After reading the topic Adding "Custom" loads to OpsPro - Part Three, I had setup two spurs with a schedule for a reefer to receive MTY and? ship FROZEN FOOD.
Did you actually have two Spurs using the same schedule for the MTY refer? And on each of them, you left the "Destination" column blank?

I then had a reefer on one of the spurs shipping FROZEN FOOD and its load was MTY.
How did you get this refer into the Spur and it remain MTY?? The program would have converted the MTY to a load of FROZEN FOOD when the car was spotted at the Sour.? If you placed it manually and then told the program NOT to apply the schedule, that is the only way I know of that would have left the car MTY.? If you misunderstood the sequence of load conversion from my article's instructions, I apologize.? If you read down through the whole article, I wrote...
Remember, the schedule is applied to all the cars as they arrive at a Spur, not as they leave. ?It is key to the process, that the program be given defined "instructions" so to speak, and will carry them out when the next check for assignments occurs (when a train is built).
This occurs when you build the train that delivers the cars to the Spur in the first place.? The schedule of the Spur is applied when that train terminates (or is "moved" beyond the location of the Spur).? Thus, if you have Train#1 that services the Spur and it has a refer listed to set out at the Spur, the schedule will act upon the car when Train#1 terminates.? Then the car will remain with its converted load until you build Train#2, at which time, the assignment check (for a destination) will occur and the program will try to send the program on to the stated destination.?
You wrote...
...according to Part Three, the system should, on building a train, apply the schedule and do two things, change the load to FROZEN FOOD, and find a spur to receive FROZEN FOOD and set the car to go to that destination.
I fear you are mixing up the actions of the schedule and the program's choosing a destination.? Or at least, misunderstanding how many trains make the process work.
So, again to be clear, when Train#1 is built and delivers the car, the schedule is applied and when Train#2 is built, a destination is assigned, which the program tries to route to the new destination, using the second train built.

Again, you wrote...
However, when I build the train to move the car from the yard track to the C/I track, the resulting move is to another C/I track, and the final destination is removed.
If the program is removing the final destination, this indicates to me that the route is broken somehow.? When you built the train you expected to set out the car at the Spur, did your Build Report have any wording similar to this...?
- ? ?WARNING! Car (UP 47417) at (Midway, cattle yard) can't be routed to (Midway, StockYard-(custom) will?
? ?attempt to move stuck car?
This might mean the program isn't able to route the car properly and is attempting to reload the car in order for it to then be moved.? The program is always seeking to move cars and if it thinks it just can't deliver the car anywhere, it attempts to reload with something it CAN deliver.?
This is why I also mentioned in the article...
Once a car is assigned a destination, unless there is simply no route to the final location, the program will send the car to its target.
Now, since you mentioned in your post, that...
On checking the Build Report, I can see that the final destination is currently unavailable due to the fact that there is another reefer on that spur.
This alone should not cause the program to replace the load.? It should just find another track on which to wait (if no "alternate" is used).
As Dan notes, the behaviour is not expected and the Build Report will shed light on the actual issue.? Can you post the train's BR here on the forum and we'll take a look...?
?
I would also suggest a pencil-to-paper approach to sketching out the movement of the car between the Spurs involved.? Check the trains involved, any intermediate tracks you think should be used to facilitate the movement, and the final tracks (the ones with the schedules) used to set out the car.? Sometimes, this lets you see what you might have missed if you are only looking at computer windows stacked on top of each other...
