Drury (1993) shows that this one locomotive originated on the New York, Chicago & St Louis in 1923. That's what the diagram shows as well and that document shows the engine specifically assigned to the Toledo, St Louis & Western, which had been acquired that same year. Its withdrawal in 1934, taken with Drury's comment that Clover Leaf trackage was of such light construction that few Nickel Plate locomotives could operate on it, suggests to Locobase that this was a trimmed-down version of a standard NKP Consolidation. The superheater was removed, LB guesses, to reduce the axle loading.
