On a good day, my little shortline starts out at the East Yard with a cut of 6 to 12 cars which were delivered to us by the SP. These cars are bound for the industries we serve. We head west, and drop off the cars, at the same time picking up cars which need to be delivered to the West Yard on the opposite end of the layout, which is the intechange with Santa Fe. Once we have dropped the pick-ups off in the West Yard, we grab a cut of 6 to 12 cars from the Santa Fe and head back east, making the drops at the industries and also picking up any cars headed to the East Yard. Once that is done, we head back east and drop the cars so the SP can pick them up, and our day is done. (unless it is a real heavy day, and we have to make another run). So, considering the above, how many crew members would be on the train? What would their titles be? Any info on their actual job assignments? This is the 1970s, but I probably will not run cabooses because the trains are so short. Am I correct in this?
