The StadlerRail railcar RBDea 567 # 173 leaves Erlen as train 39331 to the Stadler plant in Altenrhein. The vehicle was delivered to RVT (Régional de Val de Travers, now TRN) in 1983 as RABDe 4/4 # 104. In 1991, the railcar was sold to the then GFM (Gruyere-Fribourg-Morat) and today TPF (Transports publics fribourgeois), where it was later modernized with air conditioning and the elimination of the first-class compartment with the new designation RBDe 567 # 173. In 2022, the railcar was sold to StadlerRail as a towing vehicle for transfer journeys. It was newly equipped with a battery for "last mile" operations on non-electrified tracks and is now RBDea.
