Discussion on “the development of the electric mine locomotive” (Eaton), Pittsburgh, Pa., April 10, 1914. (see proceedings for April, 1914)

W. W. Miller: Referring to Mr. Eaton´s paper, it may be of interest to note that a mine locomotive of 14,000 lb. weight with a single motor chain drive was built in 1886, and installed in the anthracite field. This locomotive was in daily operation until 1909, and although preserved since then for its associations and historical interest, it is still used in the mines whenever required by emergencies.
