The Gila Valley, Globe & Northern Railroad erected a Roundhouse and associated shops in late 1899, which were designed by Tucson architect Henry C. Trost before the formation of the firm of Trost & Rust. According to the Associated Press, the building was destroyed by fire on October 6, 1909 (Ref: https://apnews.com/article/a0106d72e90d4177a2bfeac4635ee137). The month that the Roundhouse was announced, (June, 1899), reflects the beginning of a veritable explosion of designs, mostly residential, in the Tucson area from Trost, who had arrived in the area from Colorado the previous month.
Newspaper clipping (screenshot), which was discovered by researchers Lloyd C. and June F. Engelbrecht, is from the 06/10/1899 El Paso Herald. We found the “Tucson Star” article referenced (actually the Arizona Weekly Star, 06/15/1899 page 2) which is an identical paragraph. (Ref: newspapers.com)
