Thanks for the information Earl. I guess I never really counted the number of fish belly versus non fish belly passenger cars. I also had wondered about the standard gauge flats and you have answered that as well. I noticed last year an odd underframe that was on trucks in antonito. This year it no longer had trucks under it. What did that used to be? I remember taking a close up shot of this metal plate on it that showed the layout of all of the brake rigging. Seemed like an expensive diagram to add to every car. I think it was CB&Q but I could be wrong.
