an additional set in 1938 collectively known as the B-2's. The JG Brill Company also built and delivered 26 deluxe art-deco streamlined subway cars to the Delaware River Joint Commission in early 1936 for use on its Bridge Line from 8th and Market into Camden, NJ via the Benjamin Franklin Bridge. These cars were designed to be compatible with the other Broad Street cars, and could run in multiple with them. After the Bridge Line became part of the PATCO Lindenwold Hi-Speedline in late 1968, 23 of these former "Bridge Line" cars were sold to the City of Philadelphia in 1969 to be used on the Broad Street subway, and were designated as the B-3's, until they were retired by early 1984. The first set has had the second longest lifespan of any subway car in Philadelphia, after that of the Market Street cars built for what ultimately became the Market–Frankford Line. Although the line was a host for the UMTA's State of the Art Car program, real replacements for the Broad Street cars did not come until late 1982, when SEPTA introduced new "B-IV" cars built by Kawasaki, which are currently the only cars operating the line. The cars are 67ft 6in long, 10ft 1.5in wide, and 12ft 3in tall. Preservation A small number of B-1, B-2, and B-3 historic cars remain stored in derelict condition within Fern Rock yard. One B-1 car was sent and sold to the Trackside Brick Oven Pizzeria in Wallingford, Connecticut. One B-1 car (#55) is present at the Illinois Railway Museum. One B-3 car (#1009) is partially restored at the Rockhill Trolley Museum. Two B-3 cars (#1018, #1023) are at the Seashore Trolley Museum.
