If you have more and are interested in putting them up as freebies, I can guarantee you, there will be a lot of very happy railfan artists out there. :c)  I can guarantee you, you'd see me using them for a while, that's for sure.  What you have there is a good modern car, meaning post 1930 steel car.  I've 2 locomotives that I have been sitting on for the most part because I had no good rolling stock to go with them.  So these would be a major boon for me if you are so inclined.
