8.500 Caballos y 1,2 M en Combustible: Las Locomotoras Más Potentes de UP Que Se Arruinaron Solas

In 1950, Union Pacific built the most powerful gas turbine locomotives ever made: the "Big Blow," generating an astonishing 8,500 horsepower—nearly twice that of conventional diesel locomotives. They could effortlessly pull 10,000-ton trains at 75 mph (120 km/h) through the Rocky Mountains. They were absolute technological marvels, utilizing surplus World War II aircraft turbines. But there was a catastrophic problem: they consumed bunker fuel (heavy residual fuel oil) so voraciously that a single locomotive burned through $1.2 million worth of fuel annually (equivalent to $15 million today). The most powerful locomotives in history financially ruined themselves. In this video, you'll discover the story of Union Pacific's Big Blow gas turbines. You'll learn about the impressive specifications: a General Electric turbine derived from B-29 jet engines, generating 8,500 continuous HP versus the 3,500-4,000 HP of contemporary EMD diesels, and a top speed of 145 km/h while hauling loads that would have made conventional diesels struggle. I'll explain why they were economically unviable despite their technical superiority: gas turbines consume fuel proportionally to RPM (revolutions per minute) regardless of load, meaning that the Big Blow burned massive amounts of fuel even at idle or under light load (vs. diesel, which adjusts consumption on demand). Each Big Blow consumed 1,200+ gallons (4,500+ liters) of bunker fuel PER HOUR of operation, and with typical 3,000-4,000 operating hours per year, this meant 3.6-4.8 million gallons annually per locomotive. Furthermore, you will learn about the disastrous economic context: in 1950, when they were built, bunker fuel (oil refining residue) cost a mere $0.10 per gallon, making them viable. However, the 1973 oil crisis drove bunker fuel prices to over $0.80 per gallon, causing each Big Blow to lose massive amounts of money on every trip. While EMD diesels consumed 25-30 gallons per hour, Big Blows consumed over 1,200 gallons per hour—a 40-50x difference in fuel consumption. You will also learn how Union Pacific operated 55 Big Blows between 1952 and 1970. All were retired and scrapped in the 1970s when fuel costs rendered them completely economically unviable. And you will discover the irony that the most powerful locomotives ever built were destroyed not by technical obsolescence, but by their own insatiable appetite for fuel. 🚂 In this video you'll discover: Big Blow Up: 8,500 HP vs. 3,500-4,000 diesel, the most powerful ever GE turbines derived from the B-29, 145 km/h pulling 10,000 tons 1,200+ gallons/hour fuel consumption vs. 25-30 diesel: 40-50x more 3,000-4,000 hours/year: 3.6-4.8 million gallons annually 1950: bunker fuel $0.10/gallon viable, 1973: $0.80+ unviable 55 operated 1952-1970, all scrapped due to fuel costs 💸 When absolute power is absolute economic ruin 👍 LIKE if Big Blow is the most fascinating/tragic locomotive 💬 COMMENT if you would operate an 8,500 HP turbine knowing the costs 🔔 SUBSCRIBE for more tech that financially self-destructed #BigBlowUnionPacific #8500Horses #TheyRuinedThemselves
