I put one more industry in today, which is pretty much the end of what I can do with the track supplies I have on hand. I did finally get everything I need to finish the track ordered. Hopefully in the next week or so I will have a chance to make a push to get all of it laid. It is pretty cool to have enough track down to leave all of the locos and cars on the track all of the time and still be able to run a train around the mainline.
Updated track plan with what has been completed.
