DSB plans fully automated GoA4 system for Copenhagen's S-trains

DSB's "Future Rail Network" programme aims to convert Copenhagen's S-train network into a fully automated, driverless GoA4 system over 15 years. After an Expression-of-Interest phase (2019) and a market Request for Information (responses due September 2019), the project according to the source is still in an early concept/planning stage and is tied to the upcoming replacement of the oldest S-trains, which reach their regular retirement age from 2026 onward. If completed, it would become the world's largest driverless mass-transit system; the source states no fixed completion year, so the end-2030 horizon from the original source list is retained here.
