That sounds really interesting, BTW check your PM inbox please. I asked you something.No this does not function that way in Load/Unload all mode. You can drop the traincars at the industry and continue along while they are loaded/unloaded over the amount of time you have set. AI trains can be set to uncouple and leave cars at the industry and move on to the next assignment. The supply or demand come from the industry so no load or unload command is necessary in this mode. If you leave a traincar inside the loading boundary with a load the industry demands, or if the car can accept loading of something the industry provides, then the industry will attempt to transfer between them. You may even add or remove or reposition cars inside the boundary during the process; If the industry detects a car that is loading/unloading is moved it will enter a waiting period to determine if it can resume, or in the case the car was totally removed from the area, wrap up the operation and mark the car off the list.
With the unload while moving mode you may assign an AI driver with a load or unload command and they will drive over the moving load/unloader at the correct speed (thus not allowing control until complete with the driver command), but you may also drive the train manually at the correct speed if you wish.
in load all mode the loading area boundary can be extended to 200m sure.
Thanks!
