THANK YOU, Jimmy!!
The only information that I can add is that the engineer on helper #483 on the last
westbound revenue freight - August 28, 1968 - was Eldon Morgan and the fireman
on road engine #484 was Jim Shawcroft.
Two of these have been posted before, but to save time searching & linking here's Jim in his cowboy hat as the train departs Alamosa:
... the crews servicing their steeds during a drizzly lunch stop at Sublette:
... and Eldon running #483 as she departs light from Cumbres toward Chama:
