A short line railroad or branch line with the same tractive effort requirements might require up to 2000 horsepower to move the train because of the higher speeds involved. Main line locomotives may need over 4000 horsepower each with multiple units because of both high tractive effort and speeds.
How much force does it take to pull a train car?
If the weight of a fully loaded rail car is 280,000 pounds, then F = (0.001 x 280,000) = 280 pounds. Because the only horizontal force that the railroad car produces is the friction force, the force to move the rail car (P) is equal to the friction force (F).
How much power does a train engine?
According to the specifications provided by the Railways, these locomotives are state of art IGBT based, 3 phase drive, 9000 KW (12000 horsepower) electric locomotive. It is capable of the maximum tractive effort of 706 kN, which is capable of starting and running a 6000 T train in the gradient of 1 in 150.
Do trains push or pull?
The extreme efficiency and success of these trains is why almost all of the commuter rail services in the United States and Canada utilize 100% push–pull operation on their locomotive-hauled trains.
What is the most powerful train?
All hail Mother Russia: with 17,838 horsepower, the Novocherkassk 4E5K locomotive is the most powerful in the world. It seems like digital espionage isnt Russias only path to power.
Do train engines push or pull?
In real life, many train companies use both push and pull methods. In a push-pull train, you have dual locomotives in the front and back, sometimes working together, sometimes taking turns. Companies also do pull trains one way and then push them back, saving cost and having to turn the train around.
How fast do trains accelerate?
Just to give you an idea of what can be done with modern electric locos - the class 189 electric of German Railway, rated at 10,000 hp, accelerates a 2.000 mt freight train from 0 to 65 mph in less than 20 seconds.
Is push or pull stronger?
The results suggest that for our group of healthy recreationally active subjects, the upper body “pushing” musculature is approximately 1.5–2.7 times stronger than the musculature involved for pulling.
