The C&TS began using daily train sheets in May, 1992. All the info should be on those. There are probably copies of old call sheets back to around 1987 somewheres in my old files in Chama. I have all my old call sheets back to 1981-2 somewhere stuffed in a box. There might be 1980-1 somewhere in Chama. I have never seen anything before 1980. I don't know how the crews were called and scheduled when John Oldberg was running the show. Remember, back then there were only 4 trains and 2 helpers a week. There were 2 engineers, 1 conductor, 3-4 firemen/brakemen. Life was a bunch simpler.
