Placed on rollers without its tender, it was tested on the traction dynamometer to measure its performance, which included maximum drawbar horsepower.

The 60000 was run in tandem with the CB&Q's own M2-A Class 2-10-2 number 6157, in order to compare coal and water consumption.

[6] In the summer and fall of 1927, the 60000 was sent to the Southern Pacific Railroad, which overhauled the locomotive and converted it to an oil burner at its Sacramento Shops.

Following its conversion, the 60000 was tested in both freight and passenger service on the Sacramento Division, during which the engine carried a Southern Pacific tender.

Following tests on the SP, the 60000 was sent to the Great Northern Railway between Everett, Washington and Minot, North Dakota.

[6] Converted back to coal, the 60000 was then returned to the Baldwin Locomotive Works and used as a stationary boiler before being donated to the Franklin Institute.
