SEMT ピルスティク
Between 2002 and 2004, thirty locomotives were rebuilt with SEMT Pielstick engines, after which they were re-designated as SNCF Class CC 72100. The original power units had been considered to be noisy and smoky, which had led to a ban of the type by Swiss authorities from Basel’s SNCF station in the early-2000s. The rebuilt locomotives are numbers: 21, 30, 37–41, 43, 45, 47, 48, 51, 56–60, 63, 66, 68, 72, 75–80, 82, 86, 89–90.
