    Hey Ethan,

    I do like the MR plan. It would be difficult to use the staging yard without the lift bridge.

    Of your plans, I think it is generally preferable to avoid the operator being separated from their train by the peninsula, so unless just used for continuous run, or if you added tracks behind a backdrop for staging at the top, the second dog bone design would be better from the operator perspective. I don't know this part of the line well, but if there is/are places for interchanges with other railroads, you might add to improve the operations. Maybe MKT near Fort Scott?

    You might consider a design where the two yards connect at the top end a little further inward, and have a long return track with a backdrop/hlls hiding the staging, maybe at the top, or double track the return loops, hide them with trees/landscape and use them for staging.

    Anyhow, see you Wednesday. Maybe we can make this an agenda item for our breakfast.

    -Bob T.

    And in my experience (I don't have one) with friends who do have helixes is that if they are not absolutely perfect, they will be nothing but large headaches that are very difficult to maintain (to say nothing of trying to reach into one to retrieve derailed equipment).

    Yeah, having the train out of sight part of the time is less than ideal, but it was necessary to get the larger staging yard into the plan. I do need to keep looking at it on the track planner. I don't plan on doing any scenery at this time, as I'm 1.5-2 years away from moving again.

    So in my "era" (79-80, though I'm not very strict with it) there would be an interchange with the MKT at Ft. Scott, although I doubt there were many cars exchanged there by this era. The MP had abandoned all of their lines into town by this time, the Frisco picked up their industry trackage though. Beyond that, there were MP connections at Liberal, Lamar and Springfield. I had considered interchanged in these designs, but couldn't fit them in very well. The main way traffic will enter/leave the layout is to "interchange" with Frisco yards beyond Ft. Scott and Springfield via the staging yard. Most of my other plans I've drawn up, I do have the MP in Lamar, but I didn't quite have space for it this time.

    I'll be interested to pick your brain on it some more this week.

    And that is the exact lesson I learned last winter.
     
  5. Ethan, John Peluso has a very smooth helix. Maybe he will offer some tips if you do have to go that route.

    I went down this route last winter, and don't intend to go back to a helix

    Went back and looked at the plan again tonight and made some revisions. In this version, I shrunk the yards for Ft. Scott and Springfield, and flipped them over to the near side. By doing this I was able to add 2 longer staging tracks behind each yard to accommodate traffic to/from each yard. I had room for an additional track, but left it out for now in favor of leaving room for some sort of barrier between yards. The far back wall of the layout has a long passing track, I'm thinking I can use it as a holding track for some sort of run through like the NWF/FSE. since I got rid of the passing track between Lamar and Springfield, I found room to add the MP interchange that was suggested.

    True That! HOWEVER, The design and construction of any helix depends an several factors. Radius, slope (% of grade) materials, environment, research, etc. Prior to constructing my helix I spent a great deal of time in research on helix construction and weigh the pros and cons. The final result for my helix is it is very stable and reliable and have no incidents with it . The only time was a coupler malfunction and had a runaway train of a few cars that made their way down the helix at a good clip of speed without derailing.
    If you have to have a helix and don't want to engage in the effort to build one, there are company's that can provide you with a pre-made helix to fit your requirements.

    Made a couple more tweaks today to include an MKT interchange at Ft. Scott (Thanks to Bob T for the idea). Not sure how much traffic was interchanged here by 1980, but I can use it as a spot to change out a couple cars if I want to. This plan looks a little more crowded than the last. There is room for an additional staging track, but if I include it there isn't much if any room for a divider of some sort.

    Also, I made a 4th version that changes up the right side of the peninsula. Instead of the two coal mines condensed into "Arcadia" I have the MP Pittsburg Sub crossing and the Lipscomb Elevator at Liberal, and the MFA Fertilizer plan at Iantha. Haven't decided between the two versions yet.

    Update time:

    December ended up being busier than it was supposed to be, so I had limited time to work on the layout. A month after starting in on this new design, I finally began doing some operations last night. I'm still making some tweaks here and there, and still working on setting up car routing, but I'm getting there. I ended up leaving out the interchanges at Lamar and Ft. Scott for the time being. I also decided today to add two more destinations on the layout: Ft. Smith and Wichita. Ft. Smith traffic will be handled at Springfield and Wichita traffic will be handled at Ft. Scott since there isn't room at Springfield.

    I think operations will end up being as entertaining as I had hoped. It's actually a bit of a challenge to keep traffic levels balanced since there aren't any passing tracks to hold trains between yards.

    The pictures I took last night didn't turn out very well, so I'll try to get some better pics tomorrow night.

    Finally got a few decent photos to share.

    First shot is looking down at the Springfield area. On the left there are 3 double ended tracks that are used to hold cars for the local train and extras that don't fit in the main holding tracks at the back. There are 4 tracks, a spot for each destination outside of Springfield: (in order from left to right) Ft. Smith, KC/Tulsa (via Ft. Scott), St. Louis and Memphis. On the right of the picture is the three not so hidden staging tracks to hold trains at their off railroad destination. From left to right we have Ft. Smith, St. Louis and then Memphis. These tracks are double ended so I can run power from one end back to the other between sessions to bring the that traffic back to be resorted.

    Next up, we look at the town of Lamar, MO. Up front to the left is the Sunray Oil distributor. Behind that on the left is O'Sullivan furniture. On the right is the team track with TOFC ramp and Thorco. At the back is the MFA elevator.

    The final picture for tonight is the Ft. Scott area. It is the same yard design as Springfield, but the picture is taken from the other end of the layout to help give a different perspective. As with Springfield, the double ended yard holds cars for the local service and overflow from the main holding tracks. The holding tracks from left to right are for: Wichita, Memphis/St. Louis (Via Springfield), Tulsa and KC. On the right hand side of the picture is the not so hidden staging yard, with spots for Wichita, Tulsa and KC. The pair of switchers have begun breaking down the traffic that just arrived from Tulsa on train 38.

    That's strange. I assume you were logged in while trying to view it?

    I'll reattach them to this post.
