Economical Transport for the Windy City 1921 Chicago Surface Lines Birney Safety Car A Bumpy Ride By the early 1920s Chicago had grown so large that more and more trolleys were needed. But some had low ridership so the bigger 2-man operated trolleys were too costly for the Chicago Surface Line company. To solve this problem, in 1921 10 Birney Safety cars were purchased. These 1-man operated trolleys, called Safety Cars because of the “kill” button that stopped them instantly) were used on the less-traveled routes. They provided an efficient although bumpy ride until they were replaced in 1937. Features • 6" Long • 1:48 Scale Model • O-Gauge Compatible • Precision Die-Cast Replica
