Jerry, if you look at the video I did this year (Last Steam Freights 1968) you can clearly see some cars with these notches at the top of the gons. I believe it shows on a Chama-Cumbres train if I remember correctly. I remember we discussed this when I was making the video.
Interesting stuff! When I get ready to do something with my transfer footage will get back to you for some info on it. I have some around here already. When did they stop using the Baldwin coal at the transfer
in Salida?
