>is it just the list that is incorrect or are the cars actually on the classification tracks for those initial trains before the trimming is done which means the cars have to be moved to their correct class track after trimming?

The cars have been previously classified to their correct (listed) classification track. And they (hopefully) are on the correct track (for that classification.

The issue is that -subsequent to the classification- the Car-distributor ran, and re-routed the cars.

~~~

This is why, as Howard pointed out a few years ago, we need the "Yard Switchlist".  To show which cars have been re-routed by the car distributor.

>trim all trains with one command 

The "Setout and Trim" command is intended to report that that one block-of-cars has been re-classified in the yard.  That is, to tell the computer that an action has been completed.   It is similar in its effect as the "Pending".

What did you see the Trim command as doing?

I admit that I am at loss on how to respond.  Please let me try:

>I would find cars misrouted on the wrong trains only in the yards

a)  The cars are not mis-routed. 

As explained many, many times the cars have been loaded/re-assigned by the Daily-Summary car-distributor.   As a result those cars are now (more than likely) going to a different destination.   That destination is served by another train.  That train is classified to on another track.

Howard pointed out this issue and now we have the "Yard Switchlist", which lists which cars should be picked up and where they should be placed.

We talked about this during the past Weekend.

b) >You advised me to individually "Report" each train, "Open" it and "Trim" it

What I actually said (years ago) was that you should, before printing the train-consist, carefully look at each individual train, looking for cars that are routed Same-Yd to Same-Yd (current location to next location).   Then, only if there are re-routed cars, only then "report" and "trim" the train.

The problem is that you "lose sight" of where a re-routed car went.  (There is now a disconnect between where the car is in the computer and where it is on the railroad).    We now have the window/list under Yardmaster which lists classified cars.   You can also use this list to re-classify cars.

c)  When you click "Set off and Trim" the program re-classifies every car in that train.  Most cars (those not re-routed) are re-assigned to the same train (simplifying the issue quite a bit).

It is manageable to handle the re-direct cars for a single train.

However, with a single button, every car in a yard would be re-classified.   In your case hundreds of them.   Can you imagine the mess it would be to sort that out?

d)  If the operator prints a train-consist list "as is", which re-routed cars (Same-Yd to Same-Yd) either operator will catch it or the yardmaster will catch it and the train-crew will certainly catch it (during their roll-by).

The Operator "trims" the train, reprints the train-consist _and_ prints the "Classified cars" list for the Yardmaster.

Is this really that big a deal?
