Updating Fort Smith to Heavener

I am working on a project to learn to use the route building tools. I am updating the graphics to the Allaboard Fort Smith to Heavener route. I am using Soldier Summit for the track rules. I have no idea how long it will take me to finish this route, so please be patient and not bug me about when this will be done. I am taking a full load of classes working on my Bachelor's, so studies will be my priority. I have felt that this route needed to be updated as the trees look very flat, the tracks could use some touching up, get rid of some of the outdated rolling stock, and make it single track to replicate the real life KCS Fort Smith dodger line. I still have a lot to learn, but I have started by replacing track, road, and crossings in Van Buren at the north end of the route. Here is what I have done so far. I am thinking about adding Peninsula Corridor for the gantries and rail crossings.
