Train Simulator Tutorial Instroduction to the Turbine – UP 8500 HP Gas Turbine – Sherman Hill

Racing Wheel : Thrustmaster T500RS + Shift TH8R ++++++++++ +Union Pacific operated the largest fleet of gas turbine-electric locomotives (GTELs) of any railroad in the world. The prototype, UP 50 was the first in a series built by General Electric, marketed by the Alco-GE partnership until 1953, for Union Pacific’s long-haul cargo services. The prototype was introduced in 1948 and was followed by three series of production locomotives. At one point Union Pacific said the turbines hauled more than 10% of the railroad’s freight. Fuel economy was poor, the turbine consumed roughly twice as much fuel as an equally powerful diesel engine. This was initially not a problem, because Union Pacific’s turbines were fueled by Bunker C heavy fuel oil. This highly viscous fuel was less expensive than diesel, but difficult to handle. When cold, its consistency is similar to tar or molasses. To solve this problem, a heater was built into the fuel tanks (and later into fuel tenders) to heat the fuel to 200 °F (93 °C) before being fed into the turbine. Eventually UP switched from Bunker C to modified No. 6 heavy fuel oil, which contained fewer pollutants and solvents. Soot buildup and blade erosion caused by corrosive ash plagued all of the turbines. Changes to the air intake systems on the production turbine locomotives improved the air quality reaching the turbine which in turn reduced the wear to the turbine blades and increased the overall running life of the turbine. They were operated into late 1969 and the final two . were stored at the Cheyenne roundhouse in operating condition until being retired in Feb 1970. Union Pacific had long sought the biggest and best locomotives. In the 1930s a pair of steam turbine locomotives were tried but rejected. Before World War II, Union Pacific had been adding diesels to its roster, but none pulled road freight trains. The idea of using four diesels to equal the power of a steam locomotive was unappealing, so the search began for something bigger. General Electric had been building gas turbines for aircraft and proposed using something similar on a locomotive. Union Pacific thought maintenance costs for a locomotive were largely independent of its power, so a smaller number of more powerful locomotives would save money. Union Pacific decided the best way for the turbine locomotives to realize their potential would be to put them on mainline freight trains. The long runs and relatively high speeds would maximize the turbines’ efficiency. After Union Pacific expressed interest, GE built a prototype, GE 101, completed in November 1948. After tests in the Northeast during June 1949, it was renumbered UP 50. Painted in Union Pacific Armour Yellow, UP 50 began a round of tests. Union Pacific never took ownership of this locomotive, however. This was one of the few internal combustion locomotives in North America that had a cab at each end. The cabs themselves resembled the FA units being built by Alco-GE at that time. The sides of the locomotive had numerous air intake louvers that could be opened and closed in varying patterns. UP 50 was a carbody unit with a B+B-B+B wheel arrangement – four two-axle trucks, with pairs connected by span bolsters. The turbine produced 4,800 hp (3.6 MW), of which 4,500 hp (3.4 MW) was available for traction. This power output was more than double that of diesel-electric units of that era. ++++++++++ Best Network wins more money with your youtube channel CPM of $ 3 to $ 30, and in my channel I’ve seen higher of $ 30 per 1000 views 🙂 and pays 70% more than other networks Las mejores Network Gana Mas dinero con tu canal de youtube CPM de $ 3 a $ 30, y en mi canal lo he visto mas alto de $ 30 por cada 1000 vistas 🙂 y paga 70% mas que en otras networks 1st) Zoomin.TV 70%: Of the five networks Zoomin.TV is the best CPM Very high 1º) Zoomin.TV 70%: De las cinco networks Zoomin.TV es la mejor CPM Muy altos 2st) Scalelab 70%: I readily accept 2ª) Scalelab : Te aceptan con facilidad 3nd) GT Channel 70%: You accept easily 3ª) GT Channel : Te aceptan con facilidad 4rd) Freedom 60%: You accept easily 4ª) Freedom : Te aceptan con facilidad 5th) Recstudios 70%: You have to have 200 daily views on your channel for you to accept 5ª) Recstudios : Tienes que tener 200 vistas diarias en tu canal para que te acepten +++++++++++ Give Like and comment on video costs nothing, and yet it does not seem, is helpful;) and not forget subscribe THANK YOU!
