The BNSF Fort Benton Subdivision is a small 50 mile (approximate) branchline that runs from Great Falls, MT to Fort Benton, MT. Up until the late 1970's the line ran from Great Falls to Havre. However, do to unstable soils along the Missouri River, the tracks were pulled up just outside of Fort Benton. Nowadays, the line no longer runs into Fort Benton. It stops at the last of three unit-train grain elevators just a few miles south of Fort Benton.
My plan includes the small town of Carter, MT and two of it's grain elevators. I left off the unit train loader at Carter. Once through Carter, trains proceed to the 750,000 bushel EGT Terminal Loader. After EGT there is a small privately owned elevator at Tunis, before the train arrives in Fort Benton. My rendition of Fort Benton includes two grain elevator's, a co-op fertilizer dealer, and a team track/ramp. A reverse loop and 9 total staging tracks are hidden below the main layout and are accessed by a helix in the bottom right hand corner of the plan. Staging represents Great Falls, MT.
Several types of operations are included with this plan. Unit grain trains would be needed at the EGT Terminal Loader. The loader can handle up to 22 covered hoppers and three modern locomotives. Unit trains would begin in staging and then proceed up the helix to Carter and then onto the Terminal Loader track. After the unit train is loaded, the engines would cut off from the head end and recouple to the end of the train to take it back down to staging. The other type of operation of the layout would be a local freight, which would also start in Staging. The local would then proceed to Carter where it would switch the two grain elevators. After that the local would run to Fort Benton and switch the four industries there, before returning to staging. On the return trip the small elevator would be switched at Tunis. If I just want to run continuous trains, I have included a track that goes behind the helix and reconnects at Carter. Although not prototypical, I could use this to represent trains running to Havre, MT. Although the tracks to Havre were pulled up 40 years ago, in my fantasy world the tracks still exist and sometimes serve as a secondary line to reach the Northern Transcon.
I really like this tackplan because it includes my favorite modeling interests; BNSF, grain service, and rural Montana. However, one of the drawbacks for me is that there is very little scenery or topographic relief along, except where the line drops down into For Benton. If you've ever driven the highway that parallels the tracks you'll know what I mean. It's so flat up there, a person can watch their dog run away! The one drawback is that the trackplan does not have any engine service facilities, which is one of my favorites things to model.
