Thank you Robin for the reference. I ended up purchasing direct from Hobby Components https://hobbycomponents.com/other/581-4 ... -pins-male
rather than through Amazon along with some small Printed Circuit Boards they do, more of which anon.
I opted for a different approach to using them as I prefer to use multi strand cable and in particular Ribbon Cable to a tag strip one end and a small piece of Vero strip board to make a header for the connector end.
Although I have not posted for a while, there has been much progress, mostly with wiring.
I have progressed onto a second Storage yard board and fitted the headers to the Cobalt motors on this one.
Sorry about the wood dust, a result of drilling holes for the wiring.
I subsequently retro fitted those on the first board as well, which was a bit of a job with them already installed.
I had considered some temporary wiring just to get some track live, but decided against it.
Temporary things have a habit of becoming long term or permanent. I therefore decided to do the job properly as the less I have to revisit things later, the better. Those of a nervous disposition when it comes to wiring may wish to look away temporarily.
The small PCB under the center of the baseboard is one of Hobby Components prototyping boards and I chose to use these rather than Vero strip for my relay cards. For those of you into such things, they are available in a variety of colours at very reasonable prices.
These control the power feed to the point motors and are custom wired for each storage yard board. There is a standard PCB layout, but the number of relays varies to suit the required number of point motors for that board. These PCBs are designed to hold 4 x 16 pin ICs, so I have had to modify them substantially to accommodate 8, or in this case 7.
Mention of standards, the wiring for this bears a close resemblance to Green Street, my previous layout, although I have tried to simplify things a bit, it doesn't really show. Much of the documentation for this project has been derived from that for Green Street, and this has taken quite a lot of time to produce.
Indeed lately I seem to be spending as much time on the planning and documentation as on the actual wiring. However this side of any layout is important as it can save much time and effort later on and is often in my view sadly neglected.
The wiring of any layout needs to be able to cater for the operational requirements and thus pre-planning is essential. Although I am starting with the storage sidings, it became apparent that the entry and exit wiring would depend on the scenic sections next to them. This then led to planning the scenic track wiring, which led in turn to the signalling diagram and associated pointwork.
Christmas preparations have also taken some time this month.
