DB Regio Nordost is one of the principal TOCs (Train Operating Companies) operating stopping and semi-fast rail services in the North East of Germany, comprising the states of Mecklenburg-Vorpommern, Berlin and Brandenburg, with some lines also extending into Sachsen-Anhalt (Saxony-Anhalt), Sachsen (Saxony), Hamburg, and Western Pomerania (Pomorze Zachodnie) in Poland.
Staff is mostly friendly, especially on the RE1 line between Frankfurt (Oder) and Magdeburg by way of Fürstenwalde (Spree), Berlin, Potsdam and Brandenburg/Havel, branded as the first Regional-Express service in Germany that started its success story about 20 years ago. They are usually bilingual and will gladly give you information in both German and English. Some also speak basic Polish or Russian. Tickets cannot be bought onboard anymore except for select few rather expensive tickets (1st class excess, Rail Rovers for Berlin-Brandenburg or the entirety of Germany), but these can be paid for by credit cards and now also by debit cards.
Trains are fairly clean and refurbished to comparatively high standards with power sockets in both first and standard class. Much more so than in certain other regions (Yes I'm looking at you DB Regio NRW) - probably also because the Berlin-Brandenburg Passenger Transport Executive (VBB, Verkehrsverbund Berlin-Brandenburg) is constantly watching the conduct of the regional transport companies. read more
