MÁV, the train operators of Hungary, have special ticket prices from Budapest to locations around Europe. I got a ticket from Budapest to Munich for €29.
[Budapest to Munich]
The tickets aren’t apparent to find online. I only knew about the ticket offer from billboards in Budapest and there is no indication of the special price tickets online. I had to get a local buy the ticket on my behalf before I arrived.
Tickets available from Budapest include:
€29: Venice, Munich
€39: Baden-Baden, Berlin, Hannover, Hamburg, Zurich, Strasbourg
€42: Frankfurt, Mainz, Bonn
The best way to book this ticket is to use the German Railways booking site bahn.com.
The train from Budapest to Munich is operated by ÖBB of Austria. I was happy to find powerpoints and fold out tables available for laptop users.
