The winter is coming, yes, and the troubles fot the S-Bahn too.
Ok maybe the winter is not the reason for the problems that distress the S-Bahn, but surely cold, rain and snow make the situation worse.
So this weekend S25 isn’t available, but there is a replacement bus.
Also S1 needs some maintenance at Schönholz stop.
Also a replacement bus for the line S5, between Strausberg and Strausberg Nord stations.
Any other info here.
