West Tulsa Railyard

Alright, here is a little bit of information I found about the railyard.
It is currently owned by BNSF which is Burlington Northern Sante Fe. It is more commonly known as the Cherokee Yard.
The railroad was brought first to Red Fork in 1884-1885 by the Atlantic and Pacific railroad company which was later purchased by the St. Louis and San Fransico railroad company in 1897.
There is a good article from the magazine Trains that has more information about how many trains run through Cherokee a day, what type of goods they traffic, size etc. Click here for the link. The Tulsa Sapulpa Union railroad runs through there. They traffic goods and materials for the glass plant and sinclair refinery to name a few. Mainly traffic for business between Tulsa and Sapulpa.
There really isn't much information about the history or what it was used for that I could find. I did read that the rail system in Red Fork was used as a staging ground for cattle in the late 1800's. You can get some more information at the tulsa preservation commission website. Their phone number is 918-576-5687. They might have more information.
I think this story would work if you took it as more of the history of the rail system in Tulsa with a little spotlight on the Cherokee yard. I don't know if you could dig up enough info for just the west tulsa railyard and its history.
We might also consider a story about oil. Oil was first found in Tulsa County in Red Fork. It spurned Tulsa to become the oil capital of the world. It might be a good story to look into that.
