I've had to make a small adjustment to the trackplan by re-routing the line to Barton Tracey from the Fiddle Yard track to the Quayside one (in effect thus making the latter a siding off of the B.Tracey line) due to it getting a bit crammed in at that area.   This also meant another alteration to the wiring plan - in fact more than one, for various reasons :roll: :oops: - which Trevor once again took a lot of time and trouble with and for which I am inestimably grateful - and that's putting it mildly!!!   (See 3 below).

 
In the meantime I started trying to create a trackplan for the switchboard (based on one Trevor had done for me much earlier) and after much trial and error I managed to produce the following using an editing programme which I'd hardly ever used, and have to say I'm very pleased with the result:-




Trevor then based his new wiring schematic (mentioned in the first paragraph above) based on my trackplan as follows:-




My next step was to make the actual switchboard and utilising some plywood and a plasticfilm stationery folder - the latter to keep the paper printed diagram from getting marked etc - I produced the following:-



Below is the back of the board and you'll see the crude "squares" I had to cut out to accomodate the switches due to the ply plus the folder being too thick for the thread length!:-




You will see there is a blank one numbered 16 and that's there in case I decide to add another track from the small branch station to go behind the Quayside Warehouse to places new!!!   This switchboard will hinge to the front of the baseboard and will pivot allowing me to get to the back for wiring or problems etc.   

I'm now ready to start laying and wiring the track and have been trying my hand at soldering etc before starting on the real thing; so far I've made a bit of a dog's breakfast at it but hopefully I shall get better as I go along. :sad:

More in due course, Ken.

Just a point for the casual observer trying to follow this and the beginners electrics thread.

The wiring diagram shows the wiring for what is called Common Rail and a common black wire goes to the different points.

Ken has a Gaugemaster dual throttle (do not ask me the model number) which is OK for common rail otherwise you would have to ensure that you have two separate transformers for the controllers. Something along the lines of a Triang P5 and an auxiliary controller will not... well it will in one direction or the other if the locos are on but not trying to work them in opposite directions.

I think Ken has spared you of the work behind the scenes to get this far and I'm looking forward to seeing more of his efforts... hope the rest of you are too!

Trevor

Very neat and tidy control panel Ken.
Have you started attaching the wires yet?

Any chance of an overall layout area photo to help us get this build in context. Doesn't matter if it's all bare boards or not even that yet. Gotta have somewhere to start.

cheers
Marty

Yes Marty, I've completed the first part of the Control Board wiring - the 2nd stage will be from the track to the switches - and I actually found the soldering relatively easy I'm pleased to say (in point of fact I was quietly dreading it!). :oops:




Below is a picture of the baseboard (taken before the recent slight track modification) and which I did post in my initial "Help wanted..........Wiring" posting

 

It doesn't look in such a pristine state now as it's covered with all sorts of plans, odd track pieces, bits of wood, packets of this 'n that etc!!!   Anyway, it's all got to come off now as I'm starting on the track laying so more on that in due course.

Ken.

That's an economical way of wiring them up Ken, I hadn't thought of doing them that way. Always something new to learn.
I'm glad you've come to terms with soldering, you'll find it opens up a whole new world of modeling possibilities and it quite fun.
I've even used it around the house to mend things!

Thanks for the reminder of the layout space you have, puts it all in perspective.

I might suggest for your consideration, before you lay track, that I found that I should have painted the base sky blue on the back scene prior to putting toys on the board. This avoids the toys having lovely sky blue spots!! Just a thought.
Marty

I can't believe seven months have gone by since I last posted, however there is a reason:  I had a bit of a layoff from modelling during our so called summer as I've done quite a bit of cycling (on my super new bike) and started playing Tennis again - at the age of 77 - after a 12 year break due to bad back, knee and neck injuries caused by same!    I'd missed playing so much and thought I'd give it a whirl and although my old problems surfaced at first I'm now playing quite well with few side effects so I'm really loving it.

