Several companies with highly specialized teams are at work to ensure our red and yellow vehicles are in top shape for service. Among other things, the S-Bahn Berlin maintains the vehicle fleet, while the DB Stations & Service is responsible for the construction and operation, as well as the maintenance and production of stations. The tracks, the switches and the signals of the S-Bahn Berlin–which, in addition to the track systems and crossings, includes the Electronic Interlocking System (ESTW) and signal boxes –are cared for by the DB Netz. Regular maintenance and repair work is needed to keep the 327-kilometer network in excellent condition.
Whether it be station repairs, track replacement, or the installation of the train control system (ZBS), these construction projects are planned well in advance in order for them to work collectively. The construction companies work hand in hand with us to minimize any burdens on our passengers.
We like to keep out construction projects in the "background" of the average commuting day; however, despite all our efforts to do so, at times they take on a considerable presence.
