The railcars 800 to 804 were procured for the Ravensburg-Weingarten-Baienfurt interurban tram after it had been electrified in 1910 with 750 V direct current. Although the line was in Württemberg, it was operated by the Bavarian Localbahn-Aktiengesellschaft.

The vehicles had a total length of just over 13 meters and stood on two two-axle bogies, of which the outer axle was driven. Each was driven by a nose-suspended motor with a continuous output of 33 kW, which was initially supplied with electricity by a Lyra pantograph. Later these were first replaced by one and then by two diamond-shaped pantographs. Behind the six windows on each side was a seating group each, four of which belonged to the third class and two to the second class. In the third class there were two people on each side, facing each other, and in the second class there was a transverse, padded bench for three people on each side. This resulted in a capacity of 43 people.

If a higher passenger volume was to be expected, regular narrow-gauge passenger cars could be carried as trailers. The operating conditions and the available motor power limited the train load to two two-axle or one four-axle car. It was not possible to get from the railcar into the trailer while running.

The Reichsbahn started a rebuild in 1928, replacing the air brakes with modern magnetic track brakes. In addition, a few years later, the second-class compartments became third-class, which increased the number of seats to 48. From 1941 they were designated as ET 195 and kept this designation later on at the Bundesbahn. After they were first dark green, then from 1936 lime green with a beige window band and later beige-light red, they were given the typical maroon color scheme at the Bundesbahn. Since the use of newer vehicles from 1954, they were only used as reinforcement trains, but they remained in service until the line was closed in 1959.
