Union Tank Car Company or UTLX (their best known reporting mark) is a railway equipment leasing company (and car maintenance / manufacturing) headquartered in metro Chicago, Illinois. As the name says, they specialise in tank cars, and covered hopper cars. As of September 2005, according to their site, they have about 80,000 cars in their fleet. Union Tank Car Company was founded in 1866 by Captain Jacob J. Vandergrift, in response to the economic activities of John D. Rockefeller in the years leading up to his creation of Standard Oil. Vandergrift was involved in the conflicts in the oil regions of Western Pennsylvania in the 1860s–1870s. Eventually, Union Tank Car Company and Vandergrifts other holdings, which included pipeline and riverboat transport companies, merged with the company that later became Standard Oil. Rockefeller, once Captain Vandergrifts nemesis, made him Vice President of Standard Oil. The town of Vandergrift, Pennsylvania, built in 1895 by steel company president George G. McMurtry to house his workers, was named in Vandergrifts honor. TransUnion was formed as a holding company in 1968 to hold Union Tank Car Company. TransUnion soon began acquiring credit information and information management companies as a second major investment. The Marmon Group acquired TransUnion in 1981, spinning off the TransUnion name and the financial portion of the holding company to Madison Dearborn Partners in the 1990s.
