50 metres, or 50-meter dash, is a sprint event in track and field. It is a relatively uncommon non-championship event for indoor track and field, normally dominated by the best outdoor 100 metres runners. At outdoor athletics competitions it is used in the Special Olympics and a rare distance, at least
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.

A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
They were built under the same premise that a lower power rating than the 4,400 hp (3,300 kW) rating of the Dash 9-44CW (or C44-9W) (see below) would prolong the life of the engine, and use less fuel. However, there is a manual override switch that allows the engineer to run the engine with all 4,400 hp (3,300 kW) if necessary.
The Jamaican sprinter Usain Bolt produced a maximum of 3.5 hp (2.6 kW) 0.89 seconds into his 9.58 second 100-metre (109.4 yd) sprint world record in 2009. [14] [failed verification] In 2023 a group of engineers modified a dynamometer to be able to measure how much power a horse can produce. This horse was measured to 5.7 hp (4.3 kW). [15]

This model is a variation of the C40-8W with the same 16-cylinder engine uprated to 4,135 hp (3,080 kW). A total of 154 C41-8Ws were produced between 1993 and 1994 for both UP and ATSF. Some Dash 8-40CW units were similarly uprated to Dash 8-41CW standard by the railroads. Power output: 4,135 hp (3,080 kW)
