Cool photos, especially 1, 4 and 5. Good to see 484 and 483 together again. Except for the lettering(Which is not that easy to read from here), this could very well have been a 1950-60's train during the Grande days. Also interesting to note that 1973 was only 5 years removed from the last D&RGW trains over Cumbres!
Thanks to William and Jerry for sharing the pics.
