DBAG 772 153-3 at Hennigsdorf. In the background you can
see that this track ends and the S-Bahn track begins a few
meters further behind; this separation was necessary for
electrical reasons (separation of AC and DC circuits). RB 
55 (Hennigsdorf - Kremmen) is currently operated with class
772 railbuses.
