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.

Edit (jan 2019): Sorry I haven't been keeping up with all the new buildings they add with every expansion. I have made a quick guide below if you want to make a custom building that is not found in this collection. It's no more than roughly 5 minutes of work pr building. All you have to do is opne the building you want to fix in the asset editor and change one number in it's properties. That's it.

1.Open the asset editor. The theme you select doesn't matter. The asset will work with any theme so this basically only effects how your screenshots will look.
2.Select what type of asset you want to make, in this case "building".
3.Select the building you wish to edit and click continue.
4.In the properties tab (which should be open by default), simply change the noise accumulation value to 0.
5.If you want to make custom screenshots/thumbnail icons you can click on the "asset editor settings" menu (it's the little cogwheel icon at the bottom centre of your screen).
6.Click the cogwheel in your top right corner and save the asset. Name your asset and put something in the "short description" box if you want a more detailed tooltip to show in the game.
