An electro-diesel locomotive is powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a specific purpose. Electro-diesel locomotives are used to provide continuous journeys along routes that are only electrified without a change of locomotive, avoid extensive running of diesel under the wires, giving solution where diesel engines are banned, they may be designed or adapted for electric use for diesel use or to work well as either electric or diesel. Note that, as well as the electric multiple unit and diesel multiple unit, where no discrete locomotive is present electro-diesel multiple units exist; this is an electric locomotive with a small auxiliary diesel prime mover intended only for low-speed or short-distance operation. Some of these, such as the British Rail Class 74, were converted from electric locomotives; the Southern Region of British Railways used these locomotives to cross non-electrified gaps and to haul boat trains that used tramways at the ports of Southampton and Weymouth.
For economy, the diesel engine and its generator are smaller than the electric capacity. The Southern types were of 1,600 hp or'Type 3' rating as electrics, but only 600 hp as diesels. Classes had as much as 2,500 hp on electric power, but still the same diesel engines. Despite this large difference, their comparable tractive efforts were much closer and so they could start and work heavy trains as diesels, but not to the same speeds; this is a diesel locomotive with auxiliary electric motors operating from 750 V DC third rail where non-electric traction is banned. The primary function for these models is to provide a "one-seat ride" between the electrified and non-electrified sections of a rail system or to allow trains to run through tunnels or other segments of track where diesel locomotives are prohibited due to their production of exhaust. Once out of the tunnels, the engines are started and operation is as a normal diesel locomotive. With modern electronics, it is much easier to construct an electro-diesel locomotive or multiple-unit, at home running at high speeds both "under the wires" and under diesel power.
These will operate under pure electric traction where possible, use the diesel engines to extend the journeys along non-electrified sections which would not be cost effective to electrify. They may be used on long cross-country routes to take advantage of shorter sections of electrified main lines. Gmeinder class 478.6 diesel and 750 V DC third-rail.

Gama Marathon was first presented in 2012 at InnoTrans Berlin; the locomotive underwent a series of tests with rail operators Lotos Kolej and PKP Intercity, after successful conclusion it was offered on the market. In July 2015 the Polish train-operating company Locomotiv bought the prototype and signed order for further two Marathons.

An experimental electro-diesel locomotive, DEL120, was built by London Underground in 1940 but was not a success. Two types have been built. British Rail Class 73, dating from 1962 – the more successful design, with some still in regular use, they had lower power output in the diesel mode, but are being re-engined to provide more po
Young Women's Preparatory Academy is a grade 6-12 magnet school for girls, located in the Little Havana neighborhood of Miami, Florida. It is a part of Miami-Dade County Public Schools. YWPA was the first public school established in South Florida, only for girls; the school was established in 2006, with a focus on mathematics and technology. It had about 400 students as of 2012, as of 2014 had about the same number; as of 2015 Concepción I. Martinez is the principal. Young Women's Preparatory Academy is a selective public secondary school in Miami, Fl, admitting less than 10% of applicants for the fall semester of 2011. Albeit the school's main track specializes in mathematics and sciences, the small class sizes allows for there to be more focus on the needs of each individual student, allowing counselors to structure a program that will help each student learn and gather experience in line with their goals past secondary school. A strength in Young Women's Preparatory Academy lies in the accessibility of the faculty members and the passion that all of the professors convey in their work.
Professors are known for constructing a rigorous course curriculum, their accessibility and empathy for their students allows the opportunity for students to gather knowledge in an area at a depth beyond what their peers outside of the school would be receiving. Mathematics and language arts in Young Women's Preparatory Academy are advanced, a year ahead of all other public school in MDCPS. All subjects are taught with a multi-disciplinary approach, allowing for students to develop a context for the material they are learning. Circa 2012, U. S. News & World Report ranked YWPA # 2 in Florida; as of that year, 300 girls were on the school's waiting list. In 2013, YWPA won a Magnet Schools of Excellence Award from the Magnet Schools of America. Teachers and administrators at YWPA have attributed the school's success to its lack of boys.

The Human Jungle is a British TV series about a psychiatrist, made for ABC Television by the small production company, Independent Artists, for transmission on ITV. Starring Herbert Lom and Sally Smith, it ran for two series, which were first transmitted during 1963 and 1965; the majority of the episodes each focused on one patient, whose psychological ailment Dr Corder would treat using a humane yet idiosyncratic approach that mixed Freudian psychoanalysis with the contemporary methods associated with the then-fashionable theories of R. D. Laing. Several psychiatric techniques, such as word association, group work, role-play and hypnotherapy, were featured in the series; because of the demands of the 50-minute television episode, it was suggested that Corder would continue to see his patient after the denouement. Corder's initial patient in a story would turn out not to be the character with the pressing mental health issue. Herbert Lom as Dr Roger Corder M. D. D. P. M, who sees patients in his consulting room at 162 Harley Street and at the local St Damian's Hospital Michael Johnson as Dr Jimmy Davis, junior colleague Sally Smith as Corder's headstrong teenage daughter Jennifer, whose mother, we are told, was killed in a car accident Mary Yeomans as his secretary, Nancy Hamilton Mary Steele as his personal assistant, Jane Harris The series was created by Ronald J. Kahn, credited on screen as'assistant to the producers', produced by Julian Wintle and Leslie Parkyn.
The theme music was composed by Bernard Ebbinghouse, arranged and recorded by John Barry and his Orchestra. A number of high-profile guest stars appeared in his surgery or as hospital patients, including Joan Collins, Margaret Lockwood, Flora Robson, Roger Livesey, Rita Tushingham and André Morell; the first series was filmed at Beaconsfield Studios, which closed down shortly after production ended. The script editor was John Kruse; the advisor on psychiatric content was Dr Hugh L. Freeman, on behalf of the National Association for Mental Health. Airdate is for ABC Weekend Television. ITV regions varied order. Episode order is given as per Network DVD. Airdate is for Associated-Rediffusion. ITV regions varied order. ABC Weekend Television was broadcast two days later.
