Does anybody have any information on the dimensions of Irish 3ft narrow gauge track? Specifically sleeper dimensions and spacing. A templot box file perhaps. Not really bothered about the scale, just something I can get accurate sizes from. I've tried guessing from photos but I'd prefer to know for sure. Thanks in advance Ian |

Hi Ian I have asked this question on here and several other forums and have never got an answer. What I have in my round tuit box is some photo's of some Isle of Man turnouts which need sorting and trying to turn into a template. I think this will be the only way to get any info on 3ft trackwork. The preserved railways in Ireland are using recycled standard gauge (5ft 3 ins)componets regauged to 3 foot. The Ilse of Man being the only source that i know of that still has original 3 ft track, I just hope it is not too disimilar to the Irish stuff. Cheers Phil |

The usual dimensions for Irish 3ft gauge are: sleepers 6ft long. sleepers 9in wide. spaced at 2ft-6in centres. rail 60lb or 65lb / yard flat-bottom (sometimes called "contractor's rail", used by the contractors building the line). Often spiked directly to the sleepers without baseplates. rail lengths 15ft - 30ft, often mixed. Generally the companies sourced track materials from wherever they could, sometimes second-hand, so the lines were a mixture of all sorts after a some years of repairs. There is a Yahoo group with useful information: http://groups.yahoo.com/neo/groups/irish_three_foot/conversations/messages regards, Martin. |

I suspect it varied a bit by Railway. Patterson gives the dimensions for the West Donegal (later CDRJC) as 45lb rail, 27feet long. Sleepers 6 feet long and 8" x 4" in section. Sleepers at 30" centres except at joints where they were 22". There may be similar details in his other books. | ||

Thank you all. One supplementary question; is there some way of converting the rail weight into model code? For instance I intend to model the CDR in 5.5mm scale, would 65lb/yd have an equivalent, like Code 75 or Code 100? |

Hi Ian, 65lb/yard flat-bottom rail is 4.11/16" tall. At 5.5mm/ft that scales to 0.085", i.e. Code 85. 60lb/yard flat-bottom rail is 4.1/2" tall. At 5.5mm/ft that scales to 0.081", i.e. Code 81. Code 82 and Code 83 flat-bottom rail is available. regards, Martin. |

p.s. Ian, Karlgarin Models have some specialist rail sections intended for narrow-gauge, see: http://www.karlgarin.com/whatsnew.htm Martin. |

And there's Andy May's page on the S Scale web site with the prototype dimensions of a huge range of rails. http://www.s-scale.org.uk/rails.htm Jim. |
