41. Timber shoving
... long timbers than others, it is obviously stronger. The LNER and the ER of BR from photos and in the later case observation did seem reluctant to used more long timbers than it thought strictly necessary. The picture below is of a Flatbottom D-9 taken around 1960 and only uses long timbers under the special baseplates, the 3 beyond the wing rails, whereas the standard BR practice was to use long timbers up to and including the one beyond the rail joints ala GWR practice. 2151_011202_320000000.jpg Note that the diverging road is Bullhead. Below is a Templot version of it. 2151_011213_250000000.jpg Regards Tony. posted: 1 Mar 2017 19:44 from: Martin Wynne Hi Tony, Here is the FB timbering chart from BRT3. This refers to straight-planed (i.e. semi-curved) switches, so this would be for the original inclined FB-109 replacements for bullhead. You may like to see how this compares with your D-9. 2_011355_290000000.png Comparing this with the standard REA bullhead turnouts in Templot, you will notice that Templot is ...
... will be reappearing in the Templot Companion in due course, properly updated for Templot2 with new diagrams and videos and explanations. But not yet. p.s. The hobby was massively ill-served by an article in MRJ about 20 years ago which mixed up "straightcut" switch planing with the geometry of straight switches. All switches can be either straightcut or undercut planed (or chamfered or other) regardless of whether they are straight, semi-curved, or curved switches. Martin. red_pointer.gif These notes apply to UK-pattern bullhead track only. Setting the Curved Stock Rail The diagram below shows the position of the set (bend) in the turnout-side (TS) stock rail, which matches the planing angle on the switch blades and is needed to ensure a correct track gauge through the turnout road of the switch. Templot puts a mark across the curved stock rail at the position of the set, as shown below (for a left-hand switch). stock_set.gif In Templot the set is slightly in advance of the tip of the ...

"The equipment comprises two mobile and steerable radio telescopes with parabolic reflectors of 25 metres aperture designed to be capable of operating at high efficiency at any wavelength from several metres down to 10 centimetres. The radio telescopes can be moved along double sets of railway tracks placed on two of the runways of the former Defford airfield. The tracks extend to 750 metres from the intersection, and the baseline joining the radio telescopes can be set along any azimuth and have any length up to the maximum separation of about 1000 metres."© extract from 'Royal Radar Establishment, Malvern (Reports of Observatories)' in Quarterly Journal of the Royal Astronomical Society, Vol. 7, p.232. ...
44. Cutting Rail
... to make an isolation gap cause the rail to kink (not the act of cutting it itself), or will it stay put well enough? Cheers Richard Richard, I try to pre-bend 7mm scale rail to the curve required before laying so that breaks in curves don't dogleg. If you just spring the rail into position and rely on the chairs to hold it in place on the curve, then the rail will "uncoil" when you cut it. Code125 rail has a fair spring in it- certainly the bullhead rail does and I would think flatbottom rail would be even worse. Sometimes you can't pre-bend the short section at the end of a rail, even with a rail bender, so you might have to cut the rail overlength before bending, then cut off the short straight bit at the end.

... , rather than a plan view. (Or am I showing my stupidity?) Bill On reflection that did not really mean much. Am I right in thinking that if you ink the rail, then file it so that the shiny bit looks like the orange part of the diagram, you will have filed half way through the rail at the tip? Bill posted: 1 Oct 2010 14:45 from: wcampbell23 It's not a plan view but elevation- where it is labelled "inked rail" is the web of bullhead rail. Bill Campbell posted: 1 Oct 2010 15:57 from: Nigel Brown So the idea is that the bit at the end where you are filing through the web is equal in length to the next bit where you are filing the top and bottom but not the web. Couple of thoughts:- a) Is this correct? Only if the web is half the width of top and bottom. No idea if this is true on the prototype, but do wonder if it's always true on model bullhead rail ...
... topic: 492 Making precise bends in bullhead rail posted: 14 Jul 2008 20:59 from: Martin Wynne Here's a simple idea which costs nothing and is a good way to make precise symmetrical bends in bullhead rail. It needs a bit of practice to know how hard to tap! 2_041840_270000000.png 2_041828_140000000.png Hopefully the diagrams are self-explanatory. Just two bits of rail about an inch long laid side by side with a gap between. The smaller the gap, so the harder you need to press/hit, but the more precisely located will be the bend. Make sure the rail is exactly square across them before making the bend -- a sheet of graph paper underneath helps. regards, Martin. posted: 14 Jul 2008 21:05 from: davelong Worked perfectly for me.

... topic: 2800 Help for Someone new posted: 5 Dec 2015 09:27 from: BigAndy Hello all, This is my first posting on here and I really am very new to understanding Templot. I am currently modelling Glasgow Queen Street in EM circa 1988 and a very good friend of mine, who has a computing background, very kindly learned how to use templot and then drew out the trackplan for me. However, It has been drawn in Bullhead rail and I need to convert this to Flatbottom rail in order to crack on with tracklaying etc. I originally posted on RmWeb re this and was directed here by Martin Wynne, who has correctly stated that the difference in construction of FB turnouts compared to BH turnouts, is quite different. I apologise in advance for being semi computer illiterate and need instruction at a very base level- don't worry, I won't be offended if you have to word it for dummmies!!3095_050425_020000000.jpg I've attached this shot as it shows the trackwork and turnout types. cheers Andy posted: 5 Dec 2015 14 ...

