Leo,
I am confused as well but this topic is very important to me now that I am back to working on my HO layout and Savanna yard. If I understand this right:
1. Railroad A pulls a transfer to Railroad B's yard and drops them off. Returns waycar lite (nice touch BTW for modeling).
2. Railroad B pulls a transfer to Railroad A's yard and returns waycar lite.
Makes sense so far because each road will no doubt do their transfer at the most advantageous time for them to move the most cars over in one move (so will depend on their schedule for trains arriving at their own yard) and the railroad will try to move as many cars off their property to the other railroad to make the most of (or should I say least of?) per diem charges.
Now the confusion. What happens six months later? The only way I figured it could change was if:
1. Railroad A runs to Railroad B's yard waycar lite and returns with the Railroad A transfer cars.
2. Railroad B runs to Railroad A's yard waycar lite and returns with the Railroad B transfer cars.
Otherwise, it would seem the same thing always happens. Or is the 6 month rule simply that a new agreement had to be executed every 6 months as a matter of legality to keep the transfer operations going?
Does anyone know when this type arrangement ceased? Would it have been going on in the late 60's? Leo, do you know if this was the arrangement between the Q and MILW in Savanna?
Thanks for everyone's input on this!
