So the main idea is as following: you start out at your home, in this case a 5 track shed. you can see the end of the yard which is walled in the back. you cannot go out on the mainline line because the tracks near the tunnel have been worn and broken. Your only way out is through the tunnel leading to the main terminus on the left. (nexus) this area will have an entrance to all 12 branch lines, your goal is to collect 24 pieces of rolling stock. These can be open wagons, vans, flatbeds, engines, ect.
Now, I know that starting a game an announcing here so early on is irresponsible, however, this took me like, 1-2 hours to do. I doubt the rest will be too much trouble.
The engine I have chosen to represent the player in the class 08 diesel shunter. Small and slow, just like Madotsuki. you can later find a class 03 diesel which is smaller and faster on one of the branch lines, much like the bike effect. if anyone has ideas on what loco she should be, I'm open.
