With a total of 12 coaches, the Reko coaches of the pilot production was the smallest part of the Deutsche Reichsbahn's Reko program. The coaches were manufactured in 1958 and tested for about a year before they went into series production. On the outside, the Reko coaches of the pilot production differed from the coaches of the series production only by four side doors that had a smaller design. Tests were carried out when passengers boarded and disembarked from the trains. The tests showed that Reko coaches with diagonally arranged doors were the best concept. The toilet was moved to the vestibule. Thanks to this design modification, it was possible to create space for four more seats. The side windows of the serial Reko coaches had a larger design and the compartments were enlarged as well. Despite their special position in the vehicle fleet, the coaches, like their successor models, were used for a long time and could be found in various types of train compositions.
