I took this shot of a steam locomotive on my recent visit to South Park City, a re-creation of an early Colorado mining town. This locomotive, painted to represent an engine of the Denver, South Park and Pacific Railroad (D.S.P.&P.R.R.), is a survivor of the era of the “Narrow Guage” railroads. In Colorado we hear about narrow guage all the time, but for those of you not familiar with narrow guage, this refers to the distance between the rails of a railroad track. Standard guage is 4 foot, eight and 1/2 inches between the rails’ inside edges, where the width of a narrow guage track might be 3 foot or less. The narrower guage allowed the train to make sharper turns, necessary in the mountains where digging railroad grades was enormously expensive. The depot’s large red tank in the background held water to fill the steam locomotive’s boiler; and the black car immediately behind the engine held wood or coal for keeping the engine’s fire box fed.
