Im not really good in explain somthing, so sry if it is really hard to understand.
You will find the pathfinding in the mdl data. form the cargo station. You will find the cargo tation in res\models\model\station\road\
You will now see the orginal code from the medium_old.mdl. I try to explain what is what with this code.
Code

end of the alternative
{ 2.0, 12.0, .0 } this is the end of the alternative. This you can also find in the main line
The alternative will be used by going and returning from the stop to the street passing other stops.
Starting point of the alternative route
{ { -2.0, 12.0, .0 }, { -7.0, 7.0, .0 }, { -7.85, .0, .0 }, { .0, -7.85, .0 }, 3.0 },

{ { -7.0, -5.0, .0 }, { -2.0, -15.0, .0 }, { 0, -1, .0 }, { .0, -1, .0 }, 3.0 },
end of the alternative route
according to this, as can be seen in the game, the little cargo station has one main line, which goes over both cargo bays and 2 alternative routes which results in 2 separate lines.
