Question

Has anyone done a study to see the average spillage of a coal train?

Answer 1

Transportation fact concerning all modes...air/sea/land/rail...By far the smoothest method of transportation is by rail. INsurance studies concerning claiims agains rail carriers ahve proven  that statistic year after year. As a matter of fact it is not even close.....Virtually no coal is lost while in transit barring any aborted traveling such as a sudden emergency braking of course...

Answer 2

Sure, they look at that a lot, even .1% would be significant, any spillage at loading or unloading facilities is cleaned up and the coal blowing off cars in transit is not enough to be measurable.  

Answer 3

Most CERTAINLY... as Andy points out, today there is VERY little spillage.  BECAUSE there were studies that determined that there was quite abit of spillage.

If you look at a modern coal-load, it looks like an uncooked bread-loaf... it doesn't rise up as high as the top of the hopper... so that nothing is disturbed.

Answer 4

You mean how much coal falls off a loaded coal train while it's moving? Virtually none.Maybe a piece or two here and there,but i have had coal trains that had chunks of coal sitting on the edge of the cars that was still there at the end of the trip.
