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.

Pragmatic is multiple languages in locations where it's highly relevant.

For example, the UK Gatwick Express train makes announcements in English, French, German and Spanish.

The Thameslink service (which also happens to travel on the same tracks and also happens to stop at Gatwick Airport) makes announcements in English only.

I wouldn't expect local or regional trains in Europe to make announcements other than in that country's native language – except perhaps where it's a service designed for airport connections or similar international travel.

Given the demographics? Turkish or arab
