This is supposedly the first car from Arad-Podgoria line. Although it bears the BFam0601 inmatriculation number, there are some clues that this is actually BFam0605 or 06.  Originally built by Henning & Hartwick in Berlin as petrol-fueled motor units with electric transmission, these (a total of 11 cars) were later modified by Johann Weitzer Arad after the electrification of the line. Engine was removed, and its place was taken by a luggage/post compartiment. 
The yellow device in the foreground is 30-ton elevator from 1906. Seen in the Museum in Ghioroc.
