Great Southern Railroad
The Great Southern Railroad was a 41-mile short-line which interchanged with the Oregon Railway and Navigation Company, later the Oregon–Washington Railroad and Navigation Company (OWR&N), in The Dalles, Oregon, United States.  The rail line ran south along Fifteen Mile Creek through Boyd to Dufur, and on to the small community of Friend.  Besides the railhead junction with OWR&N, the Great Southern also had connections with two steamship line operating on the Columbia River; The Dalles, Portland & Astoria Navigation Co., and The Open River Transportation Co.

The railroad was established by John G. Heimrich, a late 19th Century entrepreneur of German ancestry.  Construction of the railroad was started on April 8, 1904, and was completed on July 1, 1913 with the establishment of regular train service from The Dalles to Friend.  The Great Southern served agricultural and timber interests on the Columbia Plateau south of The Dalles and eastern slopes of Mount Hood.  The general offices for the Great Southern were located in The Dalles, Oregon.  The General Officers of the company, listed in 1925, were as follows:
 President: John G. Heimrich
 Vice-President: Julius L. Meier
 2nd Vice-President: S.A. Hull
 Secretary: George W. Joseph
 Treasurer General: John G. Heimrich
 Manager and Purchasing Agent: John G. Heimrich
 Auditor: A. Froembling

The Great Southern's revenues reached a peak in 1910, but leveled off into the early 1920s.  With the introduction of regular bus service, and an increase in automobile and truck traffic between The Dalles and Dufur, revenues began to decline after 1921.  Regular train service came to an end on January 5, 1928 with the closing of the depots at Dufur and Friend.  Attempts to resurrect the line as The Dalles and Southern failed in 1933.  The line was officially abandoned on September 30, 1935.  Very little of the Great Southern remains to this day. The Dalles depot, which was moved from its original location to its current site at the base of Brewery Grade, is the most visible relic of this short-lived Oregon railroad.
