- In this video I show how I have laid down the third track for the new layout and talk through some issues I have had with power shortage on points. If you have any advice or just want to say hello please leave a comment below.
Good morning Steve! Great to see three trains running! You're making some really quick progress! Not sure what the shorting problem can be so can only advise on checking the usual suspects - loose wiring / trailing wires / loose point blade etc... Good luck in tracking it down, and keep us updated! I like that you've built in a triangle to be able to turn locos around! All the best, Ian.
Morning Ian - Yes I am methodically going through all that but as I said to Stephen I am having some success with a bit of cleaning but if all else fails I will swap out the point itself. The weird thing is it only happens every three or four circuits, and very randomly - the problem with re using old points I feel.
Regards
Steve
Bet you’re happy now nice sunny day Trains running looking good Steve cheers al
Oh yes - I can sit happy now with a brew and watch them go round ... just a few small issues to sort out but yes I'm getting there. Cheers Al

Hi Steve - excellent progress in the build. I do like the double track winding it's way up the gradient - looks a gentle gradient. Plus a running session to boot. Cheers Euan
Thanks' Euan - my favourite moment is when I see both locos on the upper track and one passing under neath - if only I can capture that on video!
Regards
Steve
Greetings Steve 🐲🏴👋 You must be delighted to be running all three lines 😁 testing is the fun part 🚂 Stephen has offered some excellent advice regarding your shorting issue 😇 those n gauge bogies will find every opportunity to spoil your fun 😱 Very best wishes from the Emerald Isle ☘️
Hi Paul and yes I will be following his advice. Off to spend some pennies and get track now for the fourth track and hopefully have 4 locos running smooth and perfectly. But no rush - taking my time on this one! PS can you keep the rain over your side please? Our Norfolk bye roads can't take all this wet stuff!

So good to see the trains running around Steve and the further work in laying the third track. The triangle is going to be very useful, and I suspect you know this, but you will need an autoreverser to control it. It was quite difficult to see what was causing your short, especially as they look to be insulfrog points. From what I could see it is the Pannier loco that is causing the short and then the rear wheels of its last coach. A bit odd nothing in between causes problem. It was quite tricky to see but it looked to me at 15:03 that just below the rear wheels of the last coach behind the Pannier, there is a power feed (a red wire). If so that is at the wrong end of the point. Points must be wired at the toe end before the point blades so that the blades can direct the current. It is possible that something is bridging intermittently over the junction given that the Castle sailed over it Have you been able to run trains over that junction? Stephen
Thanks you Stephen - that power lead is an old one that I need to take off, but I think I have narrowed the issue down to dirt between the plastic guides and the rail which push's the wheels over, and after filing with a very thin jewellers file plus fine sand paper seems to help. However, I am gong to move the dropper wires as you suggest and see if that works. Failing all that, I do have a spere point I can swap in but that would mean a few hours of taking other track up etc. That would be my last resort. I have not heard of an auto reverse before so will be researching that now - thanks for the tip!

@@lynganddistrict Good luck in curing the short. With a reversing triangle (also often called a wye) the polarity has to be reversed at some point as the train passes through to prevent a short circuit. I think you use DCC Train Automation and I've looked on their website and they do sell them. I am sure he will be able to advise you because I think you will also have to fully isolate each part of the triangle (Isolating rail joiners will do the job) and there may be yet more to wiring the triangle than just the reverser. It will be really useful addition to your layout. I saw one in use on an N gauge exhibition layout built in a T shape at the Warley Exhibition a few years ago. Stephen
Hi Steve I bet it's lovely been able to run 3 trains and work on the layout. One thing if you do go on to itrains we're you have 3 trains running the train that fuses in that block or over two block's the other two tracks keep going and if you had two trains running on the track what fuses the train what isn't affected will keep running up to the block before the problem block, if that makes any sense. Hope you and your family are well. Colin
Yes Colin it was - a major step forward for me as well. Yes it does make sense what you explained, but I think I am still going to investigate how to have each of the four tracks on a separate isolated circuit so if one fails the others continue - before I have ago at ITrains that is.
Regards
Steve
@@lynganddistrict Good plan
@@lynganddistrict Just a thought (as I laid in bed) are you going to have more than one dcc controller, because it's the controller that fuses, if all the 3 circuits, are connected to three separate buses if there connected to one controller they will all stop or is there a electronic you can put in between the bus and the controller to fuse separately. If you do come up with a idea the points that are connected to take trains from one circuit to the other both rails will have to be insulated.
On my last layout I did put it into zone's off one controller but that was to make it easier to fault fine.
p s (then fell asleep so sending now) 🤣
@collinsngauge5493 I think there is an electronic block that has 4 relays one for each track that shuts off power to the track affected. This will mean each track would need it's own detection decoder. I have two so would mean purchasing another two plus the relay block but that's way down the line. I have managed to reduce the shorting to one in every 10th circuit of the Loco so will continue to clean the affected point until I am happy. Thank you for thinking about my issue tho ... very much appreciated.
Regards
Steve
@@lynganddistrict Those electronic sound interesting have a good weekend.
