An underground line was to run from Delmenhorst through Huchting, Bremen Airport, the city center, University of Bremen, and Borgfeld and end in Lilienthal. Line S 1 was to run from Schwanewede through the city center, Sebaldsbrück, Mahndorf, and Achim and end in Verden. Line S 2 was to run from Osterholz-Scharmbeck through Ritterhude, Marßel, Burglesum, Findorff, University of Bremen, Oberneuland, and Rotenburg. The third line was planned to go through Delmenhorst, Huchting, Neustadt, city center, Hemelingen, Kirchweyhe, Syke, and Twistringen. A temporary panel of the Bürgerschaft, which gathered the findings after 19 months of planning, presented the results as an alternative to automobile-based transportation. Pedestrian zones, closely spaced stops, and park and ride lots at the termini of the lines were planned as well. Due to financial and technical difficulties and political opposition, these plans were not realized.