Anyway, to get back to the layout I've included a new drawing and you'll see I've added 2 extra sidings as I wanted to accomodate my quarry (which I had worked on when I first joined YMR) and the crumpled binbags represent the hills around same, of course I'll be doing this properly asap but wanted to see how it looked first.   I've also added a new track section behind the Quayside Warehouse to enable me to extend the layout by another 8 feet or so at a later date - assuming I ever complete the main part first!   There are some other changes too: I've done away with the sector plate as operating it would be too complex as it's hidden under the fiddle yard so I've changed this to dead end switched sections, plus some other track positions have been altered slightly at the main station and an extra siding added in front of the harbour.  

All the track has now been laid and ballasted - a horrible job particularly in N as it's so small it floats around when adding the PVA/Water/Washing up liquid mix - and all droppers have been wired, tested and now have to be connected to the bus wire and switches, then all to the controller.   This will be my next job but first I have to connect the point controls for which I have come up with a newish system and which I will elaborate on when completed.

Incidentally, the hidden fiddle yard will have a village street with houses etc on top of the removeable lid, and I spent a bit of time experimenting on how to do this without minimising the station platform too much, and how the passengers would access same.   I based this on Bampton (Devon) where a ramp slopes down from the adjacent road bridge and all will become clear in due course.

Again I must acknowledge Trevor Gibbs' help with all the electrics, he deserves a medal for the amount of time and trouble he has taken and my gratitude knows no bounds.   Anyway, here's a few pictures:-















The only thing that concerns me now is: have I put in too much track at the expense of scenery particularly bearing in mind that the scenic aspect is what I like doing best!   However, I think there's still quite a lot of scope for this particularly with the interesting buildings I plan to scratchbuild (the quarry one is based on John Ahern's and I've always wanted to do this) and the harbour area in particular should turn out to be very interesting. 

Ken.

Hi Ken

A great looking layout. It is amazing how much you can get into a reasonably small space with N gauge track. Having just built, and dismantled, an N Gauge layout myself (see Watton Erith) I am always interested in operating branchline terminus layouts in this scale, as there is quite a bit of coupling and uncoupling as trains come in and depart. This is not easily done in N gauge without a fair bit of messing around. I would be very interested in your plans, especially for passenger trains in Combe Hinton station and shunting in the sidings. I spent ages deciding what to do, but ended up using the Dapol magnetic uncouplers on my layout and then ran the locos around a loop to head the departing trains out of my station.

Bob

It's looking very good Ken - I like a man who goes to the trouble of sealing the screw holes ...........;-)

Which half day did you go cycling this summer ?  I didn't think UK had had one this time around ..........:shock:

I'm sure you could get away with platform access down some steps from the upper level.  I see a long stepped ramp with a "landing" for a breather half way down.  Some nice wrought iron guard railings would give it some class.

I too am looking forward to seeing what you opt for in terms of coulping/uncoupling.  In "N" gauge, that won't be easy I'd imagine.

Some lovely sweeping curves there with a complex looking central junction - all just up my street. :thumbs

Looking forward to seeing the scenery development Ken.
A very good trackplan....busy without looking overcrowded.....:thumbs

Wow, it may be a while since the last post but you've made some decent progress in the mean time Ken.
I think you have struck a good balance between track and board, looking at the station building and the mine in place in comparison to the entire layout.
Nice ballasting too.

Cheers
Marty

Superb work so far Ken!Looking forward to seeing the scenics come in too,its all looking very promising.I'm particularly interested in how you'll tackle the dock area.

Cheers,John.B.:thumbs

Thanks everyone, and to answer your questions:-

Novice and Petermac:   Re uncoupling I thought I would just use Peco uncoupling ramps (or ones I will make myself) placed in various positions (ie dead end sections etc) and rely on 'forced' coupling (i.e., back them against each other) ;-)  but have already found this is not easy due to their light weight.   I'll come up with something though when I can give it a bit more thought, however, any suggestions on both aspects will be much appreciated.

