The D & OCSR connected a new exclusive residential community to downtown Dallas on a right-of-way that was described as "the first elevated railway in the South" even though it ran mostly at ground level in a belt line around Dallas and Oak Cliff. Thomas L Marsalis and John J Armstrong envisioned a full-featured community in a setting that the "promotion certificate" promoted in 1890 as one that "...derives its name from the massive oaks that crown the soft green cliffs and stands about two hundred and fifty feet above and to the southward and westward of the city of Dallas, overlooking the city and the view is carried away over the city proper. Cool and healthful breezes prevail during the entire heated term and there is not a night in the hot months of summer when discomfort is felt from the heat, and sound and refreshing sleep is not possible. To the south and southwest for hundreds of miles stretches level and unobstructed prairie over whose bosom these breezes sweep from the Gulf without infection from any unsalubrious conditions."
Works number was 10026 in Auguast 1889. See Locobase 11584 for information on this Texas street railway.
In every respect a much bigger locomotive than the one delivered just 5 months earlier, this street tank had as short a life on the D & OCSR. In 1893, it was sold to the Texas Midland and operated under the same road number for another 35 years before being scrapped.
