The second construction phase of the construction work on the Berlin Stadtbahn begins on Monday, July 18th. From 4 a.m. the S-Bahn connection between Ostbahnhof and Friedrichstrasse will be closed. According to Deutsche Bahn, the blockage will be lifted on Thursday, July 28, at 1:30 a.m.

Lines S3, S5, S7 and S9 are affected. According to the transport company, the reason for the blockage is work on the tracks and points. Accordingly, tracks at the Ostbahnhof will be repaired and the points at the Alexanderplatz and Friedrichstrasse stations will be renewed.

A replacement service with buses will be set up, which will run every five minutes. However, the buses cannot stop at Hackescher Markt, reports Deutsche Bahn. The company advises passengers to use the M1 tram between Friedrichstrasse and Hackescher Markt train stations and the M4, M5 or M6 tram lines between Alexanderplatz and Hackescher Markt instead.

According to the information, the regional trains RE1, RE2, RE7 or RB14, RB21, RB22, which run parallel to the Stadtbahn, are not affected by the restrictions in the S-Bahn network.

With the start of work on the second construction phase, the closures of the first construction phase will end on Monday morning. Since Monday, July 11, the S-Bahn route between the Alexanderplatz and Zoologischer Garten stations has been closed.

The S-Bahn line between Grünau and Königs Wusterhausen is also closed until August 22, also due to construction work. Line S46 normally runs there.

Deutsche Bahn regularly uses the holiday periods for their major construction projects. The background to this is that fewer passengers tend to use local transport during these phases because many commuters are on holiday.
