Stadler Drops $2.48bn SBB Appeal After Court Documents Remain Redacted

Stadler has withdrawn its appeal against Swiss Federal Railways' (SBB) decision to award Siemens Mobility a $2.48bn contract for 200 double-deck EMUs on April 7. The Swiss manufacturer dropped its Federal Administrative Court challenge after receiving heavily redacted documents that provided only partial clarity on SBB's procurement decision.

The withdrawal removes a major legal obstacle to Europe's largest EMU procurement but exposes persistent transparency issues in Swiss public contracting. Stadler's inability to access critical evaluation criteria despite formal court proceedings highlights the challenge suppliers face when contesting public sector awards. This outcome may discourage future appeals from unsuccessful bidders who cannot obtain sufficient documentation to mount effective challenges.

Stadler filed the appeal in November 2025 after SBB selected Siemens' untested design over the proven Kiss platform. The manufacturer argued it could not understand how SBB reached its decision, particularly given that 153 Kiss EMUs already operate on SBB's network with 99% availability. The framework contract covers 116 firm orders worth $2.48bn, with options for an additional 84 trains. Siemens will deliver a new six-car double-deck design that has yet to enter production or undergo operational testing.

The case underscores growing scrutiny of major rail procurement decisions across Europe, where domestic manufacturers increasingly compete against international rivals. Stadler's withdrawal clears the path for Siemens to proceed with detailed design work and production planning for what represents one of the largest EMU orders in European rail history. SBB expects the first trains to enter service by 2029.
