Teach me something…. Okay, this is pretty simple, but I want to know if I am thinking correctly about the jobs of the crew members. I’ll give commentary on what I think should happen. Someone please chime in if I am missing anything. Again, what I am interested in is the jobs of the crew members. There is a train traveling west that needs to set out a car on the trailing point spur. We have an engineer and a brakeman in the loco, and a conductor in the caboose. The locomotive is the gray rectangle. The caboose is the green rectangle. The blue car is to be set out on the spur. The brown cars will remain traveling west with the train. In the first diagram, the train has traveled west and stopped in the position as shown. The brakeman exits the loco, walks the track to the east end of the blue car, disconnects the air hoses and uncouples the car from those to the east. The conductor remains comfortably in the caboose, shuffling papers.
