    That is excellent Gormo. :thumbs::thumbs::thumbs:

    So does that mean no words are spoken in the train room ?? ;) Do you have one to the kitchen for when you want coffee...?? :scratchchin::avatar::avatar:

    Cheers, Gary.

    Now that you've found and fixed the fault, are you going to post an updated diagram,
    for us mere mortals!

    Thanks Gary,
    Well you could do it without speaking but it would have to be done also with a train schedule or timetable in place.
    If I put one in the kitchen, I would have to start sleeping with one eye open for fear of being suffocated in my sleep............:avatar::avatar:

    Well an updated diagram would mean a circuit diagram and that`s a lot of work......I`ll think about it.......:scratchchin:

    G`day Folks,
    Well I got some cable yesterday and wired up the last two 25 pin plugs that connect Little Bardfield to Bamford. The power feeds were also completed and all cables were installed and cleaned up this morning with cable ties etc.
    So the major work on the Block Instruments is complete. They are all tested, connected and fully functional. I have left myself a spare foot or so of cable too long on the run between Little Bardfield and Bamford in case I have to move the Bamford instrument a small distance from where it`s sitting at the moment.
    My next task, which will be a picnic compared to the build , will be to do the track feeds. That process is partially complete from previous work done, however I need to go in and finish the job.
    I hope to get a good deal of that completed today, but we`ll see how the day pans out as I have other chores to do as well.
    This is the cable coming into the backs of the Little Bardfield instruments.......doesn`t look that bad now, but there are twenty wires to each instrument plus the power feed and each instrument still requires an additional four wires from track feeds.

    Actually you could run trains through the system now, as it is independent of the track. It`s a bit like traffic lights. Even if they are Red, you could still drive the car through them along the road.
    Not a very safe way to drive....but possible, whereas once the instruments are connected to the track, if they are showing line blocked, a train will come to a dead stop once it hits the isolated block section.
    The operators have the responsibility of operating the sections safely and each operator will know what the other is doing via the Block Instruments.
    It may generate some lively banter in the room......especially if we start running to a timetable......actually I think scheduling is easier than timetables, but that`s a whole other topic.

    Well, to keep the grey cells active Gormo. I think your next step is timetables- bleed'n good fun there creating them... i am into version 8 of the current batch ( I have still about 12 or thereabouts of earlier than those 8 )

    I’ve got a time table for my Oakamoor layout. One train in section and runs as required. ! :facepalm:
    Till my lad comes along.... then it’s class 58 on a GWR auto coach in to the old platform

    Yes, you`re probably right there Sol, however I think I need a mental break for the moment.......this project has tested me and I`m looking for something different and relaxing for a while.........probably I`ll go back to scenery.?...Little Bardfield has been on hold whilst I`ve been working on these instruments.
    I also need to look over a few of the bell code lists from various railway companies and pic the eyes out of them so as to create a fairly basic, easy to use list of bell codes for GCJ.
    Of course the reason I`m now looking at bell codes is because the block instruments are fully installed and operational and testing has been completed.
    This project has been on my to do list for about seven years now, and has always been waiting , I guess, for the right time to actually dive in and have a go at it.
    Much testing was done quite a few years ago but was not really successful. I was trying to build instruments with needle indicators but it was not really working very well and also I was looking at a different way of operating the bells.
    Somehow, and for some inexplicable reason, I came up with the system we have documented in these pages......sometimes these things gradually morph into a semblance of an idea and it`s like unlocking the answer to a puzzle. Once you crack the hard part, the rest will fall into place behind it in some sort of logical fashion.
    Anyway......we`re all done.......Yyyaaaaayyyy !!!!!!.......:tophat::cheers::cheers::D:lol::thumbup:......:faint:
    :thumbs:Gormo.......stay tuned for a video coming soon

    Dear Gormo,

    re Bell Codes,

    1 / www.signalbox.org/block-system/bell-signals-in-use-in-1960/

    BR-WR Block Signal Codes with addendums for SR and LMR.

    These codes , in the main, date back to the RCH Model Rule Book of 1898. The large variety of bell codes is driven by train types and differing braking systems, including a lack thereof !

    2 / The Australian Model Rule Book of 1905 is a simplified version of the 1898 RCH version, and was adopted by all State Railways as the basis for their Rule Book Bell Codes.

    3 / I can supply you with the VR 1966 Rule Book Bell Codes if desired. ( This is very similar to the 1919 version, which I can also supply ! ) ( PM me with your post address if you require a photocopy please. )

    I hope this is of assistance to you,

    Regards, Echidna

    G`day Echidna,
    Yes the link to the signal box site was very helpful.
    I will send you a PM with personal details

    Hi Gormo,

    Came across this YouTube which covers UK bell code signaling. As far as I can tell it is exactly how you have done it except it has both DOWN and UP line indicators. I don't know if you have seen it? If not, I thought you might find it interesting.
