How long dose it take to load a ..?

Many years ago a phosphate rock mine in Idaho tried to extend the shipping season of ore into the winter - so they sprayed the cars with antifreeze before loading them with rock. At the concentrator end of the run the pulled the treated cars into the rotary dumper and rotated the first car. Thunk -out comes the rock - in one frozen solid 50 ton chunk. The antifreeze worked but the ore still froze. They had to break up the popsicle with jack hammers!

I havent had a chance to see them load coal but I know its done with fload loaders and they continue to pull the train through the loader at slow speed train doesnt stop. This is the way its done in the powder river could be different at other places.

Petrex has an excellent video of a flood loader loading a coal train in the powder river basin. The train pulls through at a crawl. The flood loader has 2 bins, one loads the front, the next the back. It takes about 1 minute per car. The whole train takes about 2 hours. The car is also weighed in motion, before and after loading, and the bins are weighed before dumping. I don’t remember which mine was shown.
