The MGB has awarded the contract for the renewal of nine of its originally 13 cogwheel locomotives HGe 4/4 II built between 1986-1990 to SBB following a tender. The prototype was the HGe 4/4 II 106. It was completely stripped down and reusable parts were overhauled. The so-called refit includes the replacement of the main components. Visibly, in addition to the slightly altered design and the LED headlights, the modern air conditioning unit between the bogies is particularly noticeable. After the completion of the work in 2021 and a successful performance test, two locomotives were each added to the refit program. This includes, in addition to the eight locomotives 101-108 procured by FO, the HGe 4/4 1 of the BVZ as the ninth locomotive.
