Considering how much tension this flextrack is under, some day the glue might give out and suddenly arch a bunch of rolling stock into the wall.

I haven't forgotten my #HistScaleModels #HeaviesGB project but after meeting what I'm now calling The Anticanopy I'm backing up and regrouping.

Nicely fit. Canopies are why I bought two of the same kit. Or in this case, it's an anticanopy. This was supposed to be my "putty check layer".😅

OK, I went and test fitted the crazy Rokuhan flex track and feel better. The first pic was at an angle that made that turn look tighter. I think it'll make it. You can see how the bedded flex track has sliding plates & you can even use rail joiners. Picture that curving track turned to an S. Sure.

You might wonder why you'd spend so much time deciding where track goes on a model train layout. Because shunting's a fun t'ing!
So much fun I went ahead with the "testing the limits of Rokuhan flex track" project. Maybe I can "s" it in there, but if not just try something else. We'll see.

AI brainwashing complete? They only tell multiple sides to some stories, I guess.

Need some model railroading advice here: the "yard" needs a way for a locomotive to get from one end of a car to the other. I could put this turnout in at 1 or 2. I'm thinking 1. Switching out on the mainline would be kind of weird.
May wait a while though. Having enough fun the way it is.

Slated for 2029, the new Romancecar 7-car trainset features observation directly out the front and rear with the driver tucked up top. The Odakyu Line's 100th anniversary is in 2027 so think how far the rolling stock has come. prtimes.jp/main/html/rd...

One more model railroading question: I could cut the mainline oval here (at the bottom) and use flex track or trimmed pieces, but would this be too tight a turn?
Picture that bottom diagonal as an S bending all the way down to the image of the turnout. Would that add a lot to this layout?

Comparing the layout to the various shunting puzzles to see how they can be set up.

People kept saying "Z scale shunting is unreliable" but at the same time I saw videos of people doing it succesfully. One path that works:
1) *new* Rokuhan track carefully wiggled together
2) Rokuhan locomotives
3) Rokuhan freight cars
4) Reasonable speeds
When it works well it's SO much fun!!!

Opinions on switches. I want analog switches on the layout for the turnouts even if they'll get JMRI'd later. There's a spot here I had to clear to get access to rail or I could mount it on the side. What type of (momentary on, 12V 1 amp) buttons/switches do you prefer? One switch per or selectable?

Model railroad layout: where it started, where it's going.
It started on the first track, then it was shunted to the second.

Where model railroading & woodworking intersect? This feels too ad hoc to be wood working. Glue this in temporarily, then screw it up from underneath. Then more frame, spray foam, finally form and foliage, then it's a mountain/waterfall/tunnel but also a handle to make picking up the layout easier.

I just went though the exact same thing! I even used SCARM but when I really started putting it together it changed quick. Oh well, really happy with how usable it turned out. Really looking forward to seeing what you do with the subject of 70s Japan.

That bridge and elevated station still needs to go in, even if a lot of the rest of it like that big building and even that mountain on the right didn't survive first contact with the railyard's initiial construction.

For a model railroad rail tunnel with two tracks, if the tracks are two different types (metal color, ties) would it look better with a Robertson-style tunnel with two arches or one shared arch like the round or square entrance to the Jarlsberg tunnel?

Getting the wiring done with "superglue bolts" to fix wires in place. Helped a lot to use the right wire because for me stranded is easier to attach to track, and the stiffness or solid core wasn't workable. Achieved model railroading milestone of dropping all the turnout wires through the holes!

You have to see the outstanding work on this model train locomotive shop. About halfway through he starts showing the inside with the roof off, and the level of detail is absolutely remarkable. youtu.be/TQXE4Db4ZxE

As soon as I wire it all up I think it will be decent budget z scale shunting. Layout puzzles!

The RR's imaginary railyard design team is back and it's official. As one said "Track Don't Do That" (bending left around the base of the waterfall & back again into the tunnel in too short a span).
So the mountain has to go... up. Parts of it, at least. Opens up some interesting options or redos.🤔

After careful consideration I've decided "track doesn't run like that" (original green line). So, it looks like the whole mountain has to come up (red arrow). Can it just be raised up more with the new track running underneath? We'll see.
