So here it is. Steel wheels on steel rails = a very low rolling resistance. So the engine power (you) hasn’t changed, but simply by reducing the rolling resistance (call it friction if you like) even a small child could pull a big heavy chair along a smooth surface. That’s why an engine can pull a big heavy train.
That totals 27 MILLION pounds of weight pulled (or 14,000 tons). Depending on the type of locomotive, steepness of the grade of track, and sharpness of the curve in the railroad track, a loco may pull more or less weight.
ON JUNE 21 BHP Iron Ore set a new world record by running the longest and heaviest freight train, between Yandi mine and Port Hedland in the Pilbara region of Western Australia (below).
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.
A penny left on a track does not typically derail a train. A train speeding along its track is a very heavy object with an immense amount of momentum. The penny is simply too light to do much of anything. Flattening pennies using trains is still dangerous though; to the people placing the pennies.
Another reason for not turning off diesel train engines, lies in the engine itself. It is also interesting to know that while diesel locomotives are idling, fuel consumption is more than when the train is moving. This is because, while idling, the batteries are being charged, and the air compression is in operation.
moving in a train, 3-4 locomotives would be required. Through advances in technology higher horsepower locomotives have been developed whereby 4000-5000 HP locomotives are capable of moving 1 ton with. 80 HP.
It takes about 10 pounds per ton to accelerate to a speed of 6 miles per hour in one minute or 12 miles per hour in two minutes, a reasonable rate for a heavy train.
Also, if your engines can do it, it’s fine, but I’d say 30 cars are a lot for a model engine. I’ll run a 30 car ore train with a 2-10-4 or 2-6-6-2 but for diesels I generally use two engines for most trains, even moderate (10-12 car) freight trains.
On passenger trains, some of the passenger service staff, like the cooks or dining car attendants, etc, sleep on the train, but the operating crew (Conductor, Engineer) does not. When they deadhead, they are not responsible for the operation of the train, they are just there for the ride.
Pulling well more than 100 cars, the trains are much longer than — and in some cases more than double the size of — a typical 5,000- to 6,000- foot train. Canadian Pacific, CN and Union Pacific Railroad have incorporated long trains into their operating strategies and continue to aggressively push the length envelope.
So, we can VERIFY that Norfolk Southern freight trains can be up to 1.5 miles long, and there is a state law against trains blocking the road for longer than five minutes. However, the rule only applies if the train has insufficient cause to block a crossing, and state law can be preempted by federal regulations.
Thanks in part to these technologies, today U.S. freight railroads can, on average, move one ton of freight more than 470 miles per gallon of fuel, making rail an environmentally friendly way to move freight over land.

The Union Pacific locomotive, known as “Big Boy” 4014, is the largest locomotive ever constructed.
