At Seashore, the convertible car design is exemplified by No. 4547, built for Brooklyn in 1906 by the Jewett Car Company of Newark, Ohio. There are 12 removable windows and panels on each side and during the years that the car was in regular operation, these were replaced by heavy metal grilles during warm weather. It has transverse seats except for short longitudinal seats at the ends, and a center aisle, with both exit and entrance made through end doors.
