No... they always got the right of way. Better than car splatter for the next few miles, because a train does not bounce away in a collision(which is what happens when 2 cars collide, there is a bounce away) Car vs train= grind away for the train does not stop.
If you don't like it you can always MOVE.

This page shows the London and Paris to Istanbul, but trains go both ways around and from Paris to Berlin is easy to buy and add to the main ticket(s)

You can see that there are a few different options.
It is well possible that one of the routes given is via Frankfurt, in which case you just buy your ticket to there.

In your case I would contact the German rail people, they are very good in selling ticket for all of Europe, but only for Germany through the automated system.

I opened the page to the details of the DB travel services, likely you will have to open it again: http://www.bahn.de/p_en/view/booking/tic...
In the lower part of the page, in the list under 'there are other ways to buy tickets'.

Likely you can buy the tickets online, but as it is a difficult one, I guess that contacting the train people of the country you travel to will be most useful.

Out $20 . Call your lawyer. Write the Newspaper Picket in front of the Train station. Swear a Public Oath never to ride Public transit again..Hit em where it hurts. Never Buy another ticket.

I notice you did arrive safely and are able to complain about the ride.
