Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 66. See Locobase 16366 for a skeptical 1877 view of steam dummies and Locobase 11577 for a supporting 1889 discussion of the problems associated with running steam dummies on urban street railways. Works number was 9903 in March 1889.
The Mengels operated a variety of furniture factories throughout the upper South. In Louisville, they specialized in mahogany products. According to Connelly's Baldwin production list, the Mengels apparently put the A W Wright to work on the Trimble & Kenton railway, most likely a street railway that ran in those two Kentucky counties. The towns Trimble and Kenton lay 10 miles (16 km) apart.
That didn't last as the 1 moved to A M Stevens Lumber Company through an extra order dated 31 July 1894. It was now named H P Roberts. By 1907, the 1 had returned to the Mengel fold, now working in the Mengelwood complex.
