In order to increase the power of the ABDeh 6/6, the BVZ had three ABDeh 8/8 built in 1965. While the two car bodies of the predecessor were supported in the middle on a common Jakobs bogie, both car bodies now each had two bogies of their own. This now meant eight driven axles and an output of 1,176 instead of 882 kW. Here, too, there was a rack drive in each bogie. The transformer was now under the floor.

The three sets were given the names “Brig”, “Visp” and “Zermatt”. They were used together with their predecessors, but were able to tow an additional trailing load of 175 instead of 132 tonnes. They were retired in 2008, 2011 and 2014, shortly after their predecessors. The number 2042 “Visp” was initially intended to be given to a club for preservation. However, since the refurbishment would have meant very high costs, it was also scrapped in 2017.
