This small class lasted only a few years after the Clover Leaf's absorption into the Nickel Plate. Retirements came in 1927 and 1929.
These Clover Leaf Ten-wheelers stood on relatively tall drivers. Sometime after their purchase, the class was superheated and it's that manifestation that shows in the specs. After their absorption into the Nickel Plate, the class was retired in 19301-1933.
