Context paragraphs:
Indiana Railroad: The Indiana Railroad (IR) was the last of the typical Midwestern United States interurban lines.  It was formed in 1930-31 by combining the operations of the five major interurban systems in central Indiana into one entity.  The predecessor companies came under the control of Midland Utilities, owned by Samuel Insull.  It was Insull's plan to transform the Indiana interurban network into a new Indiana Railroad by modernizing the profitable routes and abandoning the unprofitable ones.  With the onset of the Great Depression, the Insull empire collapsed and the Indiana Railroad was left with a decaying infrastructure and little hope for overcoming the growing competition of the automobile for passenger business and the truck for freight business.  The IR faced bankruptcy in 1933, and receiver Bowman Elder was designated to run the company.  Payments on bonded debt were suspended.  Elder was able to keep the system virtually intact for four years, and IR operated about 600 mi of interurban lines throughout Indiana during this period.  During the late 1930s, the routes were abandoned one by one until a 1941 wreck with fatalities south of Indianapolis put an abrupt end to the last operation of interurbans in Indiana.
