| Here is the back portion of the wrap-around color cover of the Pennsylvania Railroad Company's 109th Annual Report for the Year Ending 31 December 1955. The photographer is not identified. On page 15, it is noted that "1956 will be marked by the introduction of new types of passenger equipment by several railroads. The first of these to appear was the General Motors 'Aerotrain,' which is shown on the cover of this report. It is now in experimental service on your railroad." |
