Yeah, I'm inclined to put the onus on the Standard Gauge loco to de-conflict with the Narrow Gauge, based on my history that the NG was there first. And NG operations will be a lot less frequent than SG, so that's not a huge restriction.

Speaking of Operating restrictions, if the SG needs to pull a train out of the yard to do some switching, they'll be required to talk to the operator at the SG/NG crossing, to set the Ball Signal there for NG operations (which will block any incoming trains from the other room on the SG line.) :-) In the most recent previous photo, you can follow the SG and NG tracks to where the crossing is, just around the corner in the other room (just beyond that bottle of glue.) I'll position the ball signal so it's visible to operators in the staging yard, as well as SG/NG operators in the main layout room.

Id be inclined to fix it now before a novice engineer sideswipes a train. But we all have different priorities and I hate to see models damaged if it could be avoided.

Yes, you've come a long way. But only when we're both reasonably certain we aren't contagious.

it does look like you're having fun and it's is going to be fun to operate too.

HOn30 line is installed, rail joiners soldered and power feeds installed (but not wired to the bus).


I still haven't decided on that 2 track spur, but that can wait for later.


Once the track is connected to the bus, I'll try to drive a loco over it. (I got a used Kato N scale F3 as the test loco :-) )

A peek under the covers... There's a short section of HOn30 track between two turnouts, plus wires to the switch machines to power/switch the frog. Not installed yet are the power feeds for the switch machines (some of the parts didn't arrive as expected today...)


I figure when I'm done I'll do a full schematic, label the turnouts and track sections, and add tags on the wires.

Dave,

Strongly recommend that you start the labeling process as soon as you know this works, and well before Life Intervenes....

Trust me on this!

What Pete said! I see you went with the WAGO connectors.

The double-sided tape sticks much better to the plywood here than it does to the Masonite splines.

Yesterday I didn't do anything on the layout, I just read some books. Today I made up for that.


All of the switch machines (Tam Valley SwitchWrights) on the HOn30 line are now wired in.

I do have a color code for wiring, even if it doesn't follow standard practices (that's in part due to materials and in part due to starting some parts of the wiring before I saw some standards.)

The (Black or Grey) and White wire are the track bus. The wires taped together are for the HOn30 line (if they're not taped, they are the standard gauge wiring.) Track frog feeders are red. Switch Machine power (5v DC) is Red and White. The 3 wire cables are extension cables for the switch machine controllers.

Everything is connected together with Wago lever connectors. That way I can separate each significant wire from its source/destination.

There's still more work to do, particularly including checking and correcting the frog relays. On the right switch machine, those are the Grey, Red and White wires coming out of the screw connectors at the back of the PC board. Grey and White are connected to the power bus, Red to the frog wire. I'll power up the switch machine and check connectivity on the turnout, to make sure that the frog has the right power for how it's thrown. If not, I just switch the Grey and White wires on the switch machine itself. The other "adjustment" is making sure the controller for the turnout has the right indication. But that can wait for whenever I get around to installing the fascia. In the near term, after I get the switch machines powered, I can just have the controllers hanging loose in front of the layout. (Of course, before I do that, i'll have to check the connectivity on the full run of HOn30 track!)

So still more work, but at least the worst of the under-layout wiring and connecting is done. And I've learned how to construct Dupont connector jumper cables.

Dave, youve been busy. Remember, you only need standards for yourself and your layout. You can let the rest of the world have their own.

Nice job Dave, cut and paste that wiring description into your layout "user guide", so when you get old and can't remember, you'll have that handy.
