Minutes (1897-1970), annual reports (1885-1980), correspondence and subject files (1910s-1970s), payroll records (1885-1970), accounting records (1879-1977), operating statements (1921-1975), engineering and architectural drawings (1889-1954), and miscellaneous legal and financial papers (1896-1955) documenting the existence of a now defunct company organized in 1879 to serve the nine major railroads entering the Twin Cities. The jointly owned and operated company controlled 9.24 miles of St. Paul trackage and terminal facilities, including the depot building. The company was operated in tandem with the Minnesota Transfer Railway Company, with effective control of both properties exercised by the same board comprised of representatives of the nine joint tenants. The current depot facility was built during 1919-1924; passenger service ceased in 1971. The records document most important aspects of the company's management throughout its existence. There is information on its operations, finances, government relations, personnel, and physical plant. An extensive set of linen tracings document the construction and modification of the depot building.
