With the reunification of the city and the decision to restore Berlin as Germany's capital and thus the seat of government, the Berlin S-Bahn entered a new era: it was again to become the backbone of public transport in the city, an integrated element of the local transport system in the region.

The continuous rise of passenger numbers from 246 million five years ago to over 290 million (2000), as well as the average punctuality rate of 97.7 per cent in the year 2000 - despite numerous construction sites in the network - are clear evidence of the professional, customer-oriented work of the staff day after day. These figures also show that S-Bahn Berlin GmbH is on the right track.

After decades of stagnation, billions are being invested to restore the train stations to their former glory. Particularly the important interchanges at Alexanderplatz and Friedrichstrasse, as well as Potsdamer Platz and Lehrter Stadtbahnhof, have again become centres of metropolitan life with the arrival of hotels, industry, trade and shopping arcades.
