How many cars can an scale train pull?
How many cars can an scale train pull? The two important questions are how fast do you want them to run and how steep is the grade. One unit can easily pull 100 cars on the flat if you only want it to go 10-12 mph. Put it on a 2% grade and a 3000 hp unit can only pull about 6-8 cars at about 15 mph. Western RRs usually rate their trains in Horsepower/ton.
How does a train pull so many cars?
They rely on precise track. Rolling resistance of nicely round steel circle on nicely smooth steel rail is negligible to rubber-tarmac contact. The other thing it utilizes is the locomotive weight. The contact pressures in the wheel-rail contact are very high and they use sand to increase the traction.
How long does it take a 100 car train to stop?
The average freight train consisting of 100 cars and weighing anywhere from 12 million to 20 million pounds takes over a mile to stop in emergency braking.
Can a f5 tornado pick up a train?

Why do trains have 2 engines?
Anyway, the reason for using two locomotives is pretty simple. Twice the number of locomotives means twice the power. This extra power boost is used for especially heavy loads or for trains going up steep grades.
How much horsepower does a train have?
While the average car engine has about 200 horsepower, locomotive engines typically range from 2,000 to 4,500 horsepower.
What is the lifespan of a train engine?
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Why train engines are not turned off?
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
Why do so many cars break down on train tracks?
One instance is where the railway track is at a slightly higher level than the road approaches on either side. A long vehicle such a s a low loader can become grounded on the “hump”. Another situation is where, at a level crossing, a driver mistakenly leaves the road and turns onto the tracks.
How much fuel does a train use per km?
The average fuel consumed per kilo- meter for all passenger and cargo trains is 7.97 L/ km. This value for local, trafficking, railway track laying and maneuvering trains is 7.92 L/km.
