I worked for many years at Ashland Oil's Catlettsburg Refinery. The C&O/CSX Main Line South to Tennessee, passed by our complex. We had a nice yard there, with Tank/Hopper Car loading/unloading facilities. We also had a repair, and car cleaning site, at the far south end of the refinery.
The railroad would bring empty/loaded cars to the refinery. Then spot the cars for processing, when ready, they would make up their return train back to Russell, Ky Yards. Until about 6-8 years ago this was handled by CSX only.
Sometimes there would be new process equipment brought in by rail for maintenance dept, or construction groups.
There was a time in the mid 80's where catalyst and limestone dust was brought into one of the units, that had an off site silo operation, and they used a Track Mobile, to move the loaded, unloaded cars in and out for processing. New Technology eliminated this operation altogether.
CSX turned this full time switching operation over to R.J. Corman Co, as the new modern thinking is, the railroads want to run from point A > B, and thus eliminating the old "Local Freight" runs.
So this is the reason so many "Short Line Railroads" have come into being.
Now if a spot was missed, and we could catch the crews before they left, we could get them to respot these these cars, if not, we would have our loaders manually move these cars on spot. We had what was called a "Car Jack", and this was used with success for many years.
Down side, it was by the luck of the Good Lord, that someone didn't get maimed or even killed, as the tracks on these loading racks, were anything but level, and to move one, you had to of course loosen the brakes to get them to move, sometimes it took several guys to do this operation.
The Railroad would charge $200.00+ per car to respot, unless it was their fault. I was responsible for that operation for a number of years, and bought my guys a couple of Loaded 18" Pizza's on a weekly basis, and I would always get some for the Railroad Crews.
The Company never got charged for respots when I was minding the store!
The guy that replaced me said that "Kindness Showed Weakness", and stopped the "Creature Comforts Altogether". I guess a difference in management Philosophies Ya Think?......................Probably way more than what you wanted, but that's the way we did it!..................................Brandy!
