What motor is in a train?

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.

What motor does a train use?

Diesel engines are used in many types of vehicles, including locomotives. Diesel engines have a fuel efficiency 20 percent greater thermally than a gas engine.

How many HP is a train engine?

"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)."

What size engine is in a train?

It's 72 feet, four inches long; 13 feet, 7 inches wide; and 15 feet, 7.5 inches tall at its highest point. The competing General Electric C44-9W (popularly known as the Dash 9) weights 400,000 pounds.

Is there a motor in a train?

A locomotive or engine is a rail transport vehicle that provides the motive power for a train.

The Fascinating Engineering behind Electric Trains!

Are trains AC or DC?

Third rail systems almost exclusively use DC distribution. The use of AC is usually not feasible due to the dimensions of a third rail being physically very large compared with the skin depth that AC penetrates to 0.3 millimetres or 0.012 inches in a steel rail.

Do trains use electric motors?

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.

Are trains diesel or electric?

A few passenger rail lines have been converted to electric power in the United States (Amtrak's Northeast corridor and Harrisburg, PA, line), but the rest of passenger rail and all of freight rail is diesel-powered.

How fast can a train go?

Trains regularly reach speeds of 125-150 mph (201-241 kph).

How much CC is a train engine?

The engine is also called a “Prime Mover”. These engines are huge, usually having 16 Cylinders, 32 Valves and about 100,000 to 150,000 cc displacement.

Do trains have gears?

Train engines also have gears like ordinary vehicles.

Why train engines are not turned off?

Trains, being large and heavy, need the optimal brake line pressure for its efficient stopping. For obvious reasons, loco pilots never compromise on brake line pressure. Another reason for not turning off diesel train engines, lies in the engine itself.

How much fuel does a train hold?

Typically, tank cars have up to five times the capacity of truck, holding between 6,500 gallons to more than 31,000 gallons of liquid.

Does Cummins make a train engine?

Wherever there's advanced rail technology, you'll find Cummins power. Under the floor on Europe's high-speed passenger trains.

Are trains diesel?

Diesel locomotives or trains run using diesel fuel. If you believe so, then you are not entirely right. Modern diesel trains use electric motors known as 'traction motors' to supply power to the wheels. The diesel power plant just supplies the power to the traction motors, and does not turn the wheels.

How much torque does a train engine have?

Each motor is set transversely between a pair of drive wheels. On an Evolution the electric motors will put out a total of almost 60,000 pound-feet of torque at start-up–the equivalent of about 120 Ferrari Enzos–good for a zero-to-60 time, unloaded, of just shy of 45 seconds.

Why do trains go faster at night?

Signal visibility is good at night compared to daytime one can see the signal from far away, so the loco pilot drives the trains at full speed at night.

Why do trains go so slow?

Because the tracks don't have a lot freedom to move, they're tied down at high temperatures (95 - 100°F) to try and reduce the amount of expansion in the summer heat. When the rails are already heated by weather, the added energy from the train traveling over the tracks can be enough to cause them to become too hot.

Why are American trains so slow?

The Track is the main reason passenger trains are so 'slow' in the US. The passenger rail service in the developed across most of the country as a supplement to freight rail. In the 20th century as personal vehicles and roadways capable of long distance travel developed - passenger service income declined.

What are trains powered by?

Most trains are powered by diesel engines or by electricity supplied by trackside systems. Historically the steam engine was the dominant form of locomotive power through the mid-20th century, but other sources of power (such as horses, rope (or wire), gravity, pneumatics, or gas turbines) are possible.

What fuel does a train use?

Diesel fuel is stored in a fuel tank and delivered to the engine by an electric fuel pump. Diesel fuel has become the preferred fuel for railroad locomotive use due to its lower volatility, lower cost, and common availability.

How do trains get their power?

Besides steam- and diesel-powered locomotives, many trains operate solely on electrical power. They get the electricity from a third rail, or electrical line, along the track. Transformers transfer the voltage from the lines, and the electrical current drives the motors (AC or DC) on the wheels.

Which motor is used in metro train?

THREE PHASE SLIP RING INDUCTION MOTOR has been used in DELHI METRO. Dc series motor is ideal for traction but the maintenance cost of which is very high also needs the conversion and smoothening of AC voltages.IM has less maintenance,high starting torque, cheap etc.

How much diesel does it take to start a train engine?

Much depends on the size of the composition, because it varies according to the weight of cargo being added to the total weight of the composition (train) and the type of engine power and speed and he travels and the type of slope of the rail line can reach 50 liters of diesel per kilometer, or hours worked, because ...

How many engines does a train have?

There is a limit to how many locomotives can be added to the front of a train, but in general there can be up to six or seven without a problem. Most trains in North America will have at least two locomotives.
