The so-called St. Louis cars havecross seats, but these are not well adapted for Berlin streetservice, as the cars on several lines are only 2 m (6 ft. 6ins.) in width, which is hardly sufficient for this type ofcar. The trucks were furnished by the Bergische Stahl In-dustrie. The side frame for the single trucks, which areof the model Berolina, are large steel castingsunited by flat iron cross-bars. The wheel-base on thesingle trucks is m (5 ft. 9 ins.), and on the doubletrucks, m (3 ft. 7 ins.) The double trucks were de-signed by Chief Engineer S.