Peter:  Your idea for the smaller station access is exactly what I had already planned (I'd made the stepped ramp and tried it in position when I experimented with the fiddle yard top just to make sure it would all fit ok).

JohnB:  I actually have the Dock area all planned out but don't want to elaborate on it yet as there are so many other things to do first, however I can promise you it should be very interesting if I can come up with the modelling to match my ideas! :roll:

In the meantime I've had a problem!   Peter mentioned lovely sweeping curves but I found that one of them didn't fit that category (I'd already thought it could be an issue and sure enough the join angle was far to acute for a loco to run on).   However I found a simple solution - and don't know why I didn't think of it in the first place :oops: - by swapping over the original head shunt as per the before and after pictures shown below.   A fiddly and messy job as I had to remove these ballasted sections and cut the new track very accurately to 'spring' it into position between the existing tracks;  luckily it didn't necessitate the wiring being altered in any way.   You'll see on the plan the zig-zagged marked track which has been removed and the new tracks which are shown in blue:-







Incidentally Novice, Watton Erith I well remember and was an inspiration too.

Ken.

Phew!!! One less Wiring diagram modification needed!!!  Seriously Ken Well done that it was adaptable enough to be changed. Good on you mate!

I hadn't spotted that errant join Ken - it was a bit "tight" ...........:shock::shock:

I think you'll find the new plan works much better and offers an extra degree of flexibility of movements not offered by the original "kinky plan" ........:thumbs

A brief update.   Because I altered the position of some tracks and added some extra sidings I have add to re-do my control board.   It was a bit complicated as the Fiddle Yard switches in particular had to be added to an area where there was very little room at the back of the board due to the reinforcing bar's 30mm depth (it runs along the top and supports the hinges).   I also had to remove all the wired in switches then re-align the new printed plan by matching up the existing holes plus adding the new ones then chiselling out the recesses to accomodate same - phew!    I now have to connect up the wiring for the five new switches and then all of the sections to the controller, anyway here's a before and after picture of the front and one of the back:-

BEFORE:-




AFTER:-





Incidentally the thin white line at the right hand side of the new plan has no significance as it happened in the printing! :cry:

Ken.

It looks very neat Ken.  You wouldn't know there was a problem top right at all.

Can you explain the wiring to an idiot please. :oops:  Everything seems to be connected to everything else.  Are these section switches or point switches or both ?

Peter, have a look at the original wiring plan below: it has altered since then due to the additional sidings etc but I think you'll get the drift ok.   (I haven't done a new plan for same as it's very time consuming and it's all in my head anyway!). :roll:

Basically they are all section switches except for the four on the left which are dead ends.   Have a look at the back of my control board and you will see I still have to connect all the wires from each section to the controller (the pink to each of the centre switch connector terminals and the black ones to the bus wire plus the track wires from the 4 dead ends shown in yellow).  

Your comment "Everything seems to be connected to everything else." is correct and you will see the blue and yellow wires to the switches are all in place.   As a matter of interest I did these first of all as it was my first attempt at soldering and I wanted to see if I could do it in the tiny spaces between each switch terminal (about 5mm) without soldering everything together!!!   As I said above, I still have to connect all the other wires to the centre terminals so that'll be fun! ;-)



Ken.

The fog is slowly clearing Ken .................:???::???:

i didn't fully understand what was doing what and, as soon as there are more than 2 contacts on a swich, I think "electronics" and my brain shuts down instantly !!

Trevor has also very kindly PM'd me asking what I didn't understand but I think he might also be shocked at my lack of ability to grasp even the simplest of circuits.

To be honest, I hadn't appreciated they were section switches (probably because I hadn't read what you'd actually posted and just jumped to my own conclusions ...........:oops::oops:)

Given a few more years, I'll get there .......................:cheers:cheers

Peter, by the time you have finished wiring your layout, you will understand it ( but by then, another new technology will be around to keep you busy).

Ken has learnt the hard way over some time - trail & error after guidance and he is showing good results :thumbs-
me,  I was lucky as that was my career:  DC/AC , switches & relays.
