This is prompted by a question in r/NoStupidQuestions concerning a Holocaust survivor who reportedly made her way to Israel in 1942. So we don't know her starting country nor route.

There's a reasonable question as to whether her recollection of using a train to escape could be accurate, and if so, where. I speculate that a land route could have gone through Turkey, but I imagine there was very little train traffic (and perhaps no passenger traffic) to Istanbul during the war, and I have no idea as to what rail routes, if any, existed either within Turkey or between Turkey and British controlled areas at the time.

I don't know whether the possibility of escaping even partly by rail through Nazi occupied or even Nazi aligned countries (e.g. Bulgaria) is at all realistic or just the stuff of movies.

Or would a sea route, say overland through Greece and then by boat, have been more likely?
