One of the most powerful electric locomotives ever built, it also is the most powerful single-frame locomotive ever built (currently [when?] its maximum short term power is limited to 12,000 horsepower (8,948 kW)); 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: Deutsche Bahn
The AC6000CW is a 6,000-horsepower (4,500 kW) diesel electric locomotive built between 1995 and 2001 by GE Transportation. It is among the world's most powerful single-engined diesel locomotives. The locomotive was designed for extremely high horsepower needs, such as pulling heavy coal and ore trains.
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] Union Pacific has marked DD40X on the cab exteriors, while EMD literature ...
The Pennsylvania Railroad 's class Q2 comprised one prototype and twenty-five production duplex steam locomotives of 4-4-6-4 wheel arrangement built between 1944 and 1945. [1][3][4][2] They were the largest non- articulated locomotives ever built and the most powerful locomotives ever static tested, producing 7,987 cylinder horsepower (5,956 kW ...
The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA 's Tier 2 locomotive emissions standards that took effect in 2005. The line is the direct successor to the GE Dash 9 Series. The first pre-production units were built in 2003.
2-6-6-6. The 2-6-6-6 (in Whyte notation) is an articulated locomotive type with two leading wheels, two sets of six driving wheels and six trailing wheels. Only two classes of the 2-6-6-6 type were built. One was the "Allegheny" class, built by the Lima Locomotive Works. The name comes from the locomotive's first service with the Chesapeake and ...
Union Pacific 844, the only steam locomotive never retired by a North American Class I railroad. The 4-8-4 wheel arrangement was a progression from the 4-8-2 Mountain type and, like the 2-8-4 Berkshire and 4-6-4 Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which ...
It ranks among the heaviest and most powerful non-articulated steam locomotives to operate, and one of the largest surviving steam locomotives in preservation in the United States. 643 is also one of only two 2-10-4's to be restored to operating condition after retirement, the other being the aforementioned T&P 610.
