Wow look at the transformation! It’s starting to look great. Most photos for me too go the wrong way from my phone, I have to put them in the computer first. ____________________ Chris Teasel Bay Teasel Bay on Facebook |

Photos off the phone seem to post sideways no matter what I do. I have to persuade them to "forget" their origin (no doubt something in the code) and make them believe they came from a real camera. Those from the DSLR and bridge cameras never have this problem. The technique for phone pics is a slightly time-consuming upload via the computer to SmugMug and then downloading back to the computer before using the upload link on this site. Meanwhile the layout proceeds very slowly along and I have now to understand the wiring requirements for a piece of specially-built pointwork. This is a scissors crossover but with one of the four points being a double-slip diamond. It allows two tracks to feed three sidings with entry and exit available in any direction. Once that is working and pinned down the layout should be fully wired and working as regards traction current. The third rail for the passenger line will be a dummy; I have conducted trials aimed at having it live and used for traction feed but our various manufacturer's tolerances and scaling mean that the pick-up shoes are in entirely different positions across the brands. For a couple of metres of visible running line that was going to be too much effort for too little gain and the "live" rail will not be live. ____________________ Rick Layouts here and here |

I might need advice on untangling spaghetti. That should be accompanied by a bottle of Laughing Water of course. SWMBO is unwell and is due into hospital on Monday. This gives me a little time at home while she is recovering to both be close to her and deal with matters outstanding on the model without too much interruption. I have taken next week off work so hopefully will be able to make some progress. ____________________ Rick Layouts here and here |

An update. SWMBO has been home recovering from her surgery for a few days now and is doing well. She still has at least two more weeks off work. The layout is not recovering and lurches from short circuit to short circuit. In fixing the latest one I managed to cause more damage which means I now need to replace a yard of plain and ballasted track in addition to re-fettling the offending Y-point. I am going to have to get a diagram drawn because if I can't figure out what needs to be don I shall either tear out my remaining hair or tear up the track and try flower arranging instead. Over two years and the only progress made has been to move shorts from one place to another ....... ____________________ Rick Layouts here and here |

A diagram will be sorted. Would it be easier to just have a plain track diagram without showing where the feeds etc are and allow folk to fill in the blanks, as it were? ____________________ Rick Layouts here and here |

Thanks John and it's good to hear from you again. I seem to arrive at the computer on my way to bed every evening and therefore without the time to draw up the required diagram but I hope to get it done very soon.

Here is the mess I have got myself into. The first two are the wiring diagrams supplied with the custom-built crossover track which is shown as "A" in the track plan. You will notice that the diagram caters for a crossover with a plain diamond but the unit is actually a double slip not a plain diamond. I therefore have no idea how to wire it correctly. The colours used on the wiring diagram are as fitted to the track piece and all those which exist are fitted exactly as shown. However there are "doubled" or "piggy-backed" auxiliary switches (Peco PL-13 as per diagram) which is something I cannot get to work. They simply will not piggy-back with each other. The bar from the point motor is not long enough to go through two and where I have got them doubled up they jam the motor. At the bottom is the actual track plan with the position (as of today) where I have power inputs and IRJs. Clearly there is something not right because while individually most parts of the layout will work under power there remain dead sections through several points and both double-slips, plus there are numerous shorts which I don't understand enough about to rectify. All points are Peco code 75 electrofrog and all are fitted with PL-13 accessory switches except for the three-way which has nothing fitted, and neither do the points in the fiddle yard which lead to dead ends because frog switching here is not required. Good luck!    ____________________ Rick Layouts here and here |

Hi Rick Could I suggest that we take this in stages taking one section of simple trackwork at a time and leave the 3 way and diamonds until the basic areas are sorted. Taking this approach lets focus right now solely on the twin sidings and tracks leading up to the fiddle yard A at power feed 1 There are two points back to back from this single power feed.....It would be helpful if you numbered the points but for now lets call them A1 (top) and A2 (bottom) [1] A1 must be isolated on the ends (toes?) .....as shown there will be a short whichever way this point is thrown. I assume A1 has switched polarity? Check that this now works correctly I assume A2 is not switched and relies on the turnout blade to power the frog ? Personally I think I would have isolated the two points and added another power feed [2] Isolate all four ends of the diamond/double slip (?) leading to the fiddle yard A......we will add a separate power supply for this later [3] Sidings SA1 thru SA4 are now powered and should work without issue.....confirm [4] Add a power feed to the bottom siding SA 5 [5] Check trains will run from each siding on both routes up to the diamond. When you are absolutely satisfied this all works we can address the diamond or double slip Hope this helps......Nec aspera terrent ......my old army motto "Difficulties be damned" John ____________________ John Granby III Lenz DCC,RR&Co Gold V9 B1 Windows 10 |

Rick, I know you are a DC man so can I suggest you read this page for starters https://brian-lambert.co.uk/Electrical_Page_3.html it has basic frog wiring for normal turnouts, slips & scissors crossovers. I personally would not use 2 PL13's ganged but a PL15 twin microswitch ____________________ Ron NCE DCC ; 00 scale UK outline. |

Hi Rick, Did you want a double slip in the middle with a branch to the upper right, or a crossover (diamond) in the middle and a slip upper right? The examples I have seen are the latter. Crossover wiring is simple, basically continuity and isolation, that would have left the slip, which is straightforward. These assemblies are made from Peco offerings, so no real track building, just cut and shut. Or was this a custom build? Nigel ____________________ ©Nigel C. Phillips |

Nigel the crossover unit at "A" is a custom build using Peco standard pieces trimmed and wired as though it were three turnouts and two plain diamonds (one in the middle and one top right). I need the double-slip where it is, and it is a part of the module so cannot be easily changed, because I wish to have all five sidings fed from the top track and feeding the one immediately below it. Sol I already have that page saved and have read it couple of times. I also have Ian Morton's book Aspects of Modelling - Electrics which is a good guide but of course cannot cover every scenario. John I shall try to follow your thoughts when I have an hour or two to spare at the layout. ____________________ Rick Layouts here and here |

Hi Rick, So the slip is at B (which would correspond to the photos of this arrangement on the web and eBay). Missed that on the diagram  . 3 long points, 1 crossover, 1 double slip. I noticed you have live frogs in the diamond. Life is a lot simpler if they are insuls or dead metal.I would contact Mr. Nicholls to see what is wrong. Nigel ____________________ ©Nigel C. Phillips |

I was thinking of rebuilding the piece using insulfrog points but the chances of something stalling increase somewhat. I shall be running numerous small tank locos and 0-6-0 shunters for example.

Hi Rick, An 0-6-0 will usually trundle across insulfrogs or for that matter a dead metal frog as long as the frog is shorter than the wheelbase. The insulfrog design is different to the electrofrog - around 2-3 sleepers for the insulfrog, around 7 for a large radius electrofrog. Can you get insulfrogs in code 75? If you are rebuilding it's worthwhile shortening the distance between the closure rail and the frog. Nigel ____________________ ©Nigel C. Phillips |

Rick/Nigel I have used insul Code 75 crossings and they work fine without any hesitation with 6-coupled tank engines. I don't have any 4-coupld so cannot comment. Barry |

I'm not at the stage of rebuilding just yet. Despite one loose blade on the double-slip which I'm sure can be dealt with it remains easier to my mind (and with an amount of collective support and assistance) to sort out what I've got that to start over.
