Rail City Berlin: Reunification, Infrastructure, and Urban Mobility
by Nala Thomas
Overview
This section summarizes my presentation on Berlin’s rail infrastructure and how the city’s transportation system evolved through division, reunification, and redevelopment. Berlin is often described as a “Rail City” because its dense, multimodal rail network has shaped everyday mobility for more than a century. The focus of this presentation was on how Berlin’s historic rail structure both created open resilience and revealed challenges after reunification.
My presentation is based on the academic article “Rail City Berlin – Rail Infrastructure Development and Inter-modality in the Re-Unified German Capital” by Dr. Deike Peters, which examines Berlin’s rail system before, during, and after the Cold War, with special attention to post-1990 planning decisions.

S-Bahn network today, with Ringbahn and Stadtbahn as backbone. Published by Deike Peters
Berlin’s rail network is structured around two historic rail corridors built in the 1880s that are still the backbone for the system today.
The Ringbahn is a circular commuter rail line that loops around Berlin’s inner city. It was originally built to connect multiple terminal stations on the city’s outskirts and later became essential for everyday commuter travel.
The Stadtbahn is an elevated east–west rail corridor running directly through central Berlin.
During the Cold War, Berlin’s rail system was physically and politically divided.
East Berlin relied heavily on the S-Bahn
West Berlin expanded the U-Bahn and abandoned the S-Bahn
“Ghost stations” existed where trains passed through East Berlin without stopping
Tram service survived only in the East
Post-reunification planners created this new “Mushroom Concept” (Pilzkonzept), which centered the system around a new north–south rail tunnel and a new central station: Berlin Hauptbahnhof. (We visited this station in our LC)
In 2009, Berlin experienced its worst rail crisis since World War II when safety failures led to the sudden removal of a large portion of the S-Bahn fleet.
Major lines were shut down
Emergency schedules replaced normal service
The crisis exposed governance and maintenance issues within Deutsche Bahn
Despite this, Berlin’s dense, multimodal system allowed the city to continue functioning through U-Bahn, trams, buses, biking, and walking, highlighting both the strength and fragility of complex transit systems.
