Nickel Plate 2-8-4 No. 758 leads a double-header with No. 754 through Fostoria, Ohio. This postcard view, courtesy of Gary Thompson, comes from 1958, near the end of steam on the NKP. The photographer is unknown. These class S-2 Berkshires were capable of moving heavy freight over the Midwestern plains at a respectable speed. It is likely, then, that the reason for double-heading was not an extra-heavy train but the need to return one of the locomotives to a terminal to address a power imbalance.
