Hi, After much searching and pleading on various forums the kindness of someone on RMWeb resulted in the delivery of a copy of a copy of a Cowans Sheldon GA drawing of a 70ft turntable. This will allow a model to be built in due course for Bankhall. Then I noticed that it states on the drawing that the rail on the table is XXft/yard flat bottom rail. Unfortunately the figure for the weight of rail is on a fold in an earlier version of the drawing and cannot be deduced accurately from the print in my possession. Under magnification, it may be 30lbs/yard but more probably 80lbs/yard, although even this seems light. Does 80lbs/yard seem reasonable or does anyone have any better idea what it might actually be? And if so, what code of rail might be used to replicate it in 4mm=1ft scale or would it be a one-off section used on Cowans Sheldon turntables and not something that was ever used on running tracks? I'm bemused . . . but confident someone will know the answer. Cheers, David C |

Mick, I'm wanting to build a smaller turntable - I have no need for Pacifics at Bradford North Western. Can you point me in the direction of a plan for a smaller one suitable for an LMS ex-LNWR location? Ian

As Mick Nick told me, it's out there somewhere, you just have to keep poking until someone delivers. HTH, DC |

Otherwise you could have someone going to a lot of trouble to find it for you, not realising that the answer has already been posted on some other group. Martin. |

Hi, I attach copies of the drawings that I have. I confess these came to me from others so I presume they will be sympathetic to your request for the information they contain. 1570_171952_270000000.png  Cowans, Sheldon 70ft turntable (Click the image above to see it in the Image Gallery, then click and click again to see the original full-size image.) ATB - and good luck with getting a model of the 70ft table for your layout. David C PS I have some scans of 65ft Cowans Sheldon TTs as well and if these are of interest to anyone else just ask. (David also attached a Skinley drawing of a 70ft model turntable. Skinley drawings are available commercially from: The Sussex Modeller, 20a Rowe Avenue, Peacehaven, East Sussex , BN10 7PF, tel: 01273 581265. It has therefore been removed for copyright reasons.

Hi David, Hope this isn't "teaching grandmothers to suck eggs"  The "code" of a rail is the height in "thou" - I prepared a table that was published in MRJ some time ago showing the code against the equivalent prototype lbs/yd figure - unfortunately I can't find the original of that, but I have a table showing the equivalent sizes in 4mm & 7mm for the various dimensions quoted in the BS spec. (just converted it to a word document as I find I can't attach an Excel spreadsheet! best wishes Richard Jones 1763_180527_180000000.png  |

Hi Richard, Many thanks for that.  just converted it to a word document as I find I can't attach an Excel spreadsheet!It's better not to attach files in DOC, XLS, and similar Windows "business" formats as many members will not be able to access them (me included  ).PDF is a suitable alternative which most members will be able to read and print out if required. However, I've converted your table to a format suitable for the Image Gallery and inserted it in your message that way. regards, Martin. |

Hi Martin, Fortunately I can access a full copy of Acrobat (as opposed to just a reader), so I'll convert anything else to pdf in the future best wishes Richard |

PS, Does anyone know what Singleton (West Sussex) turntable was like? I understand it was removed by the Southern in the 20's (re-used elsewhere?). I have seen photos of Chichester and Lewes tables where the whole deck was boarded over, so that the "well" is not visible. Presumably The Brighton had a standard design? best wishes Richard |

Richard_Jones wrote: PS, Possibly it was made by Peco:-) A question regarding 'powered' TTs in th eUK. I have seen pictures of some TTs with large tanks under the bridges and have always assumed that they were filled with compressed air from the Westinghouse. Someone has suggested that it could also be a vacuum tank, as vacuum brakes are/were much more common. Another writer then chimed in avowing that the TTs were powered by a small donkey engine, drawing its steam from the steam lamce cock or similar. This I find a little dubious. Does anyone know? Thanking you, Roger |

Photos of locos connected up on such turntables exist, but as I'm not in my library at the moment I can't quote chapter and verse with examples. Air braked locos and trains weren't that common in the UK in the days of steam. Cheers for now John, from 33820 St Ciers sur Gironde, France |

Hi John and Roger, I fairly certain the Brighton turntables of that vintage would have been manual - they were on 45' and certainly on the Lewes one I can't see any sign of any hose connections - I try the Brighton Circle as well to see if that approach generates any answers. best wishes Richard |

Thanks to Richard Jones for the table of rail codes. If you look back at the thread you will see that Mick Nick had already advised by looking at his copy of the TT drawing that the rail was 80lbs per yard and therefore code 69 (or more realistically in terms of availability code 70) is what I will require. Now to see if I can persuade one of the suppliers to let me have the 2 x 70ft (or 12 real inches) of code 70 rail that I will need when (one day!) MetalSmiths produce their promised kit for the 70ft Cowans Sheldon TT. For anyone interested, PH Designs have kindly produced etchings for the Ransomes Bankhall breakdown crane so these esoteric bits and pieces for my layout are gradually coming to fruition. Cheers, David C |

Richard: we have a constant problem with Brighton turntables -as there seem to be very few photos that show much and almost no plans. However, if you check out the Brighton E-group there's talk of John Ritter having something approaching a plan that Barry (Pulborough) Luck and I are both interested in seeing - so hopefully we might get a glimpse if John can find a way to send it from Oz. Also check out Metalsmith's website - http://www.metalsmith.co.uk/4mmscaleCowansSheldonPre-Groupingturntable.htm - they appear to be mainly pre 1922 Cowans Sheldons - but I don't know who made B'ton ones.

If you cannot print out a copy of the drawing from the earlier posts to this thread, PM me and I'll scan my copy for you which may be clearer. Sad to say Metalsmiths are still showing no signs of releasing the kit for this TT. Hope springs eternal . . . David C |
