Be very careful in using twisted wires for DCC as it can cause crosstalk in the DCC signal and result in strange things happening.   :worried:

That explains all the weirdness my computer finds on t'internet. :worried:

I think the received wisdom is the opposite of this.

https://ncedcc.zendesk.com/hc/en-us/articles/205474045-Twisted-Pair-Bus-Wiring

“twisted pair construction on long cables runs on large layouts.“

Unlikely to be a problem on smaller UK layouts ( and mine are as straight as they come!)

Cheers for all the feedback ... yup I'd done some research on this as there seemed to be some confusion! As a newbee I thought I'd better try and get it right!  :dunce:

As the NCE page says "tight spacing between the wires takes advantage of the physical properties of wire and environment which work to improve communication and control over long cable runs".

Spent some time putting in the bus line today!




On the left you can just see the NCE Power Cab tacked on to the end of the baseboard, at the mo it feeds the track directly using a Kato 20-041 62mm Single Feeder Track!




On this one the bus wires follow the track layout for Lavaux above - at the far end I'm hoping that ONE bus line can feed the double track!?




Here I am using TWO bus lines (or rather the continuation of the same one!) to feed the double track and the Station Yard that is above.

Next job is to attach the power to it and test it!! But as I can't face the disapointment of it NOT working   :worried:  ... I'll leave that for another day!

Cheers !!  :beers:

I am happy to report that the bus is running ... the track!!

I disconected the Kato 20-041 62mm Single Feeder Track from the Power Cab, and made a connection from the CAB's connector to the bus line, and moved the Kato Feeder Track to another (final?) position and connected it to the bus line also.

Then I put the power back on for the NCE Cab - and did the 'coin test'!  ??? Actually I used a drill bit which worked as the Cab shorted out as expected.

So then I put the locos back on the track, and they ran fine!   :claphappy:

Next job is to try the inclines I'm hoping (expecting  :worried: ) to have in order to get up on to Lavaux!

Cheers  :beers:

Have been setting out the 'Yard' at the station, and getting the feeder wiring in place. Thought I'd share what I was doing ...

The Yard comes of the main line using a 'Kato 20-202 Left Hand Electric Point Radius 718mm 15 Deg', followed by two K20-203 Right Hand points (r718mm 15deg) and a final K20-202 LH point. In between each point I want to put 'K20-041 62mm Single Feeder Track' (blue arrows), and to insulate the points on the 'Y' side.



To do this I had to remove the joiners that were on the 'Y' side of the points:



using thin nosed tweezers:



and just easing the joiners out of their position:



Then I just popped on the insulated joiners:



Now I can connect to the feeder track:



More soon! Cheers:  :beers:

yep, insert and twist. No need for fiddling around with tweezers.

I claim a UK record for the "insert and twist" method. I sent a unijoiner flying just short of two metres as it popped off the rail.  :claphappy:

Yes, me too.  From ntpntpntp as I recall.  Thanks again.

Well, Alec, I don't know.  One of my 'Unijoiners' is still missing.  And Poppy got one heck of a fright, although I'm glad to say that it did not hit her.  But I've got form with flying things.  :dunce:  I jointly claim the flying circlip record for a plunger frame Norton ES2.  My chum and I failed to appreciate the amount of spring loading on the plunger suspension units.  We were about 18 years old at the time and learning the hard way.

Best wishes.

Are you planning to run freelance or any particular prototype?

If you are doing main line you might consider opting for the Kato double track with superelevted curves. It's great for main line running.

Hi Gordon, thought about Kato double track but decided against for this (first ever) build, just to keep things simple for me.  :worried:

Cheers  :beers:

Small update just to show I'm making (slow) progress ...

The mainline track at the station and much of the yard has been wired in and tested, and then glued down:

[erm ... where has the 'add image to post' link gone!?
Ah HA! I have a new app thingy called Grammarly that was hiding the attach photo link!! Switched it off to add the photo ... and back on to check spellings!]
 


The two crossovers on the mainline are in and just out of shot is the point from the mainline to the yard, which along with three points for the yard are all wired in and powered at all ends. The loco shed is placed just to get an idea of where it might go. If you look closely at the two spurs (just in front of my soon to be patented track-glue-it-down-weight-system) you'll see that the ends of the buffer bases encroach onto the main line! So either I shorten the spurs, which I don't want to do ... or I 'modify' the rather long 'tail' on these "Kato 20-046 Ground Level Buffer Stops"! Not sure yet may have to test with a loco and some carriages to was clearance is needed.

Anyway ... I am getting on with it ... honest guv!

Cheers  :beers:

PS: note the digital multimeter in shot - that I've been brave enough to buy thanks to a rather good tutorial on how to use it!

OK ... it's about time I showed some progress on this! SO ... for the FIRST TIME ...

ALL the track and inclines are 'in place'.  :claphappy:



The station and yard are now bounded by the incline snaking it's way up to a tunnel above the main line tunnel. I'm hoping to put a road in along side the track that will drop down and turn around to the parking area at this end of the station.



The mainline tunnel (below) has the temporay roof that is a template for me to cut from the extra baseboard material I have. I'm hoping that this will be removable incase of problems - and the tunnel side will be open in any case to get to any derailments at the point there.



I used an extra long coach to test the clearance! As I'll not actually be running this ... then all others should be ok - right?  ???



This is where the small viaduct is going to go. It will have a small road through one middle arch, and a small stream through the other ...
I can picture all this in my head you know!  :idea:



The afternoon sun bathes the grape vines, while the track glides it's way through the stepped vineyards (corrected from the french 'vin yard')! Can you see it ... can you?



The tunnels through Grandvaux - while these shouldn't be a problem [:-\] as there is no turnout here; I'm wondering if I should make part of the tunnel removable ... just in case!  :'(



This last shot (below) is looking down on the yard from Grandvaux - which will be impossible later !!



Right SWMBO is home - tired and hungry - so I'd better go cook!

Cheers All  :beers:
