Wiring 40" x 8" shelf layout
« on: March 06, 2016, 07:37:43 pm »
Here is my shelf layout plan yet again:



I will be using electrofrog points, so would I need to use isolated rail joiners? I want to use the sidings to keep locos at times. If I use IRJs I would, presumably, need to wire the rail that is now isolated beyond the frog of the point.  However, this would mean the track is live all of the time.

So, how would people go about wiring this small layout for maximum operating potential?

 :thankyousign:

Using your colours to separate areas,  I think you need one more coloured zone.   The cross-over in the blue to the front, under the two green lines (road bridge?) needs separating, so the line at the front labelled "shunting" is a new colour (call it "red" from here on). 

Then, the joint between each coloured zone should be insulated joiners (both rails).  Power feed to orange should be below the "S" of "Shuttle" and to blue above the "u" of "Shunting".   Green powerfeed along the straight to buffer.   And the new "red" area power feed would be on the straight to the buffer at the far right of layout. 

In terms of isolating locos, the turnouts would power-switch sidings of the same colour, but you might want to add further insulated joiners (in one rail) and separate switched power feeds to the single rail in parts of sidings to allow more loco storage.

Thank you. 

So, I'm using electrofrog points,  am I right in thinking I don't need to use IRJs for the points that are sending locos into sidings (e.g. station platform)? and the point switching will isolate these sidings?

Providing there is a feed to the toe of the point (where the tiebar is) there is no requirement for IRJ within a siding unless you want to create an isolating section in the siding e.g. in a loco shed.

Thank you,  so the point acts as an isolator and only feeds power to the track in the direction the point is switched to? is that right?

It does that on all my Peco code 55 electrofrog points :)

That's good news, should do it on mine as well then! :D (code 80 though) :thankyousign:

Regarding your post just before NPN's above:

Not quite. If it is a dead end siding, then as NPN says, the only gaps you need are if you are going to park multiple locos on that siding, so you can just switch them on and off.

The problem lies with loops.... where there is a point at the other end offering a run around.  Then you will need an irj because the polarity gets reversed and without an irj you have a short circuit.

The Peco instructions are pretty basic (unless they've changed), but are sound.

Thank you Bealman, my plan doesn't have any run around loops and is a very basic, small, project.  I think I have it clear in my mind now.

Many thanks for your help.

I'm pretty useless with 'Paint' but I have placed feeds and IRJs on your plan as follows (black triangles for feeds x 4 and red bars for IRJs x 3):-

Thats pretty much what I had worked out.  I also think I will put some isolated sections in the sidings.

The fog is slowly lifting...

After a long while I'm finally going to build this layout. 

I think I am going to protect the hidden sidings using a gap in the track and a diode,  my questions are;

Is there a particular diode that I need to use? 
Does it matter which side of the track I attach it to?
How do I know which way round to put the diode?

The most common ones you're likely to come across are the 1N400X series - most likely 1N4005, though any of that series will do.

Does it matter which side of the track I attach it to?

No, either side will work, but the diode will need to be oriented the opposite way for one side of the track than on the other.


How do I know which way round to put the diode?

Easiest way is to just test it - wire one up, and if it doesn't work, swap it round. You can't do it any damage, and you've a 50/50 chance of getting it right the first time... :D

Hope that helps,

As things stand the two sidings at the bottom have very restricted access and will add little to shunting operations. Why not connect them up to make a run-round loop?

The plan has changed in the bottom right part of the layout.  It is now going to be an inglenook puzzle.
