This car was the centerpiece of operation on the Zittau Narrow Gauge Railroad up to the change in daily passenger service. Thus chiefly after the turn of the millennium excursion service and historic trains were added. An attempt was made at that time to increase the attractiveness of the railroad with a new paint scheme - green/ivory. More than just the color was new. The cars were also equipped with the sliding windows typical for the Zittau Narrow Gauge Railroad, on which the complete upper half could be opened. This was at the strip, which divided the window into an upper and a lower half, and which is easy to recognize. The paint scheme looked very beautiful on these old cars, but it was then replaced by a completely green paint scheme with large lettering "Zittauer Schmalspurbahn".
