According to research and documentation, during the 1920's decade, the BMT AB's were modified with a nine point jumper cable for a full train with MUDC, so that only one conductor controlled a train door's operation. When installed on a car, it carries an extra "A" prefix to its classification.As cars were modified, "AA", "AB" and "ABX" units were created. The extra "A" was used only during this modification period, and when the entire fleet was completed (by the year 1930), the extra "A" was dropped.
