You spend ages on you route getting it to look just right, then finding out that the industries you want to use, don't match the commodity's with the with the wagons you want to use! So it will not work, and you don't know enough about programming to get the wagons to use the right commodities, coming out from a portal.
		
		
	 
Catching up a bit late folks! PM CC'd for others:
Hi!

This is a matter of adjusting product ques or sub-ques  and allowed-product ques.
If rolling stock,  clone the version you want loaded coming out of the portal, Edit the  proper allowed products you want to add in the asset. Save as an empty.
Next  to load one, copy the clone to another folder, then edit that config to  increment or set the kuid, find the right load sub-container (governed  by the load kind, bulk, instances, liquid, etc.) and add the quantity of  the loaded car you want.
If an building asset, should be the  same setup, albeit in reverse. I haven't done one of those yet, but  based on analyzing the Trainz Wiki coverages and comparing to the CCG  there, can pretty much guarantee it's equally simple. Start 
here with the below:
| processes { | container | config.txt | industry | Processes (required) The input and output settings of the industry.  You can specify the amount of input and output for each queue referenced  product as well as the duration (or rate) in seconds for that process  to take place. All queues and processes are linked through the industry  asset’s script file. | 
| process-ID { | subcontainer | processes { | industry | User supplied identifier | 
| product-category | kuid | config.txt | product | Kuid of applicable category for this product | 
| product-id | ? | config.txt | paintshed-skin | For paintshed support. | 
| product-kuid |  |  |  |  | 
 
and readup on those tags and needs in both 
the CCGTC online  and by navigating the Trainz Wiki in the search bar. Titles in the url  can often just be typed, but need underscores to replace spaces in such  links of titles.
Good luck!
