Alb Valley Railway
The Ettlingen West–Ettlingen Stadt line was built as a dual gauge line and services were integrated into the Alb Valley Railway. The dual gauge track was extended to Busenbach in 1899 and to Etzenrot in 1906 to improve access for freight traffic. In 1898, the Alb Valley Railway was taken over by the "Badische Lokal-Eisenbahnen Aktiengesellschaft" (Baden Local Railway Company, BLEAG), a newly formed subsidiary of the "Westdeutsche Eisenbahn-Gesellschaft" (West German Railway Company, WeEG).
