My industrial area feeds off my main layout. Cars arrive and depart in 10-12 car trains. Here a train is awaiting departure on the arrival/departure track.
After arriving, cars are sorted into two separate industrial switching jobs and set up for delivery to east and west areas separated by a river. The following is the schematic and overview of the West side.
Here’s the east side schematic and overview.
It takes me about an hour to receive the arrival train, set out the departure train, sort and block the two industrial jobs, do the pickup and delivery for both jobs which puts me in a position to restart the process the next time I go downstairs!
