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.
