Description

Pennsylvania Railroad S1 No. 6100 was the darling of the 1939 Chicago World's Fair. Her tender was lettered "American Railroads", she represented the latest development in steam power and design. Built at Juniata Shops in Altoona, Pennsylvania, she was the biggest locomotive in the world! Some will argue, that the Union Pacific "Big Boy" freight locomotive was the bigger, but the S1 was 140' 2.5" stem to stern, the Big Boy was only 137' long. Although not as successful as the UP Big Boy, she was certainly the most beautiful of the two with her sleek Raymond Loewy streamlined styling. Built for high speed passenger service, with a 6-4-4-6 wheel arraignment, she was powered by four huge 22" cylinders with a 26" stroke and a steam pressure of 300 pounds per inch to drive her eight 84 inch driving wheels! She was built to travel at speeds of 100 mph+ with a full consist of heavy weight pullman cars. Weighing in at 1,0006,010 lbs, the S1 could more than handle any train! The S1 was so big she could only operate on lines west of Pittsburgh on the flats of Ohio and Indiana were she could really stretch her long legs. Crestline, Ohio was the place that she called home. Rumor had it that she was a bit slippery, but in the hands of a good engineer, she was more than capable of pulling all the Pennsy's named passenger trains west of Pittsburgh. Valuable information was learned with the S1 and that was later incorporated into T1 [link] [link] Sadly the S1 was scrapped by the railroad in 1949. Complicated, difficult to work on and too large to operate over most of the Pennsylvania System helped spell her demise. The S1 was just over the top too much! I guess big isn't always better.
