17-car train over a distance of 48 kilometers (level track) at a speed of between Fort Wayne and Chicago. Engineer Mr. Flaya Cartwright and Fireman Mr. M.E. Brown were assigned to this official test run. E.S. Cox, a British locomotive engineer, once traveled on the footplate and reported that "100mph was maintained and exceeded for 12 consecutive minutes". While economical at speed, the locomotive was highly-uneconomical at lower speed. The turbine used less steam than conventional locomotives above , but below that the locomotive used too much steam and fuel. The boiler normally operated at , but at low speed the pressure could drop as low as . The increased fuel usage at low speeds caused the firebox to run hotter, which sometimes caused stay bolts to break. The locomotive's problems, the rapid decline of PRR's ridership since 1947 and the advantages of the emerging diesel locomotive ensured that #6200 would never be duplicated, but S2 still participated in the 1948 Chicago Railroad Fair with a T1 4-4-4-4 Duplex Steam Locomotive. In August 1949, the locomotive suffered severe turbine damage. Since the maintenance costs rose steadily, the S2 was finally stored in Crestline and Altoona. In 1952, she was finally retired and was scrapped the following year. Service history The S2 was assigned to the Fort Wayne Division and based at the Crestline enginehouse. It hauled various prestigious passenger trains serving the New York to Chicago corridor such as The Broadway Limited, The Liberty Limited, The Trail Blazer, The General, The Manhattan Limited and The Golden Arrow on the route between Chicago and Crestline, Ohio (283 miles/ 446 km). S2 also hauled troop trains and was seen towing express freight trains. PRR S2 #6200, as an experimental prototype of a direct-drive steam turbine locomotive, ran 103,000 miles in total before it was completely withdrawn from service in August, 1949 and would soon await the scrapper's torch. The 6200 was eventually scrapped in Conway, Pennsylvania. In popular culture The model train company Lionel made several models of the S2. The first ones, 671 and 2020, were released in 1946 and were discontinued in 1949. The 681 turbine's first production run was in 1950 and 1951. It was similar to both of the original turbine models but the 681 has Lionel's Magne-Traction feature which makes the wheels magnetic. In 1952, The Korean War caused a shortage of magnetic material, so the 671
