I downloaded the latest version, then made some changes to my set-up. I dumped all of my 1:29/1:24 cars & locos and put in all my 1:20 stuff. I added a new industry at the new siding and got rid of industries located on the Wye. I now basically have an origination yard, 3 industries and a destination yard. I changed the physical layout so that it flows from the originating yard , through the wye and past the industries ending at the destination yard. Both yards are indoors. A single Daily out-and-back train was made up that services all the industries.
So far it seems to be working well except one industry is not being served. It is looking for loaded hoppers and tanks. There is one of each loaded in the destination yard. I think I can force delivery if I originate a train in that yard - I’ll try that next.
The questions I have are…
Do I need to create a train that runs the layout in reverse order in order to get cars out of the destination yard?
If a car comes back to the yard empty, does it become a load again the next day?
EDIT to add that I tried adding a train and that did it. Still curious about empties to loads though.
