Industrial area of Edinburgh and Lancaster
Edinburgh is the second largest town on the map, it has now ~860000 inhabitants (in the game), and Lancaster is a smaller town with ~40000 inhabitants.
This industrial area provide most of the goods for the two town, including cars (not seen in picture), ethanol, gasoline, furniture, concrete, planks, books, etc.
The wind power plants and the oil-fired power station are giving 18000MW power, which supports the factories and the cityes too (i'm playing with experimental).

Two passenger metro lines and a trolley bus transport the workers to the area.
The finished products go by trucks into the cities, and ~5 ship lines in canals.
