Hi All, due to the change of plan the sidings at Soddingham are going to have mostly flat bottom rail ('coz I've already got some!). The question is : would points in the yard have plained or bent check rails/vee ends? (It's safe to assume that these have been re-laid pretty recently). This photo shows bent ones on a main line Bent Check Rails, but then it is generally assumed that all flat bottom points have plained ones. Clearly the assumption is no wholly correct, does anyone have a photo of a set of points in an early 80's yard with bent ends? I just want to be able to say to any nit-pickers that bent ends are, or aren't, ok. The reason I ask is that plained ends don't somehow look right in sidings. The second question is : can Templot change an existing template from bullhead to flat bottom? And finally, it's only taken a mere four years, but here's an actual set of points under construction at my 262_170747_400000000.jpg Cheers Richard |

(It's safe to assume that these have been re-laid pretty recently).Hi Richard, For yards and sidings owned by BR and relaid in FB since about the mid-1950s I think you should assume machined flares, unless you have evidence to the contrary. BRT3 (1964) discusses this on page 108 and suggests even the first FB-109 designs used machined flares. Apart from the difficulty of bending FB rail, the main reason for doing this was to avoid the need for special handed baseplates at each end of a check rail, and that then also allows the angle of flaring to be adjusted according to the line speed. For privately owned sidings and yards, where industrial-pattern trackwork is usually supplied by contractors, bent FB flares are probably more likely. Usually these are in lighter rail section which is easier to bend. This picture from Mick Nicholson of Brayton Junction, showing bent flares: 1571_031811_110000000.jpg shows I believe an earlier LNER FB design (Mick?). The big four companies were conducting many experiments with FB track before nationalisation, and there were several designs. The FB-109 design was standardised by BR in the early 1950s, using machined check rail flares. Other companies had different ideas, this is CIE practice at Dundalk in 1986: 2_170837_040000000.png regards, Martin. |

Hi Martin, thanks for that - plained it is then! And the date explains the weird dummy in the photo! Cheers Richard |

p.s. Richard, Michael Davies posted a fine collection of 120 detail pictures of FB track in a yard: http://85a.co.uk/forum/gallery_view.php?user=1679#gallery_top As far as I can see they are all machined flares: 1679_261346_190000000.jpg 1679_261331_320000002.jpg (Large hi-res images available by clicking the original size links.) regards, Martin. |

Hi Martin, thanks for that - just the job! Anyway, they are easier to make - always a good selling point Cheers Richard |
