 In 1983 the second track was restored to the section between Werder and Berlin-Wannsee.With the completion of the electrification of the Griebnitzsee–Brandenburg an der Havel–Biederitz section in December 1995, Intercity-Express trains could now take the direct route via Brandenburg instead of the now partially closed route through Bad Belzig and Güterglück (the strategic railway known as the Kanonenbahn, the "Cannons Railway").At the same time the line was upgraded for a top speed of 160 km/h.
