Just a little bit of fun that I discovered if you have Bremen-Oldenburg route installed. Enter timetable mode on foot at Bremen Hbf at around 10:20am, and you might be surprised to see a BR155 pull into the station on an unannounced ECS move. I don't know where it's going, as I'm still sitting on the thing heading towards Oldenburg, but it's not every day you get to ride in a Doppelstock car behind a BR155.
