How much horsepower do trains have?

Steam locomotives generally have about 3,000 horsepower, internal combustion locomotives can have 4,000 to 5,000 horsepower, and electric locomotives have 10,000 horsepower or more.

For electric locomotives, the unit of horsepower is not used, internal combustion and steam locomotives are the only ones that may use horsepower.

But now generally use kW as a unit, the conversion is 1 hp = 0.735kW

Domestic internal combustion locomotives (6-axle) can be seen at present is in the range of 2400-3000 such, the largest is the Dongfeng 11 modified locomotive, 12-axle, 6000kW

Electric locomotives are more powerful than the internal combustion locomotives, domestic 6-axle electric locomotives are currently Generally are 4800kW, the largest is the 12-axle Shaoshan 3B fixed heavy locomotive, 8640kW.

The above all refers to DC locomotives, if it is an AC locomotive, then the power is greater, for example:

Domestic AC locomotives have been in place, the internal combustion locomotive has more than 5,000 horsepower, that is, 3,700kW, seems to be more than 6,000 horsepower in the development of the

Expansion of the domestic AC locomotive has more than 5000 horsepower, that is 3700kW, in development seems to have more than 6000 horsepower,

Domestic electric locomotives at present is the level of 1200kW a shaft, that is, a six-axle locomotive power can reach 7200kW, in the development of locomotives can reach the level of 1600kW a shaft, the use of 8-axle, that is, the total power can reach 12800kW. Information:

Locomotive Advantages

The internal combustion locomotive, although it came out late, but it came later, than the big brother of the train family, the steam locomotive's competence, and is valued by people. Its outstanding advantages are:

1, fast speed: internal combustion locomotives start quickly, accelerate and fast. Usually, the maximum speed of the steam locomotive is 110 kilometers per hour, while the maximum speed of the internal combustion locomotive can reach 230 kilometers per hour, so that the railroad throughput capacity increased by more than 35%.

2, horsepower: the power of steam locomotives generally about 3000 horsepower, while the internal combustion locomotive can reach 5000 ~ 8000 horsepower, and thus more capacity.

3, can better utilize the thermal energy of the fuel: the thermal efficiency of steam locomotives is generally only about 7%, while the internal combustion locomotive can reach about 38%, an increase of 6 times, thus saving a lot of fuel.
