Advice on this Loop.

[Aussie 3 railer]

Hello All,

Been a while since I have been here. Renonations and and a spot of ill health slowed me down.

This current layout is one of so many other numerous layouts I have tried. Most were done away with for one reason or another. Peco must have been very happy with my efforts with the track I have bought.

My problem with this one, I actually really like, is this loop which is beyond my expertise. I have included a mud map for reference rather me trying to explain as Brian suggested some time ago.

My problem is between points B and C in the diagram. This is where the polarity changes for my bit. The distance between B and C is about 900mm plus. All my rolling stock have or will have plastic wheels so I am figuring no shorts here and plus none of my trains will be multiple cars.

I have a few options here but my preference would be to use NO / NC contact switches as a means of wiring a possible solution. I am waiting on DCC Concepts to start production again on the Cobalt SS point controllers..... I have a couple of IP Digital controllers I was initially going to usevuntil I saw the Cobalt SS controllers. So depending on your advice I am happy to use them temporarily for the moment or whatever. I have an idea to use them above board.

At this moment I will be using manual point conrols while I wait for DCC.

In my spare time I have been making my own points after encouragement by Rick of DCC. I have learned a lot and learned not to paint the sleepers and to stain them. Found it very rewarding and to date all have tested out rather well.

Hi Aussie,

Since you are building what looks like a reverse loop, you might find the information on the following link, of use.

if you are unsure, Brian may be able to provide further clarification...

Hi
Here's my take on the reverse loop. However, a lot depends on what happens track configuration wise after point C? But without that detail then.. Use six Insulated Rail Joiners (IRJs) a pair being fitted where I have shown each of the red lines cutting across the track (3 sites in all) The pair of IRJs on the upper track after point C can be pushed out much further along that track if wished. Feed the rails between the IRJs from a changeover pair of contacts - A DPDT Toggle switch is simplest, but you need to remember to flip the switch as necessary. Of course DCC is much simpler by using a Reverse Loop Module for the feeding of the section between the IRJs.


BTW don't rely on all stock having plastic wheel sets, ideally, these need upgrading to metal wheels. But also you may in the future obtain a new item that will have metal wheels anyway!
