Silent transportation
I got a little annoyed at certain stations/depots making so much noise that the people in your cities become “sick” from the noise pollution. So I basically just copied the default buildings and removed the noise pollution. While this might not be the most realistic it gives you more freedom to place train stations and other transportation buildings wherever you want. I’ve also added a bit more light so they look slightly better at night (in my opinion). Building and maintenance cost is the same as the default buildings.
