The only megafreighters the Chicago, Indianapolis & Louisville ever bought, these Santa Fes were typical low-drivered drag-freight hogs. As the Monon's fortunes declined in the late 1930s, an excess of freight power led to the sale of 2 of the octet to the Tennessee Railroad (1942 and 1945). The other six were scrapped between 1941 and 1947 as Monon became an early adopter of diesel power.
