This is the industrial wasteland city I was talking about in the post about Thaylambar.
Click image to view full.No one lives here. No one would want to live here. In fact, no one could live here. Not with the levels of pollution in this city. I suspect everyone who works here has to wear a gas mask and breathing apparatus to work. Many coal power plants are scattered throughout the city. Industry requires a lot of electricity, and coal is nice and cheap... And dirty. All the other cities in the region buy their power from here. They also export all their garbage to Mithral to be incinerated. You can't see it in the picture, but there's a toxic waste dump in the city for nuclear waste.
Most every Sim in my region commutes to and works in Mithral. There is an overly elaborate rail system to get everyone to work. The elevated rail system is tied in with the heavy rail system. The mass transit fares alone bring in enough money to cover all of Mithral's expenses. It would be a hell of a city to ask for directions in. I purposely made the road and rail network chaotic; it adds to the dirty look of the city.
A lot of time and effort has been put into this city. The whole city is like a giant puzzle trying to get everything to connect together. It may not look it, but it is the gem of my region.
