St. Louis station (CTA Garfield Park branch)

It was constructed by the Metropolitan West Side Elevated Railroad and served its Garfield Park branch.

The Metropolitan West Side Elevated Railroad Company was granted a 50-year franchise by the Chicago City Council on April 7, 1892,[1] and began securing right of way shortly thereafter.

[2] As designed, the Metropolitan's operations comprised a main line that went westward from downtown to diverge into three branches – one northwest to Logan Square, one due west to Garfield Park, and one southwest to Douglas Park – and serve various parts of Chicago's west side.

[3][5] The expenses incurred in constructing the Metropolitan's vast trackage would catch up to the company, which entered receivership in 1897; the similarly named Metropolitan West Side Elevated Railway Company was organized in January 1899 and assumed operations on February 3 of that year.

[6] The interurban Aurora Elgin and Chicago Railway (AE&C) opened in 1902 and began using the Garfield Park branch in 1905.
