VLO - Germany
According to Wikipedia, this is coach (Beiwagen) TA 8 owned by Verkehrsgesellschaft Landkreis Osnabrück. Another picture on Railfaneurope.net shows it as T3 of Museumseisenbahn Minden. But MEM does not have a T3, VLO however does have one. In any case this is an original vehicle of Wittlager Kreisbahn, that later became VLO.
