| The locomotive was built in June 1946 as Illinois Central 9027, and was renumbered 612 in October 1953. The railroad extensively rebuilt the locomotive in October 1968, replacing its 6-cylinder 600-horsepower prime mover with an 8-cylinder 1,000-horsepower one, and renumbered it 13. It was to be the prototype for the rebuilding of the IC's entire fleet of SW1's, which would have been renumbered 1-17; but it was the only one done. The 13 was photographed at Mays Yard, and it spent much of its later life in the New Orleans area. It was retired in 1988. |
