Nice layout! I like the town- Tombstone. I was in Tombstone, AZ this past winter. Don't forget the newspaper office- The Epitaph.
I've been working on an old west town myself. So far I have completed the sheriff's office/jail and I based it on the one used in "Rio Bravo" with John Wayne. I am now working on a saloon and a gun shop.
As others have said, there are some box cars put out by MTH that are right for this period. I believe they call them "19th Century Freight" or something like that. I use two of them with my Lionel General.
Thanks for the video!
