastructure. Make it work.

Шановні пасажири, цей потяг який слідує від станції Івано-Франківськ Головний через Житомир до станції Київ-Дарниця буде розділено дві частини, вагони з першого по п'ятнадцятий прослідують до станції Київ-Головний, а вагони з шістнадцятого по двадцять перший поїдуть у пекло, муахаха. Дякую за вашу увагу.

Nu sunt englez, așa cã n-o sã-ți rãspund în englezã.

Honestly, it should be an obligation. DB should make it one for themselves. DB carries millions of people a year that do not speak the language. Important information like route changes should be available to them. English just happens to be the most likely language to be understood at least enough to ask staff/other passengers as to what is going on.

Not being under any obligation doesn't mean it is not a sensible a courteous way to do. You like it or not, english has become a defacto common international language.

While I speak 5 languages and try to learn some basic words of the local languages of any country I visit out of courtesy (how to say hello, bye, thank you, ask where are the toilets, etc), I wouldn't expect any traveller to know enough to understand this kind of specificities in any country they visit.

Of course they’re under no obligation to do so. In fact, they’re under no obligation to let in foreign tourists at all, or to not make their lives arbitrarily hard in various ways. But not being obligated to not be a dick doesn’t mean you should in fact be one.

This is the sort of immature "well, actually" response that you can't afford anymore once you actually take responsibility for things. I wish more people trained themselves to have a "what if I had to do it" habit before having an opinion.

Imagine you're in charge of the train network. You have to pay for the announcements on trains. You can't reasonanbly pay 10 announcements because that's silly and expensive. If you add any language other than German, which are you going to add?

It's not hard to be pragmatic.

Cheap strawman. Travelling Swedes, Danes, Finns and Poles will be fine with English, Dutch with either/both English or German.

Look, as an EU country citizen, English is more or less the defacto language of the EU, regardless of what politicians declare. Everyone in the EU speaks english in some form as even traveling to a next door country like you state requires communication.

There are cases where in Belgium you will see signs in 4 languages (Dutch, French, Flemish and English)

Also if you ever travel in Japan, they have signs, especially on trains, all in, Japanese, Chinese, Korean and English all in one. (usually rotating signage). So the precedent is there to do it on mass transit but :shrug:.

Point is, when your customer base is logically needing more language options, it should be considered.
