This is an economic and social history of the Texas Electric Railway, which operated three interurban lines branching out of Dallas. The railway operated from 1917 until 1948, although the company was not dissolved until 1955. Of necessity, the study is based on primary source materials, including railway pamphlets, trade journals such as the Electric Rai Journal, personal interviews, Texas and United States Government documents and publications, and newspapers. Unfortunately, original financial records of the company no longer exist; therefore, financial information comes from Moody's Manual of Investments, Public Utilities.
