As the tail end DPU's move away in this shot, note the "yellow/red" board on the right side of the track in the distance. This board indicates that the train is two miles away from a red board (looks the same except it is entirely red). A train is not allowed to pass a red board without permission from the track foreman in charge, regardless of what indication signals might be giving a train. The crew knows what foreman to contact thanks to "Form B" paperwork that the conductor has with him. On this day, the "Form B" is between Arvada (CP DS007) and C&S Junction (CP DS005) as crews work to complete construction of the new Main 2 track. The red boards protect the maintenance crews from trains. Once the train contacts the foreman, the foreman will make sure his men are clear of the tracks and then give the train permission to proceed past the red board and through the Form B limits.
