RMweb Premium Popular Post St Enodoc Posted September 12, 2021 Author RMweb Premium Popular Post Share Posted September 12, 2021 (edited) After our walk this morning, I picked up the resistors and capacitors from our local electronics shop and after lunch made up and fitted the two RC filters. That was at about 1300 and between then and 1700... . . . . . ... the system behaved perfectly, with no freezes. That could be coincidence but for now I'll take it as a win. During that time I finished the sequence (as before, without the railbus services). There are a few minor things to put right on the spreadsheets but overall it was a successful session. To round it off I took just a couple more photos. Train 584 is the Up Royal Duchy, which on summer Saturdays is strengthened from its normal 7 coaches (4 on the model) to 12 (7 on the model). It left Penzance at 1150 and we see it here just after passing Porthmellyn Road, on time, at 1330. D816 worked down earlier on the 0035 SO sleepers. I rather like this viewpoint for Up trains and I think I'll make more use of it. Because the Pentowan branch is (or will be...) so busy with holiday expresses on summer Saturdays, there are no paths for Wheal Veronica china-clay trains and only two for St Dennis Junction, one in the early morning and the other in the evening. Here is the latter, 4247 on the 2040 St Dennis Junction to Tregissey (train 646), about to pass St Enodoc station.

RMweb Premium acg5324 Posted September 13, 2021 RMweb Premium Share Posted September 13, 2021 Back in the mists of time……well about a year ago…….we were in Cornwall and I mentioned we had passed a sign for the St Enodoc hotel. I think John you asked me to get a photo of it next time we were near there. Was it just the road sign or the hotel? We will be back in Cornwall end of October. 2 Link to post Share on other sites More sharing options...

We are staying at Hawkes Point again, different apartment. Got various restaurants booked for the week including lunch in Portleven at http://www.kotakai.co.uk on our first day……we are stopping overnight at Gloucester on the way down. It’s bad enough doing Carbis Bay to York in one go on the way home. 2 2 Link to post Share on other sites More sharing options...

After I switched everything off for about 15 minutes all was well but I really need to find out somehow what's going wrong. This happens to me and my thinking is that the DDC system simply gets confused by a very large number of instructions over a longish period, particularly if you input many commands in quick succession. Its as though its memory has a finite capacity (which being a computer it must have) and either that gets filled up or data inputs to it get misread. I always find that simply switching it off and restarting it after a few minutes clears the problem - exactly like a memory leak on a PC. My only suggestion to overcome this is to always input instructions in a more measured manner and don't ever rush things. Don't input a command, realise its wrong and hit a rescind or cancel button repeatedly. In short treat the system gently and with respect. 3 1 1 Link to post Share on other sites More sharing options...

Having researched this with some of the gurus, I'm now convinced that the problem is something to do with signal degradation, or noise, on the cab bus, which in my case is long and has several branches/spurs. This may well be caused, in turn, by the length and geometry of the track and accessory buses. The best mitigation (not cure) is: - an RC filter at the end of each zone on the track and accessory buses, furthest from the booster. I use a 10ohm 5W wire-wound resistor in series with a 0.1microfarad 50Vdc ceramic capacitor; and - keeping the cab bus as straight and as far away from the track and accessory buses as is practicable.

Agree about keeping the cab bus away from track and accessory bus. Less sure about ‘straight’, but would add cross at right angles. Not being NCE but extrapolating from Loconet, I assume that the cab bus has to go to all controllers and mini panels. As a possible test methodology, could you reroute the cab bus aerially so that it is nowhere near anything dirty. Think cab bus = signalling, track bus = traction. There is a reason why we want to keep away from your nasty dirty electrons! :-) Paul. 2 1 2 Link to post Share on other sites More sharing options...
