  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.
