Right now, any car that goes 'off layout', for any reason, will return, at some future date, as either a load or empty, depending on what's needed on the RR.
So, if I understand your question correctly, the answer is both yes and no. The car will return, but it may be a load (for some other industry) or an empty.
Right now, there is no “when empty return car to”, but that’s on my list of stuff to do next.
Actually, there are three types of owners of cars.
1. Local Industries, i.e. PFI and Bennet Lumbar
2. The branchline that I am modeling, the Washington, Idaho and Montana Railway Company
3. The big boys, the GN, NP, MILW, and others.
Actually, there is a 4th type, off site local owners like Willamette Industries.
Just to confuse things a little…
