i2030
Strengthening rail capacity in the Berlin-Brandenburg region in Germany
AFRY supports planning and engineering within the i2030 program, focusing on capacity and reliability across key rail corridors.
The Berlin rail network is reaching its limits due to increasing commuter numbers, with trains operating at very high occupancy during peak times. To address this, the federal states of Berlin and Brandenburg, together with Deutsche Bahn and the Verkehrsverbund Berlin-Brandenburg (VBB), initiated the long-term i2030 project. The objective is clear: to expand capacity, reactivate routes, reduce delays and create a robust transport system for the capital region.
AFRY's teams contribute their planning and engineering expertise to develop innovative solutions for local, long-distance, and freight transport. The goal is to significantly improve daily mobility for millions of commuters between Berlin and Brandenburg and to create a future-proof, sustainable transport system.
Strategic corridors for tomorrow’s transport
The i2030 project focuses on the most critical sections of the network. It includes multi-track lines and new or modernized stations, enabling new connections, shorter intervals, better interchange options and higher reliability for both passenger and freight traffic.
The Berlin rail system has evolved over nearly two centuries
Since 1838, when the Potsdam railway was opened, the network has continuously developed. Today, more than 1.4 million people use the S-Bahn daily. Through the comprehensive i2030 infrastructure program, the capital region is significantly investing in transport infrastructure for the future.
AFRY’s projects in the i2030 program
S25 North Berlin-Schönholz – Hennigsdorf
Double-track expansion between Berlin-Schönholz and Hennigsdorf to enable a 10-minute interval.
- 16 km corridor
- 24 bridges
- 6 railway stations to be built or expanded
Potsdam Main Line
Reactivation of the first Prussian railway line between Potsdam and Berlin to relieve pressure on neighboring lines. The alternative route will increase the capacity of the Berlin rail network.
- 26 km corridor
- Approximately 80 bridge structures
- Redesign of 6 transport stations
Southern Berlin inner ring
Expansion and electrification between Berlin-Schöneberg and Berlin Ostkreuz.
- 12 km corridor
- Approximately 30 bridge structures
- Expansion of 4 transport stations
S2 North Berlin-Buch – Bernau
Construction of a second S-Bahn track to increase service frequencies and capacities, as well as to ensure the robustness of the transport system.
- 9 km corridor
- 19 bridge structures
- 2 transport stations requiring fundamental reconstruction
Berlin-Spandau – Nauen
Expansion of one of the busiest S-Bahn, regional and long-distance rail corridors with new or renovated stations and increased line speeds.
- 23 km corridor
- 35 bridges
- 9 new train stations to be built or expanded
Berlin-Spandau – Berlin Central Station
Feasibility study to eliminate bottlenecks on the approach via Jungfernheide to Berlin Central Station, in order to enable parallel entry and exit routes.
- 13 km corridor
- 40 bridges
- 1 station to be expanded
