space was refurbished, and the theater was restored. The entrance to the train concourse was renovated into the Omnimax theater, and the men's lounge became Amtrak's waiting room and ticket counter. In 1986, the Union Terminal Association (UTA) was created to facilitate long-term preservation of the terminal. The organization included community members and city and county officials. The UTA leased the building from the city and searched for tenants. The UTA joined the Historical Society and Museum of Natural History in creating the Heritage Center at Union Terminal. The first exhibit shown in the terminal was U.S.S.R.: Individual, Family, Society in February 1988, in a cultural agreement between US President Ronald Reagan and Soviet leader Mikhail Gorbachev. The museum as a whole opened on November 10, 1990, though it had its "grand opening day" on November 2, 1991, with the two museum's first permanent exhibits there. The original members of the museum center were the Cincinnati Historical Society Library, Cincinnati History Museum, Cincinnati Museum of Natural History, and the Robert D. Lindner Family Omnimax Theater. The museum center opened with the largest display of robotic dinosaurs, the largest World War II commemorative exhibit, and one of fourteen Omnimax theaters in the United States. Museum center officials were unsure if people would travel to the new museums as predicted, though the center became the fourth-largest attraction in the area, behind the Cincinnati Reds, Kings Island, and the Cincinnati Zoo. The renovations included the installation of the Grand E.M. Skinner Concert Organ. In 1995, the entities officially merged to create the Cincinnati Museum Center, also joined by the Cinergy Children's Museum in October 1998. In 2004, the county again approved an operating levy for the building's operating costs and capital repairs. In 2009, the museum center began a project to restore the southwest wing of the terminal, including new roofing, masonry repairs, a new HVAC system, and restoration of four dining rooms on the south side of the terminal. In 2009, county residents approved an extension of the 2004 levy for further repairs. From July 2016 until November 2018, the museum was shut down in order to complete a $228 million renovation throughout the entire building, in addition to restoring numerous rooms original to the building. The renovation was approved by Hamilton County voters through an increased sales tax, bringing $176 million, and was also funded by $5 million in state grants,
