Context paragraphs:
Cincinnati, Indianapolis and Western Railroad: The Cincinnati, Indianapolis and Western Railroad (reporting mark CIWN) was established in 1915 as a reorganization of the Cincinnati, Indianapolis and Western Railway, which in turn had been created in 1902 as a merger of the Indiana, Decatur and Western Railway (ID&W) and the Cincinnati, Hamilton and Indianapolis Railroad (CH&I).  Predecessors of the ID&W include the Indianapolis, Decatur and Western Railway (1888-1894), the Indianapolis & Wabash Railway (1887-1888), the Indianapolis, Decatur and Springfield Railway (1875-1887), and the Indiana and Illinois Central Railway (1853-1875).

Howard Van Doren Shaw: Howard Van Doren Shaw AIA (May 7, 1869 – May 7, 1926) was an American architect.  He became one of the best-known architects of his generation in the Chicago, Illinois area.  Shaw was considered a leader in the American Craftsman movement, best exemplified in his 1900 remodel of Second Presbyterian Church in Chicago.  He designed Marktown, Clayton Mark's planned worker community in Northwest Indiana.

Marktown: Marktown is an urban planned worker community in East Chicago, Indiana, United States, built during the Progressive Era in 1917 from marshland to provide a complete community for workers at The Mark Manufacturing Company.

Indiana Jones (franchise): Indiana Jones is an American media franchise based on the adventures of Dr. Henry Walton "Indiana" Jones, Jr., a fictional tenured professor of archaeology.  It began in 1981 with the film "Raiders of the Lost Ark".  A prequel, "Indiana Jones and the Temple of Doom", followed in 1984, and a sequel, "Indiana Jones and the Last Crusade", was released in 1989.  A fourth film, "Indiana Jones and the Kingdom of the Crystal Skull", was released in 2008, and was the last in the series to be distributed by Paramount Pictures.  The series was created by George Lucas; the films star Harrison Ford and are directed by Steven Spielberg.  The Walt Disney Company has owned the "Indiana Jones" intellectual property since its acquisition of Lucasfilm, the series' production company, in 2012. A fifth film is planned for release on July 10, 2020, with both Spielberg and Ford returning.

Clayton Mark: Clayton Mark (June 30, 1858 – July 7, 1936), one of the pioneer makers of steel pipe in the United States, was an industrialist in the Chicago area who founded the Mark Manufacturing Company in 1888, a firm for the fabrication and sale of water-well supplies and Clayton Mark and Company in 1900.  In addition, Mark founded Marktown, a planned worker community in Northwest Indiana on the National Register of Historic Places.  He was known for his philanthropy and civic contributions.

Chicago, Indiana and Southern Railroad: The Chicago, Indiana and Southern Railroad (reporting mark CI&S) is a defunct railroad which operated in the states of Illinois and Indiana during the early 20th century.  The CI&S formed in 1906 from the consolidation of the two other railroads: the Indiana, Illinois and Iowa Railroad and the Indiana Harbor Railroad.  The new railroad also owned the capital stock of the Danville and Indiana Harbor Railroad.  The stock of the new company itself was wholly owned by the Lake Shore and Michigan Southern Railway and the Michigan Central Railroad, both of which were part of the New York Central system.  A 1907 report called the CI&S a "tributary to the Lake Shore."  The railroad operated two lines: a north-south line between Indiana Harbor (East Chicago, Indiana) and Danville, Illinois, and a line from the Spring Valley coalfields at Seatonville, Illinois, to South Bend, Indiana.  Together the two lines controlled 301 mi of track.  In 1914 the CI&S was one of several railroads consolidated to form the modern New York Central Railroad.

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.

Indiana and Ohio Railway: The Indiana and Ohio Railway (reporting mark IORY) is an American railroad that operates 570 mi of track in Ohio, southern Michigan, and parts of southeastern Indiana.  It is owned and operated by Genesee & Wyoming, who acquired the railroad in the 2012 purchase of RailAmerica.  The Indiana and Ohio Railroad (reporting mark INOH) (merged into the IORY in 1997) was formed in 1978 to operate a branch between Valley Junction, Ohio and Brookville, Indiana.  The IORY's original line, acquired in 1985, connected Mason and Monroe, Ohio.  The IORY set up a tourist operation known as the Indiana and Ohio Scenic Railway which operated over this line.  The tourist train still operates out of Lebanon, Ohio under the ownership of the Cincinnati Railway Company (CRC) under the name Lebanon Mason Monroe Railroad.  Another line, acquired in 1986, runs from Norwood to Brecon, Ohio.  In 1991, the former DT&I between Washington Court House, Ohio and Springfield, Ohio came into the system via a designated operator agreement with the West Central Ohio Port Authority.  The system expanded north into Michigan in 1997 when it acquired the remainder of the former DT&I mainline between Diann, Michigan and Springfield, Ohio.  In 1994, it acquired two lines from Conrail in Springfield, Ohio: one between Springfield and Bellefontaine; and one between Springfield and Mechanicsburg.  The Indiana and Ohio Central Railroad (reporting mark IOCR) was the designated owner of these two lines until 2004.  One of the I&O's major events took place in 1996 when it was acquired by RailTex.  In 2000 RailTex was absorbed by RailAmerica and in 2004 the I&O absorbed the Indiana and Ohio Central Railroad.  Genesee & Wyoming acquired RailAmerica in December 2012.

William Bell Riley: William Bell Riley (March 22, 1861 in Greene County, Indiana, USA – December 5, 1947 in Golden Valley, Minnesota) was known as "The Grand Old Man of Fundamentalism."  After being educated at normal school in Valparaiso, Indiana, Riley received his teacher's certificate.  After teaching in county schools, he attended college in Hanover, Indiana, where he received an A.B. degree in 1885.  In 1888 he graduated from the Southern Baptist Theological Seminary in Louisville, Kentucky.  In 1908, the Southwestern Baptist University of Jackson, Tennessee, conferred upon Riley an honorary D.D. degree.  He served several Baptist churches in Kentucky, Indiana, and Illinois before taking the pastorate at the First Baptist Church in Minneapolis, Minnesota in 1897.
