  1. A few more views of 37049 at Crianlarich on the down sleeper. Intriguingly Cab Control started track power twice yesterday at the first time of asking leaving me wondering if the PSX are having a positive effect. I doubt that the Tam Valley soft start module I have bought will be here before the middle of next week meaning I have several further start ups to test the theory.
  2. I spoke with Kevin at Coastal DCC this morning who advised that to the best of his knowledge the ALR in the PSX was to all intent and purposes a soft start. There is nothing in the PSX instructions to explain ALR so I have e-mailed DCC Specialities in the US to see if they can provide greater clarity. Having read the supporting literature about the Tam Valley start up module and for the modest £17.50 it cost, I have bought one to see if this solves my issue. I now have three potential solutions namely: Tam Valley start up module, simple wiring change to install between ESU ICU/booster
  3. 20045 shunts an S&T engineers train out of the sidings and onto the headshunt at Crianlarich where it waits for 37049 to arrive with the down sleeper. After 37049 departs 20045 exits the headshunt and heads for the Oban line.
  4. I was out for much of yesterday so little done and no response from ESU so far. On this and another thread I have received lots of constructive counsel about the issue of power surges on start up. It does seem to be a more common occurence than I had first appreciated and not just with ESU equipment; it would be great to find a solution to cover most if not all eventualities. I have bought 2 more DPST switches with a view to further dividing up the power BUS into more sub-districts to see if this works. It will be a bit of a pain installing them because it is the main fiddle yard that needs to
  5. check Ebay, this should answer most of your questions https://www.ebay.co.uk/itm/1982-Working-Railway-Timetable-Western-Region-Section-PC-Exeter-Barnstaple/353260768328?hash=item523ffb8c48:g:1IUAAOSwLq1foHEO
  6. Hi Keith The CC manual is silent on any short circuit parameters, it is generally pretty lightweight on technical stuff fullstop. I posted the question asking what are CC short circuit parameters on Facebook 2 days ago; no responses as yet. I sent the same question to ESU Technical Support at the same time; again no response as yet. Same on the ESU forum as you have seen. I do'nt expect to be given a way to vary CC short circuit settings by ESU, however detailing what the short circuit parameters are does not seem an unreasonable request of them. If the parameters are known then d
  7. Thanks to everyone for their contributions. I have e-mailed ESU technical support highlighting my problem and asked them to advise what the trigger settings are for the short protection and if they are user changeable. If I can get this information then I can judge what to do next. My issue is very similar to a number of similar ones on the ESU forum so it is clearly a recurring one. Whether ESU are able or minded to do anything is, of course, another matter. I will also see what more I can find regarding PSX's adaptive load reset functionality and if it is customisable. If anyone
  8. I have asked ESU technical support for information relating to the short circuit protection in Cab Control. ESU have not responded as yet so for now I will leave matters as they are with the PSX's in situ for a few days in the hope that ESU respond. The layout is perfectly usable once CC decides to allow track power to be started. The first southbound train of the day in 1981 was the 0700 Mallaig to Glasgow seen at Mallaig with 37081. It has been my intention to crack on with finishing the scenery on the Mallaig section as my next project but I have become distracted by the electri
  9. Hi Ian The ESU forum is useful but there are more questions on it than answers! I have a thread running regarding this and I have e-mailed technical support at ESU because there are several outstanding questions along similar lines. As others have suggested, I am sure the underlying issue I am facing is a very sensitive setting on the Cab Control short circuit protection. What is measured, how to overcome it and if/how the setting might be adjusted are the sort of information I am after from ESU. I am not persuaded that a booster is the solution to my problem because on
  10. Another day of challenges with electrics saw the removal of the DPST switch and the creation of 2 sub power districts protected by the installation of 2 PSX circuit breakers. Re-reading the last sentence makes it sound like I have an understanding of electrical stuff which is a gross misrepresentation of reality. I am totally out of my depth and reliant on the goodwill of others to help me try and find a solution. All of the detective work so far arrives at the conclusion that the intermittent power start problem is caused by Cab Control's short circuit protection which interprets the high pow
  11. Thanks but no to any loco stay alives. I have 2 coaches with lights and stay alives but these live in an electrically isolated siding so have no effect on start up. They dont get illuminated until I set the route for them to exit their designated siding. I need to understand what it is that Cab Control measures to determine a short, if I can find this out I have a chance of finding a way around the issue.
  12. Absent knowing how long capacitors hold their charge after power is disconnected I decided to switch everything off for 30 minutes and then re-start. Annoyingly it was back to normal, track power took a dozen or more button pushes before connecting. So much for the PSX's adaptive load reset capability! I have Railcom enabled on my controller which I have read can cause issues with PSX. As a further experiment I will turn this off and see if this any effect of the situation.
