790 was saved from scrap and purchased by Lou Keller, and he used it to pull excursion trains in Iowa.

641 pulled heavy freight trains for the IC in Tennessee, and later, in 1918, the locomotive was rebuilt and modified with superheater equipment.

[1] During the 1950s, the IC—having discovered the financial benefits of dieselizing their fleet—was removing their steam locomotives from revenue service, and in doing so, they put Nos.

[3][5] Keller made plans to host steam excursions with the locomotive, but the IC refused to operate it for him.

[3][5][9] This was considered the final commercial freight operation to be performed by an IC steam locomotive.

[3][10][11] By the end of 1965, the operation plans fell through, and de Camp put his locomotive up for sale.

790 was sold again to F. Nelson Blount, who added it to his Steamtown, U.S.A. collection in Bellows Falls, Vermont.

[1][5] The locomotive was eventually moved alongside the rest of the Steamtown collection to Scranton, Pennsylvania.
