Default Wiring Diagram

Hi all,

Here is my first attempt at a wiring diagram. Please don't laugh too hard, ok?

1 I've gone for wiring every other track piece because it's only a small layout, I think every piece may be overkill.
2 I've also made sure each point is powered, and the ovals are separated by insulated joiners.
3 I'm going to use a Gaugemaster D twin controller, hence the 2 bus wires. Wiring will all be the same colour, I've just changed the inner bus colour for clarity.

Thinking behind isolating sections
1 The two sections on the outer siding are so I can park two locos while still running mainline ops.
2 The inner siding will lead to a goods shed, so I want to be able to have a loco unloading and be able to switch mainline ops to the inner loop.
3 The bottom isolated section is so that I can park a passenger train while I use the top points to move a freight loco to the outer siding.

Questions:
1 Is it logical? I.e. does it make sense, or will someone think "WTH??"
2 Have I understood and wired the isolated sections correctly?
3 Will it work?? Or will I fry everything the moment I turn it on??

Any comments, criticisms or suggestions welcomed.

Like I say, it's my first go, so be gentle...

I see nothing wrong with that as a starting layout. As you expand , then cab control make moving trains easier.

Are the first IRJs on each siding going to be on both rails?
I ask because, although you are powering both stock rails on the point, if you have an IRJ on both rails you are relying on the contact between the stock rail and the point blade to power the rail up to the IRJ. Since you only need to isolate one rail I would leave a normal metal fishplate in the inner rail of the top siding so you are feeding power from both ends.

Other than that I can't see anything I'd change.

Good luck.

Good point, never noticed that. Looking at it, on both sidings there is a section of track after the point but before the IRJs so I may just add a track feed on each of those sections to ensure full power flow. Because they are insulated frog points, this should solve that problem, or am I wrong?

It would solve the problem, yes.
