Here is another version, this is an ultra modern version.
The major focus is grain, and containers.
The concept here is an out an back branchline operation. This means a crew would sign on at the major yard and then head off to a silo location, load and return, in one shift if possible.
However its not as easy as it seems, as per prototype most of the loops are shorter than the average train, with a one silo service, this means some tricky shunting and ensure that you are not blocking the road, on ute for shunting, so more ground work, and then train order etc.
One loading point does not even have a run around loop, lots of re arranging.
finally a main line only hard stand area, so an out, run around then back to the hard stand location and strip and back load.
