Gary, Since you are not modeling either the BNSF mainline or the SP/UP mainline, you don't really need an interchange track. In the case of the LAJ the class ones drop off the cars detstined for the LAJ in one of the LAJ yards from what would be called an interchange track, but if it isn't modeled, and the yard is used as an interchange track it works fine, since what happens is the cars from the BNSF or UP just show up in the LAJ yard. By the same token cars from the LAJ destined for either UP or BNSF are delivered to the appropriate yard by the LAJ and in effect just show up in those yards as far as those railroads are concerned. Actually, I think the LAJ cars for UP are just shoved into a mixed freight of cars originating in the LA area and sent to Colton for classification. Likewise the BNSF just puts them in a mixed freight and sends the cars they receive from LAJ to Barstow for classification.
