    With a separate accessory bus, you don’t use the ‘frog’ output from the cobalt.  You wire the track bus to one of the switches and the common from that to the frog.


    Fortunately, I was already aware due to some excellent posts on this forum.
    As I understand it, the advantage of the accessory bus is that when I short the track bus due to not setting a point correctly, I can still drive the point motor via the accessory bus.

    I haven't actually got as far as installing a point motor yet, but my plan is to do one and get it working all the way from JMRI's panel with control via WiThrottle before I do the second one.

    If everything is wired to a common bus it’s much more difficult to sort later when the annoyance gets you.  My suggestion would be to wire back to the control box separately even if they common up in there.  So much easier to sort if (when?!) you decide you need to.


    Fantastic point Paul! I'll pick up two different colours and run a separate bus for the IP digital points.

    I've never tried this for real, but....why not have a the bus as a complete loop around the layout


    I've not done enough research, but I'm pretty sure that I've read that you shouldn't loop a DCC bus. at 2m long in each direction of the "L", I'm not worrying too much about it all as it's a relatively small layout. I'm not totally sure if I'll bother with an accessory bus yet!

  4. Second board wired up now!

    I've essentially run the bus along the side where the most droppers are closest, hence towards the back on the left board and the front on the right hand one.

    Obviously, with both station boards done, I had to test it out!

     

     

     

    It works!

    I need to lay complete the track on the third and fourth boards and wire them up next. Then on to the point motors.

    Might just turn a few locos up and down first though…

  5. I visited yesterday and was incredibly impressed by the presentation of Shwt. In addition to being well lit, it is also quite a deep layout, with plenty of space front to back which really gives a sense of the place. Makes me wish I had an extra foot of depth for Holcombe!

    It was also quite popular!

    SHWT was popular at the Bristol Exhibtion

     

     

    Many many thanks to @Johndc120 too for explaining how Shwt uses WiThrottle and JMRI to allow routes to be set from the phone. I very much appreciated being able to look behind the scenes and have a walkthrough of the JMRI set up, particularly as I imagine exhibiting is already a busy time. It was enlightening and I'm looking forward to doing similar on Holcombe when I get to that stage. Thanks!

  6. I visited yesterday and it was fantastic to see Templecombe Lower! Very very nicely done. I took a few photos the with phone as I enjoyed watching the start of the daily sequence:

    I always have a soft spot for a 2P

    Ivatt 2MT and another 2P!

    The pilot is used on all trains from Templecombe Upper back to down to the junction. There was a lot of operational complexity at Templecombe and it's captured nicely here.

     

    I also very much appreciated the slides telling us what was happening. Very engaging for those of us watching.

  7. The DCC solution I chose is DCC-EX.

    I didn't want to build it all from scratch, so purchased a complete system from Chesterfield Models. This included a box with a Motor Shield and an Arduino running DCC-EX to connect to the track along with a separate box containing a Raspberry Pi running JMRI as set up by Steve Todd

    With the power supplier as well, I decided to put it all in a wooden box to keep it all safe and together.

     

    The iPhone is an old one that I had lying around. It runs WiThrottle. The system creates its own WiFi network so the phone automatically connects and is ready to as soon as I turn it on which is nice. I run JMRI by VNC from my computer to the Pi.

    It all works nicely and even provides a separate programming track output in addition to the main track.

    Quite pleased with the holes that I drilled. Turns out that using a rule and pencil first helps!

  8. I intended to do some wiring today, but I don't have the right bits, so I have ordered them.

     

    Instead, I decided to cross the next baseboard join.

     

    There's only two for this one. Firstly the pretty straight line to the industry:

    Another join crossed

     

    and then the curve… I bought some templates from WHWW and used the 638mm one:

    Ensuring a consistent curve

     

    and of course am now waiting for the glue to dry!

    Weighting down the track

  9. After this weekend's work, the track in the station is laid:

    Track into station is laid

     

    All droppers in position too, but no point motors yet:

    Lots of droppers to wire up!

     

    I think that I need to sort out the DCC buses (track and accessory) next which will require working out a solution for joining the wiring across the board given that I can't get at the underside until one board has been disconnected.

    What about this as a solution from Modeltech, haven't used it myself but looks like a good bit of kit for aligning track over baseboard joins.

     

    I looked at those, but couldn't work out how to use them with angled and curved track. 

    All 4 done now though!

    All 4 baseboard crossings done
