This is an interesting location, by the date of this photo, it is the property of the Chicago River & Indiana Railroad, a subsidiary of the New York Central Railroad. From the beginning of the 20th Century, this had been the property of the Chicago Junction Railway (a company formed by merging the Chicago and Indiana State Line, and Chicago, Hammond and Western on April 26, 1898) to form the Chicago Junction Railway, with the Union Stock Yard & Transit Company of Chicago (USY&T) as the parent company, and although the CJ owned but 2.185 miles of track, it appears that it was the last two miles into the Chicago Union Stock Yards, so if your intention was to get livestock delivered to the stockyards, you had to deal with the CJ (NYC). On May 19, 1922, the New York Central Railroad bought control of the Chicago River and Indiana Railroad (CR&I) and simultaneously leased the Chicago Junction to the CR&I. On August 26, 1958, the CR&I acquired the property of the Chicago Junction and lessor USY&T, and in 1976 the Conrail acquired the CR&I's lines.
