SBB completes six-year rail upgrade in the Basel area

After six years of construction SBB, on behalf of the federal government, completed the main works on six projects in the Basel area on schedule, including the expansion of the platform complex at Basel SBB station (an additional platform, a temporary footbridge), the upgrade of the access line from Muttenz and the southern stabling facility; the four-track expansion at Liestal and the Grellingen–Duggingen double track come on top, and the federal government and parliament invested over CHF 1 billion in total. With the timetable change on 14 December 2025 a 15-minute S-Bahn service between Basel and Liestal and half-hourly long-distance trains on Basel–Delémont–Biel/Bienne start, one an hour continuing to Lausanne and the other run by BLS with low-floor trains; it is the biggest service expansion in north-western Switzerland since Rail 2000. The platform expansion in Basel is also a prerequisite for future S-Bahn through-services to Alsace and a 15-minute service between Basel and Aesch. (LOK Report, 28 Nov 2025)
