Bodensee Belt Railway partners fund design planning with EUR 42.9m

The planning phases are funded with EUR 42.9 million: the state pays half, Bodenseekreis 30 and Konstanz district 20 per cent. Preliminary planning puts the total cost of the upgrade (overhead wires, several double-track sections, station rebuilds, three new stations) at about EUR 650 million (2022 prices).

Announced on 10 November 2025: the four partners signed the agreement for design and approval planning (phases 3 and 4); next, DB will tender the general planner, followed by surveys on noise, vibration and ground conditions. The transport ministry expects approval planning to finish only in 2030, so a state MP expects a building permit in 2032 at the earliest and criticises a two-year delay; the reports give no completion date (LOK Report, 10 Nov 2025).
