I ran across this car taken in Dallas, TX in 1963 by Joe Hughes on www.rrpictureachives.net. I had never seen such a car, so I looked them up in the January 1963 O.R.E.R.. They are coke boxcars with open roof and six side doors. They are #1000-1003 but there are only three of them. Joe Hughes said the car # is 100 but the end sill says this car #1001. Does any one know any more about these cars? My guess is they were used in Birmingham, AL steel mills.
