English: Original caption: "Fig. 8 -- Goodman 80-h.p. Rack Rail Locomotive Pulling 25-ton Trip Up 16 Per Cent Grade -- No. 11 Mine." This mine was located north of Marysville, Iowa and west of Bussey, Iowa. The locomotive uses the Morgan Rack combined third-rail and rack-traction system, and runs on 250-volt DC power at 80 horsepower on 36-inch gauge track. The man on the right is driving the locomotive; the other two men are standing behind it. This photograph was widely used in later Goodman Manufacturing Company advertising and it was used as a stock photo in articles about their mining machines. |

| Foinse | E. C. DeWolfe, Operations of Mammoth Vein Coal Co., Bussey, Iowa, The Black Diamond, Vol 37, No. 5 (Aug. 4, 1906); page 30. A higher resolution but higher contrast version appears in Leonard. V. Newton, Electric Locomotive Haulage In and About Mines, B.S. Thesis, Mining Engineering, U. of Illinois, 1913; Plate 41. These images have been combined here. Later in 1906, Goodman made extensive use of this photo in their advertising; see, for example, Black Diamond, Vol. 37, No. 21 (Nov 21, 1906); page 50 and Black Diamond, Vol. 37, No. 22 (Dec 1, 1906); page 50. This photo also appears in Electricity in Mining. the Electrical Record, Vol. II, No. 4 (Oct. 1907), page 16, and as Figure 64 in E.B. Wilson, Evolution of Mine Haulage, Mines and Minerals (Sept. 1910) Vol. 31, No. 2; page 82. |

Geolocation inferred from mine map Figure 6 of The Black Diamond article, noting that the caption on that figure is wrong and the text makes it clear that it is a map of mine number 11. The mine location itself comes from the map in Coal Mines in Marion County and index entry 63145 for Empire Mine No. 11 -- the outline and location of which fit the map and description in the Black Diamond text. Note that History of Marion County indicates that the Mammoth Vein Coal Company mines were later operated by the Empire Coal Company. This geolocation here is probably good to a few hundred feet despite the fact that the mine is deep underground and the entrance is obliterated by a highway and strip mining.
