Hey everyone! I have a few questions about the 5900 series stockcars. I was wondering why where they all dismantled? I asked this because it seems to me that they would have been better to use then the smaller 30 footers and they were newer. Was there something wrong with them. I did read that the Rio Grande wanted there trucks from under them, but couldn't they have put the trucks from the smallers stock cars under the 5900 series? I hope someone has some more background info on the history of the 5900 series stock cars.
