This is an edit of the map "gm_fork" originally made by "Blueberry_pie."

Now as the name implies, this edit is mostly a train focused edit. In the original version the sample railroad track size was very small and didn't even loop. It was mostly just a straight line with abrupt end points in the tunnels. So the 2 tunnels now reach an upper area of track in the mountains for a nice scenic look and they will loop back with one another. I tested the new tracks with SligWolf's variety of train addons and Neb's Thomas addon.

And it worked for the entire journey up and down the mountain (Be carefully when going around curves however, don't go TOO fast or else you might de-rail). Now I couldn't compile the map on the Normal setting sadly because my PC is poop. So I did do a few minor optimization changes. Mainly changed the fade distances on certain props, and got rid of some unnecessary props i.e. tree clusters, rocks, and vehicles. Anyway, I hope you enjoy with all your train related endeavors. And if you notice any issues let me know so I can fix them!
