I've seen it in prototype operation and I've seen it on film where a
locomotive will be put somewhere in the middle of a train to help move a
really heavy load such as a coal unit train. But can someone tell me how
this actually works.

If the loco in the middle is actually pushing the cars in front of it, then
it would take the slack out of the couplers of the locos that were pulling,
and they would no longer actually be pulling against anything.

Does the loco in the middle actually just keep the slack out of the coupler
just in front of it and actually pull everything behind it or what. I can't
seem to comprehend how this operation works.

If this were the case, then it would appear that it would take a lot of
skill on the part of the operator in the middle locomotive. Someone told me
that there were no operators in the middle loco which is probably true
today, but I have seen film where this operation was done with steam too.
