Here is an anecdote that somehow fits to it, one without a definite conclusion.

One day I travelled from a countryside town back to Budapest on an IC. I sat at the very end of the train. On the opposite side of the aisle, two girls with darkish skin were sitting, and one row forward a boy, I first thought they're Carribean. Theywere well-clad, but looked tired.

I went to the toilet, and once back, I saw the conductor talking to them. They wouldn't understand anything, but it was pretty clear they had no ticket. They didn't undestand "passport" or "identity card" or "Identitätskarte" either, so the conductor asked me if I speak French, because the boy seemed to speak it. But even in French, all I could get out of them is that they have no money (smiles). so I formed a square with my hands, then the girls said: "Aaah, police card!", and handed theirs to the conductor, who wrote them up then left.

Ten minutes later, the trio began to talk among themselves. I could catch some words -- they were German, in a very heavy dialect. Interesting... Half an hour later, one of the girls went to the toilet. She took a long time. When she came back, the tight jeans and dress were gone: she had headscarf on and a long robe! Minutes later, the other girl went to the toilet, and came back similarly changed.

I have no idea what I saw, but dreamt up several possible back-stories...
