1971 C&TS Trains

I am wondering if there is any sort of documentation of the first year of trains on the C&TS. What I am getting at is a list or log of each trip, including date, start and destination, and maybe other info like the engine and how many cars used, or number of patrons.

Since the 50th year of that first season of excursions is next year, I would like to see some info if it exists. I visited twice, and would like to nail down the exact dates perhaps if possible, though it may not be possible. The first trip was in late June, I believe 2 weeks after the first run. I think we were there over July 4th weekend, but maybe not. The second trip I believe was in September perhaps around Labor Day. Back then the trip options were varied, as one day might be Antonito to Sublette, or something different. I recall 484 on a trip to Sublette and back tender-first at MP 305. I think someone suggested that they might have turned the engine at Big Horn. I thought I remembered them coming into Antonito tender-first, but could be wrong.

Anyway perhaps someone knows the schedule for 1971, or some sort of info on those trains in the first year of public excursions. I think we rode a trip from Chama to Cumbres in September for $5.00 or $10.00. That was my first ride on that part of the RR since my only ride on the Rio Grande over Cumbres when I was 5!!! Lets just say that was in the 1950's!!!
