TG,I am using the carcard/waybill system that Doug Smith introduce back in 62 or 63..Its a 2 step waybill..Either a load or empty in and a empty or load out.No waybill means a empty and it can be returned to the yard or the nearest interchange as per the instructions on the carcard.Like this:
ATSF 29102
When empty
Return to Agent ATSF
Bakersfield,CA
Via reverse route.
That tells my crew the empty will go to the yard.
Now if it says this:
CR 220778
When empty
Return to CR
Via nearest interchange.
That tells my crew to leave it on the CR interchange.
I like this system since there is less writing to do..LOL!
