I may add banking to the rail line, the only problem currently is that there are some areas around the tracks that are so build up that adding the embankment may mess some things up (or just take a lot of time install banking). I should point out that the pictures (esspecially the tunnel) are a bit out of date, the current tunnel and the area around it look a lot better. I will definetly look in to adding some banking, but it may be one of the last things I do, probably after the map's first beta release.
I am getting close to the point were I will add in the control points, at that point the map should be ready for testing.
