Unlike the Gotthard, everything I saw on the Biel - Lausanne line was worked by SBB motive power, with one exception. PSE 3-Voltage set 117 rolled south from Cossonay while working TGV9269, the 11:57 from Paris Gare de Lyon to Lausanne on 6 September 2012. These units were versions of the original TGV sets built in the mid 1980s and were withdrawn by the end of the year.
