  1. Hi, Just thought I would share my involvement in what at the time was a new venture for Irish Rail and ts commuter/suburban rail services following the success of the Dart service. It was planned to launch a commuter service linking initially Dublin with Kildare and later onwards to Portlaoise which would alleviate the pressure on the existing mainline routes south from Dublin and making use of dedicated new double tracking along the existing track way. I worked as a coachbuilder in Irish Rail and its original parent company of CIE from 1967 firstly as an a
  2. Thank you, I quoted a 3v transformer as the leds were advertised as only to be used with 3v, I have test wired three leds to a mobile phone charger and those are working with no resistors added and no blow outs so far. Really no idea what voltage that mobile charger is rated as it's quite old and the details are blurred on the casing. I will plough on so and order that speaker cable and see how that goes.
  3. Thanks again, I think I have the grasp of the different wiring methods and will most likely opt to use a bus wire, any thoughts on the strength of cable to use as the bus wire, I hope to source some from Screwfix but the choice is bewildering (to me at least!). I copped some reasonably priced drums of 2 core speaker cable and was hoping that might do the job, the wires coming from the leds themselves seem very fine so presumably a stronger cable is required for the bus wire, any minimum sizes I should be looking at?
  4. Apologies for the delay but I have been busy building a timber shed from scratch for my son nd it took rather longer than anticipated so no railway work done for a while, Can anyone please explain the difference between wiring the leds in parallel as against wiring them in series,and what exactly each term means for a complete electrics dunce like me. Also can I use the likes of speaker cable to run a bus wire round the layout for the leds, I have used a bus wire for point motor wiring, a lot stronger than speaker cable let me add, so I at least have some knowledge th
  5. Again many thanks to all respondents, lots of clear advice in those and previous replies, I can feel my confidence growing already, time to get ordering in those resistors and search the house, or more likely the kids houses, for suitable transformers.
  6. Many thanks to all respondents, looks like I need to swot up a bit more than expected, my knowledge and grasp of electrics is really poor and unfortunately much of the terminology leaves me blank, sad thing is that the likes of Maplins going out of business cuts out a reliable source of direct conversation with knowledgeable staff and a ready made source of supplies. As I am not UK resident and ordering of parts will have to b done by phone/email would the likes of Eileen's Emporium be a good alternative from which to glean one on one info and advice as well supplying whatever is n
  7. Hi, Just took possession of lots of single leds plus street lamps and platform lamps to try and illuminate areas of my layout, for which i believe I can use nothing higher than 3 volt transformer/s. Question is which type of transformer and how many do I need? Is there a ratio or limit to how many leds one transformer will power, will using more than the prescribed amount of leds per transformer result in their being dimmed somewhat, which may not be a bad thing for house lighting for example. As you can see electrics is very far from my strong p
  8. Thanks, Initially I want to try the shim method so if anyone can let me know just how and where to place the shim (and its size/thickness) that would be great.
  9. Apologies as I know this has been done to death but maybe some kind soul/s might condescend to help me out, what are the basics of the plastic shim remedy for the vee gap in set track points? If I am running short wheel-based wagons say or some steam tenders there is what appears to be a tendency for wheels to drop into the gap in that area causing derailments, I recall people fixing that with the shim method but I need the size/type/thickness of plastic and exactly where to place it, also advice on the type of adhesive to use please if possible.
  10. Sorry about the delay in responding, I also had some domestic advice regarding trying the pestle and mortar idea and might give it a go, nothing to lose on it anyway, thanks.
  11. Great stuff, I obviously did not recall the mixed gauge sizes correctly, hard to know what people consider a large layout but it looks like an awful lot of ballast will be needed hence the interest in bulk supplies of the material. The sieve I have used so far is giving me roughly the same size as the Hattons 00 size ballast which will include some finer stuff given how small the flour sieve holes are, am I being too greedy in trying to extract more material from the IKEA bags as I am getting about only 25% of usable material from those.
  12. I have never done any ballasting before and I ordered some 00 ballast from Hattons but haven't used any yet, however I came across a thing called pumice stone in IKEA (used for propagating plants apparently) and saw it could be used as ballast. The difficulty is a lot of the product is too large to be realistic as 00 gauge ballast so therefore needs to be sieved. I have already used the kitchen flour sieve but am wondering if there is any other type of sieve that might allow for a slightly larger (but realistic) fall through as the amount of stuff getting through the flour sieve i
  13. Thanks Rab, Funny enough that's the first tie I have been aware of that typo, your poster gag is very good.
  14. Again many thanks for all your interest and responses.
  15. Thanks again to all respondents, some good ideas there.
  16. Thanks to all for your very prompt replies, the photo of the Presbyterian church is especially evocative but perhaps not quite what is needed, the KINGSWAY Bethnal Green model is probably too grand but their St Judes model looks appealing both in size and aesthetics. I have never used card models other then superquick or Metcalfe (which I have a preference for), can you only get KINGSWAY from the manufacturer and in general how would they rate in terms of construction difficulty compared to Metcalfe?
  17. Hi, Anyone any ideas where to buy a cardboard 00 kit for a non-rural church, I have bought and built the Metcalfe version but now it does not seem quite right in my setting which is late 50's to early 60's. I intend to site this amidst a semi-industrial area with quite a few Metcalfe red brick houses forming a terrace so the church needs to be less of a pastoral design that what I believe the Metcalfe version is.
  18. Thanks HLT, Anyone any idea if replacement corduroy pads can be sourced and where please?
  19. Managed to dismantle the CMX after a struggle with the centre cap, I found this difficult to unscrew and was worried that something unknown inside would shear off. However upon its release it proved to have a metal tapered spike for sealing off the bottom opening which allows liquid to drop on the cleaning pad, after a decent cleaning of all parts the liquid was being dispensed. Even with all parts re-assembled there remains a resistance to unscrewing the centre cap to allow for drip release to the pad, pardon my ignorance but what is causing the resistance to opening t
  20. Thanks HLT, I did mention originally that my cleaning fluid was nail polish remover which seemed to work well with no discernible residue on the track anyway, I will give this problem a bit more attention this week and hopefully no lasting damage has been incurred.
  21. Thanks to all, The corduroy pad seems okay, it's just the dispenser seems to be stuffed, it was indeed left idle with fluid inside so hoping nothing was damaged but presumably they are built with the understanding that fairly strong chemicals would be used in them? I will do a more detailed investigation with a view to dismantling the dispenser if possible and cleaning it out. I was of the opinion that the brass valve in the centre of the unit controlled the flow rate of the liquid so by regulating this valve open or closed determined how much of the liquid flowed on to
  22. Hope this is okay to post here... My CMX track cleaner has been laid up for a while, as I have myself, so getting back to a re-start on my layout I find the cleaning fluid is not seeping onto the cloth pad which is remaining dry so it is ineffective, is there a way to check that the outlet which allows the liquid to release onto the pad is perhaps clogged up through non-use, or have I not done something very simple. The CMX unit, while being circa 5 years old, has not been in constant use over that period and I am using my wife's nail polish remover as the cleaning flu
  23. Good luck with that, I spent ages searching for a suitable pen/marker to produce white lines on quite a substantial amount of home made platforms, after trying various types of tape I finally sourced a white marker pen in a local arts shop, probably should have started my search there originally. My layout is 00 and after 18 months of being used the lines look quite good, I presume they are never really meant to be a pristine white anyway?
