Question: Which rolling stock did the Turboliner replace? Passage 1:Cornelia Bonte Sheldon Elgood was born in 1874; her father was a judge in Egypt and her brother was Sir Maurice Amos. She was awarded her M.D. degree by the University of London in 1900 and then was appointed to the International Quarantine Board of Egypt, the first female doctor to be appointed to the board, where she remained until 1902. That year Elgood opened an outpatient clinic for women and children in addition to establishing a private practice. In 1906 she moved to Cairo, Egypt's capital, and married Major Percy Elgood the following year. There she was tasked to develop and expand a program to educate girls by the Ministry of Education. The program was very successful, starting with 600 students in 3 schools, it had 20,000 students in 106 schools by 1923. Elgood also served on the Countess of Cromer's commission to establish the first free children's dispensaries in Egypt in which many Egyptian women were trained as midwives. She also sponsored Egyptian women to study medicine in Britain and served on the board of the Victoria Hospital, Cairo. Elgood remained in Egypt until forced to leave during the Suez Crisis in 1956 and lived in London until her death on 21 November 1960. She was awarded the Order of the Nile in 1921 and the CBE in 1939.
Passage 2:In April 2012, author Kate Bornstein spoke about McDonald on MSNBC cable television program Melissa Harris-Perry, comparing McDonald's situation with George Zimmerman's in the aftermath of the shooting of Trayvon Martin regarding self-defense issues and how the case is viewed through the media focus. The case also attracted national attention from LGBT activists including author Leslie Feinberg, who wrote that "the right of self-defense against all forms of oppressionsthe spirit of Stonewallis at the heart of the demand to free [McDonald]". Cam Gordon, a member of the Minneapolis City Council, announced his support for McDonald and called the incident "another example [of] transgender women of color being targeted for hate- and bias-related violence", and Susan Allen, a member of the Minnesota House of Representatives, called on Freeman to consider the "extenuating circumstances" of McDonald's case. In May 2013, an article by Marc Lamont Hill for Ebony.com entitled "Why Aren't We Fighting for CeCe McDonald?" won the GLAAD Media Award for "Outstanding Digital Journalism Article". McDonald also received the support of transgender activist and actress Laverne Cox, who stars in the television series Orange Is the New Black.
Passage 3:Following its takeover of most passenger rail service in the United States on May 1, 1971, Amtrak retained the Abraham Lincoln as a daily Chicago-St. Louis service, operating in tandem with the GM&O's old Limited. In November of that year Amtrak extended both the Abraham Lincoln and the Limited (now known as the Prairie State) through Chicago to Milwaukee, Wisconsin. In October 1973, Amtrak replaced the rolling stock with the new French-built Turboliner; as part of this change the trains were re-branded as Turboliners and truncated to Chicago. In February 1976 Amtrak returned conventional rolling stock to the route and revived the Abraham Lincoln name along with the Ann Rutledge. Amtrak added the State House to the Chicago-St. Louis corridor in 1977. Also in 1977, Amtrak extended the Abraham Lincoln to Kansas City and renamed it the Ann Rutledgea name that had briefly disappeared from the timetable in 1976-77 when Amtrak extended the Inter-American to Chicago. Today service between Chicago and St. Louis is handled by the "Lincoln Service".
