The Lycoming XR-7755 was the largest piston aircraft engine ever built in the United States, [Note 1] with 36 cylinders totaling about 7,750 in 3 (127 L) of displacement and a power output of 5,000 horsepower (3,700 kilowatts). It was originally intended to be used in the "European bomber" that eventually emerged as the Convair B-36. Only two ...
The EMD DDA40X is a 6,600 hp (4,943 kW) D-D locomotive, built by EMD from 1969 to 1971 exclusively for the Union Pacific Railroad. [1] It is the most powerful diesel–electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. [2]
It is one of three engines for the 777-200 and -200ER, and the exclusive engine of the -200LR, -300ER, and 777F. It was the largest jet engine, [3] until being surpassed in January 2020 by its successor, the 110,000 lbf (490 kN) GE9X, which has a larger fan diameter by 6 inches (15 cm). However, the GE90-115B, the most recent variant of the ...
Airliners are growing ever bigger to haul more people per flight, which means they need appropriately massive engines -- and GE Aviation is happy to oblige. It recently conducted the first test ...
One of the most powerful electric locomotives ever built, it also is the most powerful (short term) single-frame locomotive ever built (currently [when?] its maximum short term power is limited to 9,000 kilowatts (12,069 hp) [8]); It has immense short term power with a tractive effort of 312 kN up to a speed of 140 km/h (87 mph). DB Class 151
In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

The long-awaited 777X, the world’s largest twin-engine jet, is expected to enter service in 2025, so this concept exists purely on paper for now. But Lufthansa, which will be among the first ...
The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. [12] They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747. [12]
