Operationally, I'm not seeing how you plan to run things (and first of all, no there is nothing "basic" or "unadvanced" about modeling a continuous run). People who are more seriously into operations (and that's an interest within the hobby, not the "advanced form" of the hobby, as someone has obviously led you to believe), have a problem with runni g (for arguments sake) clockwise to reach an industry, and then continue clockwise with the loads, deliver them, and then continue clockwise to the same industry again to repeat the process. At some point, the train would have to head in the other direction. But that's up to you and how you operate.
Do you intend to swap cars at your industries, or simply pull in, say, "Ok, we're here" and back out again. If the latter, no problem. If the former, you need to address the problem of facing point sidings (IOW, those branching off in the lime so that the loco does not have to reverse move to enter it). In a trailing point siding, the loco backs the train in, drops the cars, assuming no Caboose, and that the cars to be dropped are at the end of the train. If not, you have to move back and forth a few times to Hubble cars, but not hard. On a facing point siding, the loco gets buried, unless it has a place to run around the train and shove the cars in from the rear. The only place you have to do that is over by your yard, so you'd constantly be making unrealistic backing moves halfway around your layout to drop cars. Likewise with the passenger service. You need to back in to be effective, otherwise, you have room for about one coach plus a loco. It really only works if you're traveling in a counter-clockwise direction.
