This is not aimed at anyone in particular, but is a general observation.
I think I have noticed a trend lately from people asking for help on designing a track plan for a new or first layout. This has nothing to do with the amount of room (or lack of it) that a modeler has for their layout. They want yards, engine facilities, industries, towns, etc. that are typical on many layouts. However, they don’t seem to know how to go about it. I think one of the very basic pieces is missing and has not been pushed very hard in the model railroad community. Now, the operation guys and people that already have layouts may know the answer on a subconscious level. Are you ready?
People getting into the hobby or starting a layout for the first time are looking at running trains, but may not really realize that the railroads are a major transportation system. Trains have been around for a long time and have become commonplace. Because of that, their basic purpose has been in the background, so to speak.
The railroads basic purpose is to deliver goods from one town to another. (From industries in one town to industries in another town, and across vast distances.)
So what does this have to do with track planning? I think that basic track planning should start by trying to run a train from one town to another. Then, in each town, a couple of industries (shippers and receivers) or more, depending on the size of the towns and your layout space. OK, so what if you don’t have the space for two towns? You try and work your track plan around one town as best you can. If you have to ship from one industry to another in the same town, so be it. But now that is where our imagination comes in to play. We can pretend that shipments are going between two different towns by making up a train in our town, running a couple of laps, then bring it into the town again (pretending it is a different town) and set out some cars.
But the point is, simulate the railroad as a major transportation system as
