Thanks for the compliment on the pictures. More to come as time permits.
The Chicago Terminal Railroad follows the same schedule as the CP Rail crews, with crews starting work on Tuesday and Thursday mornings, completing operations by late afternoon typically before heading back to the North Avenue Yard.
The number of empties and full loads for each industry determine in which order the industries will be services. Cars are blocked in whatever is the most logical sequence that day to minimize doubling back or extra switching. There is no set schedule otherwise.
