Ship Last Trolley Car to Plant for Conversion
The last “green hornet” street car scheduled to be converted into an elevated-subway car was shipped Monday by the Chicago transit authority to the St. Louis Car company, St. Louis. It was the last car used on the Wentworth route, which switched to buses June 21. The St. Louis firm is converting 100 of the street cars into “L” subway cars. When this order is completed, the CTA will have transformed 570 “green hornets” into “L” subway trains.
