Norm Cohen, in "The Long Steel Rail," pp. 406-412, has several versions, which be heads with Kansas City Railroad Blues/KC Moan. He says it "is an example of a railroad song that has close relatives among steamboat songs; it is impossible to say at present whether one form grew out of the other, or if the two developed simultaneously."
The two forms of transport co-existed for a long time.

In the thread on coonjine songs, another is discussed where the same problem exists.
