Take a look at my photo in post # 6.
This is a TRANSHIPMENT PORT. A large area (fenced) with, among others, the CARGO railway station and the TRUCK station. In addition, there are also industrial buildings.
There is a bus stop in front of the entrance gate to the port, to which the bus stops from the city. The workers then walk through the main gate on foot, where they are then deployed to industrial buildings in the port area on buses that run only in that port.
I would like only trucks and not cars to enter this port (the entire fenced industrial zone).
I have many such industrial zones. For example, a power plant or other enterprises.
