Cool - Making great progress.
What’s up next?

Staging level covered. Drawing out the tracks for staging and contemplating the operations I want to do and how I want the trains to be organized. With three tracks coming down the helix it will be interesting. On the wall shelf there is space for 8 tracks. The Birmingham lead will get two, and Sheffield and Memphis will get three. In my head I am calling these arrival and departure tracks. One track for each will be the through track that will go around the blob and connect to the other end. Memphis and Birmingham will connect for continuous running. Sheffield yard will run around to itself for sure with potential to connect to either Bham or Memphis. There is room for about 15 tracks in the yard portion. They will all be plenty long for the 8ft planned train length. With the arrival and departure tracks I should have staging for about 17 trains. Double park the shorter locals and in my head that should give me plenty of space. I will probably drag out some locos and cabeese to stage some pretend trains and run them out. At a friends he had a point to point with 8-9 tracks at either end and each train simply exchanged tracks with the train headed the other way. With an operating session going  probably having 4 through trains and 1 local on the layout at any time would probably be about the normal load. 7 would require some slim operators. I am going to use code 80 in staging. And it isn’t available anywhere I can find at the moment. Well I still have to get the floor in so track will be something I am keeping an eye out for. Now turnouts are another story. I liked Peco in my Ntrak modules for the easy manual throw. In staging that wont be easily possible so some sort of machine will be needed. So if one is using code 80 and either electric or manual remote(blue points?) which turnout do you use?

I put up the upper deck around the outside of the room. I teach and with our 2nd collision with covid about to happen progress on big things will slow mightily. So playing with the upper deck structures bridges and the top lighting valence will be the primary modeling for a while.

Swapped the door around to open out and started playing with how I am going to cross that gap. Swing bridge with FreemoN style ends is up first.

Looking good!
You can use Peco turnouts in staging, remove the spring, and add the motor of your choice.

That is the plan at the moment. I have a lot of reclaimed Peco turnouts from my Ntrak days. Also Peco seems to be available whereas Atlas does not.

So with some recycled foam down on the top level temporarily I rolled out the 1:1 paper plans and started to have a look at how the elements I drew would actually sit on the layout and how they would mesh with each other. For what I have up there are three scenes that I want to have in there and replicate them pretty faithfully. Top on the list is the crossing at Old Memphis Pike west of Tuscumbia. This is where I spent a ton of time either in or sitting on the hood of my grandfathers car watching trains. Next is the station in Sheffield. Never active when I was there(last passenger train was 67 or 69) it was a great place to watch trains go by and listen to my grandfather tell me about the shops that used to exist just the other side of the tracks. Dating back to the days of steam it had a full roundhouse, car shops, and loco servicing. By 71 there were only two buildings left, the car shop building and one of the backshop buildings. In the next aerial I have in 78 its all gone. I am going to model the car shops serving their last days with that backshop building being torn down in progress. Pulled up track, rotten wooden boxcars, maybe a HW wood car on the ground. The new Sheffield hump yard is open, rolling stock is made by subcontractors now and the facilities department spends most of its days removing the past and cleaning up the mess.

The last is a couple of sheet metal cotton warehouses in Tuscumbia that had rail run into them. I never saw a boxcar over there but my grandfather said they used to load boxcars there regularly. It will get regular service on my layout. There will be spots for 2 40ft cars.

So I moved things around on the plan a bit until the looked ok on the foam. Got out some old buildings for sizing. Lastly used a bunch of ME flex to actually lay down track for a look see.  Got carried away,(surprise) and layed out every piece of code 55 I have. Since I was already going over the top I broke out some rolling stock for a look. Train length is aimed at 3 locos, 20-22 cars and a caboose. With one train at 4 and 20 and the other at 3 and 21 this looks like it works out well.

Around the wall lower deck is roughed in. This will allow the lower deck door crossing to be completed. Starting to plan blocks for detection and signaling. For operational ease I am adding a set of crossovers on the twin mains midway down the section where the old Sheffield station. In real life there are none but for the things I want to do with passenger trains and my train lengths I will be changing that aspect.

So playing around with staging design. There are three tracks coming down the helix. One is Memphis the west end. Middle is Sheffield yard and points east, and the third is Birmingham and points south. There is an AD area that is along the wall. Each track coming down the helix spreads into three tracks. Those three extend at least 8 ft and then transition to the main staging yard. Some tracks go straight through and some branch. I stick with tge original 1-9 designations and additional yard branches get a prime tick on their originating track number. The outside tracks balloon around the penninsula , 6 and 5 attach to the inner balloon. They could get their own balloon track, I just thought of this. But basically there will be a balloon track that any train coming down the helix can access if necessary. Gives space for 22 full trains, 3-4 locals and potentially 3 more full trains in the balloon tracks. So potentially 28 trains in staging. That should be enough for a full operating session if I get it to that point.

So I got home and I had a package from Ebay waiting on me. I got the Kato through truss. I pulled the deck off and cut the ends vertical. I looked at the picture and using a divider measured the kayak. I think most are 12 feet. Using that measurement the bridge is 150 ft. If the kayak is 10 ft the bridge is 120 feet. Either way I could get a good measure of the height above the water and the vertical height of the bridge. In order to figure out how much clearance I am going to need to create with a drop in benchwork or some extra foam on top. The Kato bridge is 120ft long but it is too tall by about 8-12 ft. I am not sure I want to chop the height out of this bridge. If I do I will effectively be rebuilding the bridge because I will have to change the angles of the cross braces. Once you get to that point you might as well scratch the whole bridge. I think I will shorten the piers and install this bridge. When the layout gets further along and I am looking for projects I will scratch build the actual bridge. I know that is probably 4-6 years down the road. But to signal this thing like I want to I will be spending a lot of time scratching D type signals. Those are further up the list than a correct bridge. Especially one that I have personally never seen. Now the next bridge is one I have viewed many times and fidelity will be much more important to me.

I feel you.....
Life would be soooo much easier if the Kato bridges had just a bit better proportions.
Making great progress, btw!

Thanks Michael. Played this morn for a bit with the Spring Creek bridge. Cut the outer edge of benchwork for the creek bed. Glued in a piece of 1/4 in ply for the base. Cut the foam to give a shape to the banks. Then put in a flat piece that will have the abandoned trolley roadbed on it. Placed the bridge in situ with tracks just sitting on it. I think the approahes are deck girder. I have girders from another project that will probably work. Also played around with some landforms to create some elevation at the Memphis Pike crossing. The tracks are decidely higher than the road that parallels them. I used dividers to measure the houses that will be along the road east of the crossing. Based my measurements off of the door widths. Using those came up with what look like reasonable measurements for the three houses that will be there.

Did some calculations and figured out there will be over 100 sticks of flex in the helix and a similar number in the staging yard. Save up!
