Denver Pacific Railway reaches Denver

The Denver Pacific Railway completed its 106-mile line from Cheyenne, Wyoming, to Denver on June 1, 1870, marking the city's first direct rail link to the Union Pacific transcontinental mainline. Engineered by former Union Pacific surveyor John Evans, the route overcame challenging High Plains terrain using lightweight iron rails and modest grades. This connection transformed Denver from an isolated mining camp into a major distribution hub, spurring real-estate booms and the later arrival of the Kansas Pacific. The inaugural train, pulled by a 4-4-0 locomotive named 'The Denver,' carried civic leaders and freight that included mining machinery, symbolizing the shift from wagon trains to steel rails.
