I continue to make progress on my UP Council Bluffs Sub track plan. Much of what you see below is my initial ideas that have been somewhat refined from the original pencil and paper scribbles. I think I have a good mix of industries that will allow for a good mix of rollingstock. The I-80 bridge that you see on both sections is intended to help hide the seam between benchwork sections, and create a natural divide to give the layout the illusion of greater space and size. I decided to set it at an angle to break up the straight lines of the 16' table length. I have drawn in a second highway overpass on the far right of the track plan which represents HWY 92. I don't know if I will keep this. My reasoning for this bridge is to help "hide" the end of the layout, but allowing for future layout expansion if desired.
The yard area is still developing, but I intend to add a handful of tracks in a ladder configuration, plus a fueling track and maintenance shed if I have room. Although the yard design is being inspired by the IAIS yard, it will likely be a Union Pacific yard, with the IAIS having intermodal business only. This will still allow me to have some IAIS diesel power in the yard if I desire.
The left 8' section is also continuing to develop. I still have some space towards the front of the table that is unaccounted for. Some current ideas include a scrap yard, tank farm w/ loading platform, or perhaps swapping the concrete plant with a warehouse for the collection of boxcars that I currently have, which would put the concrete plant on the left front. The lumber yard space has been reserved but lacks any building detail at this time.
The plan is subject to change, but I am liking what I have so far. The various sidings seem to flow well, and allow for adequate space for a pair of locomotives and at least a couple of cars. I placed a run-around track in the middle of the plan for optimal operability. As part of a larger operation or a continuous loop, the mainline would handle run-through traffic.
Please let me know what you think.
