I will be up at the EBT this weekend and will determine then which cars were taken to Chama. That does not mean that I will be able to determine the road nembers, but I had previously recored the road numbers on all the cars still at the EBT that had even one remotely legible number. I will post the results here when I get back.
The ones we know so far are 1044, 978 and 888.
