The headquarters of the Kasernierte Volkspolizei (the militarised unit of the East German police, which was transformed in 1956 into the National People's Army) was moved in June 1954 from Berlin-Adlershof to Strausberg, because Berlin had been declared a demilitarised zone by the four occupying powers.

After Die Wende (the turn) there were suggestions that the line be closed and that at the same time the parallel Strausberg Railway should be upgraded.

[2] As a further means of stimulating passenger growth individual services of Regionalbahn line RB 26 ran during peak hours between Berlin-Lichtenberg and Strausberg Nord during the 1998/99 timetable period.

Around 2000, the travel times on the S-Bahn from Berlin Alexanderplatz to Strausberg were shortened by nearly five minutes as the result of the modernisation of the fleet.

This in turn led to calls for an increase in services on the line to a frequency of 20 minutes, but the construction of a second track in the area of Hegermühle station would be necessary.

The commissioning of the crossing loop and the upgrade of operations to 20-minute intervals to Strausberg Nord was made at the timetable change on 13 December 2015.
