Stadler vs. SBB: Swiss Rail Contract & Double-Deck Tech Analysis

Introduction

Stadler has expressed disappointment following Swiss Federal Railways’ (SBB) decision to award a framework contract for up to 200 double-deck trains to Siemens Mobility. The contract, announced on 7 November 2025, includes an initial order for 116 units, with an option for an additional 84 trains, destined for the Zurich S-Bahn and western Switzerland.

Stadler’s Reaction

Stadler stated its “great regret” at the decision, highlighting its position as a “proven Swiss manufacturer of double-deck technology.” The company noted the price difference between its offer and Siemens, calculated over 176 double-deck trains, was 0.6 percentage points. Stadler, with approximately 6,000 employees in Switzerland, indicated that its bid was “only 0.6 per cent more expensive than Siemens.”

Stadler’s Track Record

Stadler emphasized its history as a supplier of double-deck trains to SBB and other international operators. The company’s KISS fleet has been operating on the Zurich S-Bahn since 2012 and is used in 14 countries. Stadler CEO Markus Bernsteiner stated that their double-deck trains have a 99% availability rate.

Domestic Impact and Manufacturing

Stadler has sold around 700 KISS double-deck trains globally, including 192 units in Switzerland. The company manufactures trains for the Swiss market at its plants in Bussnang (Thurgau) and St. Margrethen in the St. Gallen Rhine Valley. Stadler estimates that up to 80% of the production value remains in Switzerland. Over 200 SMEs supply components to Stadler, and the company employs over 16,600 staff worldwide, with approximately 6,000 based in Switzerland.

SBB’s Procurement Process

SBB stated that public procurement rules prevent favoring domestic suppliers. Equal treatment and non-discrimination are strict legal requirements in BöB/VöB procedures, preventing preferential scoring based on national origin. SBB noted that Swiss manufacturers have received the majority of rolling stock orders over the past 25 years.

Conclusion

Stadler will analyze the details of SBB’s assessment. The company affirms its commitment to the Swiss market and will continue investing in railway technologies, training, and infrastructure.
