I'll post,the reply here on the Q group and hope you post it to the J group.
At Eola in the 60s and 70s (the time I had first hand experience) the typical pattern was as follows.
Prior to midnight the J would deliver 60 or more cars to the Q/BN upstairs in their yard North of the Q. A Q car inspector would work the cars. Next morning the west yard day engine would pull the transfer down into west yard one or two and then switch the cars into either west or Nothbound blocks. The vast majority of the cars were loads of steel plates,angles,etc in gons and on flats. There were also loads of tinplate in J box cars.
All day long the Q east yard jobs would throw mtys and a few loads into either trk 12 or 13. In the evening the J car knocker would inspect the cars. Any bad orders were pulled out by the east yard 4 PM job. Then the J would come down the south leg of their wye and pull the transfer.
Each and everyday,7 days a week this routine took place.
Now there is almost nothing except the unit trains.
