let's start by doing one car, because that works ok. five days a week a box car full of widgets has to go to the autoparts factory. it's coming in on interchange. the layout has 'portalinterchange', 'local' and 'ecs'.
Here is the worksheet from the manual
Industry Analysis Worksheet
Here is a sample format for a worksheet I use to create the Industry Analysis. I just do this on a lined yellow tablet. I put the heading on the first page, and after that it just comes natural.

the record would look like this
cmtm0 "12345xx,Portalinterchange,XBG,x,APF 1,load,widgits,3,????,empty,x,x"
In english a boxcar will arrive on Portalinterchange destinted to autoparts factory on days 1, 2, 3, 4 and 5. This boxcar will be loaded with widgets. After it has been delivered, it will take 3 hours to unload. Then its destination will be ???? as an empty car.
Now, if you place a boxcar on the track where the "Local" trackmark is located, this record should be assigned to that car. It can be any car that has a category-class of XBG. This movement record will be used once.
If you do not put a boxcar on the "Local" track, this record will be assigned to the first boxcar the is emitted from the Portalinterchange.

PS: CMTMSystem2 assigns movement records in the order they are found in the config file. CMTMSystem3 has added capability where you can specify that a movement record will be used at a specific location or for a specific train that is emitted from a portal.
