... see whether I could actually build a turnout and secondly to see if it is something that I will derive pleasure from. There would be little point to purchasing a software that produces beautiful templates if your not going to actually construct them. As I mentioned in my earlier post, my first attempt with the SMP kit was a failure, don't laugh but I'd used the track gauges incorrectly so my 00 turnout is almost TT gauge. Also, I'd made it harder on myself by substituting Peco flat bottom code 100 for the supplied bullhead. I had the idea of connecting the turnout when completed to some Peco track that I've had kicking about since childhood days. You'll recognise that at forty thirteen I'm relatively new to model railways. I'm not in any particular hurry to get track down and trains running but I have it in mind to build my own track and in this regard need to increase my knowledge base. I think I'm okay with the principles behind the terminology for say a 1:6, 1:7 or 1:8. But the ...

Hi David, That looks excellent. It's not often you see the spacer blocks and bolts modelled. But I'm a bit worried about the sharpness of the nose. Unless it's an optical illusion, that looks almost a knife edge. For traditional bullhead the vee nose is blunted back from the FP gauge intersection to a nose width of 3/4" (GWR 11/16", FB 5/8 "). Here's an excellent pic from Mick Nicholson showing an almost new bullhead crossing. You can see how the vee nose has been blunted back from the intersection, and also profiled down below the level of the wing rails to match the coning angle on the wheels. The nose is always over the A timber and enclosed within the built-up A ...
... topic: 1110 About the most "bridge" chair. posted: 22 Apr 2010 22:08 from: Ewerthon Mota Hello folks, what chair makes the bottom of the rail be most apart from the top of the timber? The photo bellow show more cleary the aspect of bridge that this rail has, something that flatbottom don t have, and that make bullhead so special: the distance between the rail and timber is larger in bullhead case. But what chair is thickier on base to provide the largest clearence? I saw a lot of types in exactoscale, C&L and scalefour society but no measures at all. I ll make 1:64 (s scale) and 1:32 (gauge one) layouts but the indecision about chair is stopping me to progress. 1871_221622_490000000.jpg posted: 23 Apr 2010 01:15 from: Martin Wynne Ewerthon Mota wrote: what chair makes the bottom of the rail be most apart from the top of the timber?

... topic: 2950 inspection/ash pits and turntables posted: 17 Dec 2016 16:16 from: gibbard d Hi everyone in a steam shed scene what type of rail would be used on inspection pits and ash pits? would it be bullhead rail fitted to chairs that are bolted to metal beams or flat bottom rail bolted directly to the supporting beams? I haven't decided yet whether ill model an old BR shed or a preserved steam shed, would there be differences? also the same questions regarding turntables. the main yard area will be constructed from bullhead rail using c&l chairs, if the pits use flat bottom rail are the rails compatable or would I need to make custom joiners or even solder the rail ends together? posted: 18 Dec 2016 23:03 from: Tony W I have seen both Flatbottom and Bullhead rail used for ash pit/ inspection roads. Bullhead would be more typical in steam days, however the supporting way-beam would be made of timber in the same fashion as on bridge decks using bridge chairs, ...

Looking on internet I didn t find much, however I found this interesting discution going http://www.rmweb.co.uk/community/index.php?/topic/39955-20-turnout-in-ho-gauge/ There was made a longer than f20 turnout?

... topic: 1324 Turnout Stock Rails posted: 1 Jan 2011 08:02 from: polybear Hi all, I'm in the process of making a B8 R/H Turnout using Bullhead rail; it's 4mm and using copperclad sleepers with Masokits etched brass chairs. My question is: what is the best way to accommodate the tips of the switch blades where they meet the stock rails? Put a "set" in the curved stock rail? And if so should I do this in the straight stock rail also? Or go for joggles- in one or both rails? What are the best ways of creating both these methods please, and how to judge when it's the correct amount of "set" or "joggle"? My interest lies with ex-LNER/LMS, late 50's to early 60's. However, my first priority is for good reliable running, even if it means using a technique which wasn't commonplace at this time (I think joggles were more a pre-grouping technique?) Many thanks.

... topic: 3309 Switched Diamond with Slip Road in Bullhead posted: 20 Jul 2018 08:38 from: Jim Guthrie I'm helping someone out fine-tuning his design for a layout in 0-MF and there is a ladder of diamonds on a curve where the crossing angles are over 1:8. So the diamonds should be switched. But I have to place slip roads on two of the diamonds and I wonder if this had been done on the prototype in bullhead days. I'm interested in how the switches for the slip and the switches for the diamond co-existed. Jim. posted: 20 Jul 2018 08:53 from: Raymond There were, if I remember correctly, switched diamond slips at Snow Hill but I am unsure if such things were used on main running lines. I drew up Snow Hill in Templot some years ago including the switched slips in Templot. Unfortunately I do not have the plans any longer.

