After 109 years of operation, the American Locomotive Company had produced 74,999 locomotives. On September 19th, 1946 with much celebration the 75,000th ALCo locomotive rolled out of the erecting shop. That locomotive, was Santa Fe #51, a brand new model PA dressed in that road's famous red and yellow "Warbonnet" livery. The model PA, first referred to as the "2000" in reference to its horsepower rating, was ALCo's first attempt at creating a passenger diesel locomotive. The ALCo PA was an inspiration of the art deco styling that had begun with the streamliners of the thirties and continued into the postwar years. The #51 went on to pull the famous streamlined varnish of the Santa Fe such as the mighty Super Chief. The locomotive was so powerful that it could pull 15 cars, or 1265 tons, over the 3.5% grade of Raton Pass without a helper.  By 1967, almost all of the PA's were retired by the Santa Fe. During that holiday season, the president of the Delaware & Hudson gave his railroad quite a Christmas present when he purchased four retired Santa Fe PA's and had them fully refurbished. They continued to work for years on the D&H's signature passenger service.  All-new from the ground up, the Lionel models accurately replicate the PA-1 body design, including metal, see-through screen detailing, dynamic brake openings and pivoting diaphragms on the rear doors. The authentically detailed, die-cast metal trucks are based on the single-equalized A1A design. The Santa Fe PA A-A set even includes an all-new, highly realistic Mars light with pulsing on/off action, creating a much more realistic effect than a simple flashing light.  Matching PB B-units are available for each ALCo PA A-A set.
