“Most electric locomotives weigh between 100 and 200 short tons (90 and 180 metric tons) and provide about 6000 to 7000 horsepower (4500 to 5200 kilowatts).”
How much horsepower is in a train engine?
In a diesel–electric locomotive, the diesel engine drives either an electrical DC generator (generally, less than 3,000 horsepower (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 horsepower (2,200 kW) net or more for traction), the output of which provides power to the traction …
How many HP is a diesel train engine?
How many horsepower is a diesel locomotive? A locomotive’s diesel engine is connected to an electric generator that is either DC or AC. In either case, the power produced is around 3,200 horsepower. The generator uses this power to convert it into a massive amount of current, approximately 4,700 amperes.
How much horsepower does locomotive engine have?
How Much Horsepower Does A Train Locomotive Have? The output of electric locomotives varies between 5000 to 7000 HP (4500 to 5200 kW). They generally consist of 100 to 200 short tons (90 metric tons).
Why do trains have 2 engines?
Advantages. Double heading is practised for a number of reasons: The most common reason is the need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the two.
Do trains have turbos?
turbo train, high-speed passenger train powered by a gas-turbine engine similar to that used in jet aircraft. Unlike conventional trains, the turbo variety does not have a separate locomotive; its turbine power unit is small enough to be built into a passenger car.
How are trains so powerful?
Electric locomotives are powerful and have traction motors fitted in all coaches. So, starting and accelaration is instant in case of metro trains. Some trains have double engines to pull higher loads. The two things that make this possible are HORSEPOWER and TRACTION.
Are train engines electric?
Although commonly called “diesels,” the locomotives actually are electrically driven. The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive’s axles.
How much HP does a steam train have?
A Big Boy locomotive along with its tender weighed about 604 tons and measured more than 132 feet (40 metres) in length. It had a maximum power capacity of more than 6,000 horsepower and could haul a 3,600-ton train unassisted up the Wasatch Mountain grade.

What does DPU mean on a train?
DPU – Stands for Distributed Power Unit, a locomotive set capable of remote-control operation in conjunction with locomotive units at the train’s head end. DPUs are placed in the middle or at the rear of heavy trains (such as coal, grain, soda ash and even manifest) to help climb steep grades, particularly in the West.
What is the cost of a train engine?
