The Coradia Max platform represents Alstom’s answer to Germany’s growing demand for regional trains that can handle heavy commuter flows while meeting modern comfort and environmental standards.
Why Baden-Württemberg Needs New Trains
Baden-Württemberg, home to Stuttgart, Karlsruhe, Heidelberg, and Freiburg, is one of Germany’s most densely populated and economically powerful states. Its regional rail network faces significant challenges:
Growing Demand
- Population: Over 11 million residents
- Economic Powerhouse: Home to Mercedes-Benz, Porsche, Bosch, and SAP
- Commuter Flows: Heavy daily traffic between Stuttgart and surrounding cities
- Tourism: Black Forest, Lake Constance, and Rhine Valley attract millions of visitors
- University Cities: Heidelberg, Freiburg, Tübingen generate student commuter traffic
Aging Fleet
Many regional trains in Baden-Württemberg date from the 1990s and early 2000s. The new Coradia Max trains will:
- Replace older, less efficient rolling stock
- Increase passenger capacity on crowded routes
- Improve reliability and reduce maintenance costs
- Enhance passenger comfort and accessibility
- Meet stricter environmental standards
The Deutschland-Ticket Effect
Since the introduction of the €49 Deutschland-Ticket in May 2023, regional train usage has surged across Germany. Baden-Württemberg has seen particularly strong growth, putting pressure on existing capacity. New double-decker trains are essential to meet this increased demand.
Where Will the Trains Operate?
While specific route assignments have not been confirmed, Baden-Württemberg’s busiest regional corridors are likely candidates:
| Route | Current Situation |
|---|---|
| Stuttgart S-Bahn network | Heavily used suburban services |
| Stuttgart — Karlsruhe | Major intercity regional corridor |
| Stuttgart — Heilbronn | Commuter-heavy route |
| Karlsruhe — Basel | Rhine Valley traffic |
| Stuttgart — Tübingen — Reutlingen | University commuter route |
| Mannheim — Heidelberg — Stuttgart | Key economic corridor |
The double-decker configuration is particularly suited to routes with high passenger volumes but limited train frequency, allowing more travelers per service without increasing the number of trains.
Alstom’s Growing Presence in Germany
This contract reinforces Alstom’s position as a major supplier to the German rail market. The company has significant manufacturing and engineering presence in Germany following its acquisition of Bombardier Transportation in 2021.
