These are one of my favorite diesel units from the German Railways... Nice capture although the overhead wires are a bit annoying... but about those we cannot do much!
Hah, well, I like noisy trains. As for uncomfortable... Well, I would have to try it myself. But honestly I have heard that your "comfort" standards on regular trains is rather very good comparing to what we have here so its very probable I would like the comfort of these units.
Die Linie kenne ich gut, wenn auch an ihrem anderen Ende (der Hannover-Goslar Teil). Die Wagen sind laut, die Einstiege zu hoch, und die Kapazität eigentlich immer zu niedrig.
