Information: - A gas turbine - electric locomotive, or GTEL, is a locomotive that uses a gas turbine to drive an electric generator or alternator. The electric current thus produced is used to power traction motors. This type of locomotive was first experimented with during the Second World War, but reached its peak in the 1950s to 1960s. Few locomotives use this system today. - The University of Aberdeen is a public research university in the city of Aberdeen, Scotland. It is an ancient university founded in 1495 when William Elphinstone, Bishop of Aberdeen, petitioned Pope Alexander VI on behalf of James IV, King of Scots to establish King's College, making it Scotland's third-oldest university and the fifth-oldest in the English-speaking world. The university as it is today was formed in 1860 by a merger between King's College and Marischal College, a second university founded in 1593 as a Protestant alternative to the former. Today, Aberdeen is consistently ranked among the top 200 universities in the world and is one of two universities in the city, the other being the Robert Gordon University. - Robert Davidson ( 1804 -- 1894 ) was a Scottish inventor who built the first known electric locomotive in 1837 . He was a lifelong resident of Aberdeen , northeast Scotland , where he was a prosperous chemist and dyer , amongst other ventures . Davidson was educated at Marischal College , where he studied for one year on a scholarship - he had an education in return for being a lab assistant . He became interested in the new electrical technologies of the day . From 1837 , he made small electric motors on his own principles , though William H. Taylor in the US made similar motors from 1838 . Both men worked independently without knowledge of the other 's work . - Marischal College is a large granite building on Broad Street in the centre of Aberdeen in north-east Scotland, and since 2011 has acted as the headquarters of Aberdeen City Council. However, the building was constructed for and is on long-term lease from the University of Aberdeen, which still uses parts of the building to house a museum and for ceremonial events. Today, it provides corporate office space and public access to council services, adjacent to the Town House, the city's historic seat of local government. Many Aberdonians consider Marischal College to be an icon of the "Granite City" and to symbolise the zenith of Aberdeen's granite-working industry. - An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or fuel cell. Electric locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric locomotives because the electric generator/motor combination serves only as a power transmission system. Electricity is used to eliminate smoke and take advantage of the high efficiency of electric motors, but the cost of electrification means that usually only heavily used lines can be electrified.
