How many wag 12 are there in India?

They entered trial service in 2019. A total of 224 WAG-12B have been built at Electric Locomotive Factory, Madhepura, Bihar, India. With a power output of 12,000 HP, the WAG 12 is twice as powerful as its immediate predecessor, WAG-9, and is among the most powerful freight locomotives in the world.

What is hauling capacity of locomotive?

Solution. (a) Hauling capacity of locomotive. = no. of pairs of driving wheels x axle load * coefficient of friction = 4 x 28.42 x 0.2 = 22.736 t. (b) Total resistance of train = resistance due to friction + resistance due to speed + resistance due to wind + resistance due to gradient + resistance due to curve.

What is the top speed of WAP 5?

The WAP-5 type electric locomotive, capable of running at 200 kmph, is of 5400 HP capacity and is equipped with propulsion system.

What is the cost of WAP-7 locomotive?

WAP7 was thus saved from being guillotined. Today, the WAP7 is the flagship passenger locomotive of IR, with more than 1,000 in service at a total investment of almost Rs 15,000 crore.

How do you calculate hauling capacity?

Subtract the curb weight from the GVWR to find the payload capacity. For example, if you have a light-duty truck with a GVWR of 9,000 pounds and a curb weight of 6,000 pounds, the payload capacity will be 3,000 pounds: GVWR – curb weight = payload capacity. 9,000 pounds – 6,000 pounds = 3,000 pounds.

What is Max payload?

What is Payload Capacity? A vehicle’s payload capacity is the maximum amount of weight it can safely carry. In a car or SUV, that includes all of the weight in the cabin and trunk. In a truck, it consists of all of the weight in the cabin and bed.

How many HP is a train?

A modern locomotive can have anywhere from 1000 to 18,000 horsepower, depending on the power source, model, and year of production. The average power of a train engine can vary greatly, but almost all options offer a level of strength and durability that would be unthinkable a few decades ago.

What is the CC of train engine?

These engines are huge, usually having 16 Cylinders, 32 Valves and about 100,000 to 150,000 cc displacement.

What is the difference between WAP-5 and WAP 7?

And second, by using 2 WAP 5 locomotives of 5400 HP, the total horsepower is well over 10,000 HP, which is considerably greater than a single WAP 7 electric locomotive with a horsepower of around 6,000 HP.

What is the top speed of WAP-7?

180 km/h
With a maximum speed rating of 180 km/h, the WAP-7 boasts of the most phenomenal acceleration figures while hauling mail/express trains. The WAP-7 can also haul loads of 24-26 passenger coaches at a speed of 110 plus km per hour. It is also known to haul 16 heavyweight Air Conditioned coaches.

What is the meaning of WAG-9?

The Indian locomotive class WAG-9 is a class of 25 kV AC electric locomotives that was developed in 1995 by ABB Group (ABB) for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G), 9th generation (9) locomotive. They entered service in 1996.

What is the rate of change of breaking effort for WAG9 locomotive?

This level of control shall be applied to the Locomotive and it shall be maintained throughout the tractive effort curve. 3.7.3 For the existing WAG9 Locomotive the rate of change of breaking effort is limited to 100 kN/second.

What is the top speed of WAG7 and WAG9?

The top speed of WAG-7 is 120 km/h but while working with passenger train it is restricted to 100 KMPH only. The top speed of WAG9 is 100 kmph, and it can work with passenger trains on top speed. Why are WAP 3, WAP 6 and WAP 9 locos not common? Which trains are hauled by them?

Why is the WAG-9 so hard to drive?

Because the WAG-9 is quite heavy there are restriktions about where she may go. In addition, two-axle bogies are not as brutal with the track as three-axle bogies. The other thing is: If more power is needed, you can couple two WAG-12s together and drive as a multiple unit -> 24,000 kW. With the WAG-9, only 2 are allowed in MU mode.
