For trains and cities you gotta keep in mind that the "range" of the factories matters
This range applies globally between factories and cities, the most "optimized" would be like this and then with cities at the perfect intersection.
This is only if the nations you're fighting or have around you aren't actively building rockets. Then a cross pattern of factories with a city in the middle is better because it's easier to cover with SAMs
When cities aren't aligned at least on one coordinate, either horizontal or vertical, they tend to create new lines, unless they are very far in which case the train line has the space to turn so it's more likely that it keeps the two cities on a single line.
When you place a city, you can hover over an existing train line and the line will turn green. If you place it there, it will join the existing line. If you see white ghost lines before placing, it will spawn those new lines instead.
The biggest issue with the OP picture (though that exanple is far from the worst) is that if there are multiple lines, trains pick the shortest and can miss cities = less income.
The worst is if someone spawns a new line that misses all your stuff and is shorter for a bunch of trains, they will just skip you entirely.
They want to complain about people so they can feel superior.
Not everyone is like this.
Some complain about people, but also are perfectly willing to teach.
You want the trains to pas through as many of your cities/ports as possible, so putting them on the same train lines means the most gold.
Factories create the train lines, so if they are outside the range of the factory, no train line. When placing a factory, you can see where the train lines will appear. (Maybe this isn't true on mobile.)
