These MEGV locomotives would not have been known for their elegant profile. A tall, slightly tapered drum housed the steam, a slender stack supported a broad, inversely tapered spark-arresting top. All motion lay outside.
The trio only briefly bore the road numbers and MEGV before being taken into the MAV in 1891 and being renumbered.
After World War One, the trio were given to the new Yugoslavian State Railway, but were withdrawn by 1920.
