Yes once the points are altered for DCC, the frog is isolated by removing the bridging wire and IRJ are placed on the ends of the rails, then the point blade rail is soldered to the out rail this i use the 32/0.2 for additional wiring with 16/0.2 are soldered to the outer rail and used to run the Points and Frog...

@Aviator

Aren't you running N gauge? If so, you may not need such heavy duty bus wires and point modifications may not need to be so extensive as we often do for OO gauge.

Default Infinitely vast, and growing!

Cheers for the response. So I need to make a clear decision right from the start on point control!
I think dc, as I'm going to make part of the layout temporarily dc just so I have something working then once the main board comes together switch to dcc (track only) for the big event. At least that's what I think at this point.
Also I quite like the idea of making DIY motor controllers (as in first post) and the led route map.
Can I even do this using the parts I've decided upon so far?

Another question I cannot find a definite answer for.
Dropper wire spacing.
What distance should I allow?

Yes. Confirm.
N gauge.

Dropper wires are ideally to every piece of track. However you can space them more apart, but then you rely on the metal fishplates.
16/0.2mm is adequate for droppers. You can use a smaller wire size like 7/0.2mm but then every section is dropper fitted and they are no longer than around 300mm rail to bus.
Frog feed wires need be no more than 7/0.2mm motor contact to frog as only the frog is being fed.

Droppers should ideally be connected to every piece of track.

I think I've got 5 on my 8 X 4 roundy roundy OO layout but its not ballasted, so I can add more very easily if I need to.

That simplifies things!
I had visions of needing to add wires every 200-300mm.
Mainly because most images show a ladder of wires being created!

Later I will upload my plan for wiring section A, for assessment and adjustment!
Cheers.

Default Second image

Based on my current understanding........
Droppers fed after each rail joint.

Wires only. For clarity.

I think I'll use 32/0.2 throughout.
As I'm unlikely to get through 100M of the stuff, might as well keep costs down?
(At least that's my way of thinking at this point!)


What happens with the open ends of the wires at the end of the bus run?
