One of the fascinating things about reading these posts is how quickly it changed. The picture presented by these posts is of a terminal with a lot of round-the-clock daily activity, and a home base for helpers. Almost continous stuff going on.
By 1960, three years later, Chama was typically busy only four days per week, the helper base was gone (when did they blank the roundhouse foreman's job at Chama?), and there were no more night time departures. For over three days every week the place was dead as a doornail. Trains typically left Alamosa and Durango on something like Mondays and Thursdays, so you'd have trains arriving Chama in the late afternoon or evening of Monday and Thursday, busy days on Tuesday and Friday with hill turns and a departure for Durango. Then on Wednesday and Saturday the third cut would head up the hill early in the morning to put the train together at Cumbres, and head east. So from Wednesday morning to Thursday night and from Saturday morning to Monday night it was dead.
And of course it went downhill from there.