  13. I have further tested the PSX's and found that on creating a short by approaching an incorrectly set point, it is the PSX which cuts track power and not the controller. That is a relief, I was uncertain which of the two was set more sensitively. By changing the point to clear the short the auto re-start of the PSX restored power. At least something seems to work as I want!
  14. I appreciate peoples input. I think it is clear that the sensitivity of the ESU Cab Control short circuit system is tuned considerably finer than my previous Guagemaster Prodigy which happily ran the same layout without fuss or similar issues. In between posts I have been wiring in two PSX 1 circuit breakers running software revision L to create two new sub districts. I appear to have followed the installation instructions correctly because on powering up the layout I was able to apply track power on the second attempt. I then switched everything off, waited 10 seconds and powered
  15. I have already tried this, admittedly only 1 DPST switch which created sections that held less locos. The split was about 10 in one section and 15 in the other. The switch made no difference, I suspect that my main fiddle yard is the cause because this is where there are typically as many as 15 locos at any time. The fiddle yard could be divided into sub districts but that would involve a lot of re-routing of wiring which I dont fancy doing if at all possible. If the PSX does what it says then I hope it will resolve the problem. What is really frustrating is the intermittency, som
  16. My poor comment, there are 25 locos on the layout but rarely more than 6 actually running their sound function at any time. All locos have sound switched off before I shut down power at the end of a running session. If I inderstand correctly (which is by no means certain) there is an intial in rush of power when first switching on caused by the chips charging their capacitors? This ocurs irrespective of whether the sound is on or off and it is this spike that causes CC to trip. I'd guess the power demand would be higher if the sound was on but that is not the case here. What I am
  17. It must be down to my clean living life style! Alternatively it could be that I did not mention the 10 minutes of irritation and frustration that it took to connect track power before I could run trains. Fortunately from several years of trouble free operations I know that my wiring is robust and that my issues relate solely to the controller. If I had not had this experience to reassure me, I dread to think what I would be like with the short circuit problem.
  18. a lot shorter than the siding! The Grampus rake of load 8 which was in the siding was split in two to enable it to be extracted. Picture shows the two halves about to be coupled back together. The train then sets back to the signal before taking the usual route through the station as it headed north.
  19. I am having difficulties with applying track power using my ESU Mobile Control which is part of their Cab Control (CC) system. It appears that the initial power draw/rush of my 25 locos all fitted with Loksound chips (V3.5 x 5, V4 x 15, V5 x 5) causes CC to intermittently trip its short circuit protection. I have adjusted the CC current limit setting to the maximum of 5 Amps and CC clearly provides adequate power for my locos once I get past the initial start up issue because I am able to run trains without any problem. There is a live thread relating to CC where I have received considerable a
  20. Railmatch RM2304 warning panel yellow covers 60's to mid 80's. Railmatch also do a faded yellow RM452 in enamel. I have a 30 year old bottle of this which is still in fine working order!
  21. PSX claim that their circuit breaker has adaptive load reset which will address the spike in power on start up. I have managed to get my hands on two scrounged temporarily from a friend meaning its more time to be spent on wires again today! Having become thoroughly hacked off with the electrical challenges and learning opportunities, I gave up and ran some trains instead. 37017 shuffles loaded Grampus out of the siding at Crianlarich.

  23. The driving force is to stop the spurious shorts Cab Control senses on applying track power which probably arises because the short circuit protection treats the start up power surge as a short and cuts out. I understand that your description of typical power districts is the normal reason for their creation and would have installed circuit breakers to my 2 districts but at £40 a time for PSX solid state ones I considered that the cost benefit did not stack up. I am still not certain that a booster is the solution, if it is then I will buy an ESU one so that I have all products fo
  24. Mmm, several hours later and the DPST switch is installed. Electrically there are now two distinct sections with power on/off capability on one of them. On first start up of track power the Cab Control spurious short was still evident, subsequently it was not. I fear the power separation into 2 districts is not the solution I hoped for. I have no idea what to do next, some head scratching is required. Pictures show the DPST switch with both + and - wires cut as described by ISW.
  25. Work on the power BUS to make ready for the 2 power districts continues. Below is a schematic attempting to show what I am doing, from having a horseshoe shaped power BUS the BUS will be cut in half at approximately its midpoint. The half (or district) that powers the fiddle yard section around to Ardlui shown as Section A in pink will be connected directly to the power supply from Cab Control. The second half (district) controlling Garelochead around to Fort William shown as Section B in orange will have a DPST switch installed between the CC power supply and the BUS. The on/off s