... topic: 3729 Flat bottom rail crossings posted: 30 Jul 2020 21:42 from: Paul Boyd Hi all I'm about to embark on some flat bottom track for the first time, and am stumped on how the two rails in the crossing join! Does everyone only ever use bullhead??? The photo shows what I'm building (my own photo), as well as an enlargement of the crossing nose. Do the point and splice rails simply taper and join together so that each forms half of the blunt nose? That's how it appears in the enlargement, but the apparent line down the middle may simply be uneven rail wear. Any other hints and tips on working with FB rail will be appreciated. I can see I'm going to have to make some grooved bending and filing jigs for a start. I'm using Peco IL-1 code 60 FB which may be a little light, but the rail foot width allows for the 0.5mm flangeway gap without any filing. Or did the prototype have to reduce the foot width to allow correct ...

The rail on the right is Scalefour stores mild-steel bullhead (4mm), the middle rail is C&L's new HiNi 7mm bullhead, and the right rail is "unknown" nickel silver 4mm F/B rail.

... topic: 3387 Modelling GWR loose heel switches in 4mm posted: 13 Feb 2019 13:32 from: madscientist I have always built semi Curved bullhead track, but now I have to build some GWR( WR) track work and this means loose heal switches and joggles in 4mm,( 00-SF) other then a slightly different geometry, is there any practical difference between loose heal and fixed heel switches. I would have thought both would have been made from a continuous piece of nickel silver track with cosmetic fishplates Am I correct here, or should the switch be physically cut at the heel?( ie between the tongue and the lead) secondly, reading the scalefour notes on loose heeled switches, there can be an issue with the stock rail to switch clearance with the switch is open, this would be exacerbated in oo-sf, is this the case, would it be better to stick with fixed heel? any hints on how to make the Joggle, I havent worked out reliable way to do this( 0.2mm joggle) ...
... That's easy to do -- starting with one of the half-diamonds as the current/control template, just click the tools> make diamond-crossing menu item. I think if you change the angle to be the average of the two existing angles you will find that you can get everything to fit. If necessary you can use a different radius at each end (keeping the peg in the centre at CTRL-3 while you do it). You have used a mix of straight and REA semi-curved bullhead switches. For your prototype in the 1980s you ought really to be using flat-bottom turnouts for the running lines. There is a range of curved switches for BS-113A flat-bottom turnouts in the list at template> switch options... menu item (scroll down the list). Changing the switch will alter some of your alignments slightly, but only enough to need small corrections. Of course you can build flat-bottom rail on the bullhead templates if you prefer, and you may feel that ...

The switch toe does look a bit too fat for comfort, as though a wheel might bash on the end. But it ought to be easily thinned with a file. Nigel posted: 14 Sep 2017 20:12 from: Rob Manchester Hi, Sure these will be a good seller for Peco. Anybody heard about pricing for the new bullhead turnouts? The FB ones are around the £13-14 mark in most discount shops. Guess they aren't likely to be near that with new tooling costs etc. Who are they made by? Do anybody know how many companies actually MAKE track rather than badge other peoples products. The best looking RTR track I ever used was Tillig HO which is also available in semi-kit form that allows some deviation from the nominal radius when laying. I think model shops and toy fair dealers will have many boxes of Peco ...
... topic: 3587 Peco 00 bullhead turnouts posted: 21 Dec 2019 21:08 from: Bob Fuller I am a newbie to Templot, so I'm working my way through some tutorials. Attached is a box file of my attempt to recreate PECO's new(ish) code 75 Bullhead points in 00. The PECO specs only give length 259mm; frog angle 12 degrees; and radius 1524mm. I appear to have the correct length and frog angle in my template, but the radius is not correct. For the switch settings I have used the "custom: 1:35 Peco-only" selection from the list. What do I need to adjust in my turnout to achieve a 1524mm radius? And which radius measurement does the PECO spec of 1524mm relate to? Is it nominal switch-curve radius or turnout-curve radius?

I have read vague references to BRT7 "Switches and crossings". There is a PWI book listed for "switches and crossings in flat bottom rail." Of course, like most others I am interested in bullhead. These books aren't cheap so I wouldn't like to pick one at random.

Martin. posted: 1 Jan 2018 07:55 from: roythebus Thanks for that info Martin. Would such long switches be prototypical should have been the next question! There's some pretty long switches at Ashford on the HS1 line set out for 300km/h running. I was half-tempted to make a 1:50 to see what it would look like. I doubt if it would look right in bullhead rail though. No doubt the prototype would use cast vees. posted: 1 Jan 2018 11:42 from: Martin Wynne Hi Roy, The longest crossing normally used in bullhead was 1:20, used in F-20 turnouts. The SR experimented with a longer G switch in longer turnouts, but the high-speed lines for which they were needed would have been among the first to be converted to flat-bottom. So not much used. regards, Martin. posted: 1 Jan 2018 12: ...
