It also reflects local and western railroading history, including competition among railroads and the line that gave Los Angeles its fourth transcontinental connection.","narrative":"This two-story railroad depot at 3751 Vine Street in Riverside was built in 1904 by the San Pedro, Los Angeles & Salt Lake Railroad. It is a wood-framed Mission Style building with dashed stucco over metal lath, a red clay tile roof, four towers with pyramidal tile caps, and curved parapet walls over the gable ends. Unlike many Mission Style buildings of its era, it omits applied decorative plaster relief, making it a plain, simplified version of the style. The only major exterior change was the 1943 enclosure of the open north waiting porch. The depot is valued chiefly for its design, which served as a model for other stations on the line to Nevada and for depots in Ontario and Pomona. It also illustrates the story of the Salt Lake line, its rivalry with Southern Pacific, and the route that gave Los Angeles its fourth transcontinental railroad. Union Pacific took over the route in 1921.","period_of_significance":"1900-","architect_builder":"S.P.L.A. & S.L.R.R.","architectural_style":"Mission Style","criteria":[],"status_note":"Listed as unoccupied and not in use; the north waiting porch was enclosed in 1943.