... but I've seen some images of Irish 3ft gauge with BH/chaired track. I was wondering if anyone knew anything about it. This is Ballycastle http://www.ballycastlehistory.com/railway-world-november-1979.html I've also seen it on CDR, L&LSR and T&D photos. Would this have been handed down stuff from standard/5'3" railways?

Jim. posted: 11 Jan 2020 06:18 from: DerekStuart Morning Jim Are you sure Ffestiniog uses different rail cross-section? I seem to recall that they received a donation of ex BR BH rail. I'm sure there was a conversation here in which it was said that the wheel treads were the same as the mainline- just that the diameter of the wheel was smaller. Of course, I may be entirely wrong on that ...
... topic: 3797 Bullhead fishplates posted: 11 Oct 2020 23:37 from: Rob Manchester Hello, Is there any pattern or reason behind the use of short 2-bolt fishplates for joining bullhead rails? I remember them being mentioned in a topic a while back but a quick search didn't find it. Were there regional variations in their use? I am guessing they would not have been used in faster main line settings or in more recent times. "British Railway Track" does mention the use of these shorter 9 inch fishplates and comments that 4 bolt fishplates were the best option. Here is a poor quality pic( of GWR origin?) 2001_111830_180000000.jpg Should we be putting these on a few lightly used sidings? Rob posted: 12 Oct 2020 00:08 from: Matt M. Hi Rob. These were popular pre WW2. The Idea is they leave a shorter unsupported length of rail at the ends of the panels. This was supposed to counteract dip which is an issue at rail joins which collect excessive wear and damage as the ...

I'm particularly interested in the standard turnout and the curved turnout. Hi Jim, I've had one of the BH straight turnouts on my desk as a paperweight for years. I will get a matching template done for you -- I seem to remember doing one years ago, but I can't now find the file. For a commercial RTR offering it's really not bad at representing UK bullhead practice -- which rather rubs salt in the wounds of those stuck with their "00/H0" range. The crossing angle is 8 degrees (1 :7.1 RAM). There is a long entry-straight to the V-crossing -- the base moulding for the V-crossing is symmetrical (equalized timbering) so that the same base moulding can be used for both hands of turnout and for the diamond-crossing. In fact the left-hand turnout here has a right-hand V- ...

Hi Ewerthon, It is probably the stainless steel bullhead rail available from DCC Concepts, see: http://www.dccconcepts.com/track-trackmaking-parts/dccconcepts-track-and-trackmaking-parts/rail-bullhead-4mm-scale-stainless-steel-l -960mm-10-pack The problem with stainless steel is that it is difficult to solder, needing an aggressive acid flux and higher temperatures. Which must then be cleaned off to avoid future corrosion. This is especially necessary with electrical connections. In fact any form of acid flux is generally ...

Having printed out and stuck down the first set of templates on the baseboard, a second attempt at printing one of the points with flat bottom rails, it stubbornly refused to print the rail foot, remaining as if bullhead.

Your template no. 35 is labelled "bullhead". It is however set for flat-bottom rails and is printing as such here. Note that only background templates can be printed with a rail foot (blue-grey rails). The control template cannot yet be printed that way*. Did you perhaps have no. ...

This uses an H switch and 1 in 20 crossing, making a very long turnout indeed. There's a track diagram in Robertsbridge (RVR) station building with all the radii on it! posted: 8 Oct 2013 01:19 from: Martin Wynne Hi Roy, Many thanks for the pics. It's quite unusual to see such a long turnout being installed in bullhead track nowadays. Do you know if it is a new 1:20 crossing, or second-hand recovered from elsewhere? The reason it is so long is because the two radii are so similar -- 142mm/ 146mm. That's a difference of only 2.8% so I'm quite surprised it isn't much longer than a 1:20. A quick check suggests such close radii would require about 1:40. Of course no such bullhead crossing is available. An H switch would normally be natural at about 1: ...

This will be all bullhead on wooden sleepers. I dont want to go to 21mm, as theres too much plain track to build( and stock to convert), so have decided to use 00-SF. its a decision I didn't take lightly what would people now consider as the pre-eminent way to build 00-SF points( I will use C&L for plain track). (a) Copperclad with half chairs( using vero pin to raise rail) (b) Brook-Smith, again with half chairs on ply (c) all plastic construction( how do we handle the lack of flange chairs etc) (d) ply and plastic chairs, again we have a lack of crossing chairs for 00-SF (e) Combinations Paticulary as copper clad is getting more and more expensive and actually looks like it will exceed ...

Hi Brian, Looking good. Thanks for posting it. Normally machined flares are used for heavy-rail flat-bottom track, and bent flares are used for light flat-bottom rail and bullhead rail. It's rare for bullhead track to use machined flares. Consequently there is only one setting for the entire template. If you want to mix the types of flare in a single formation, it's very easy -- simply split the relevant check rails out as a separate partial template. That way you can also change the individual flare lengths, etc. Splitting out individual rails as separate partial template(s) is the normal way in Templot to mix different settings within a formation. However, I strongly recommend that ...
... a single file, if you have zipping software. Secondly, 'FB', I didn't know there is a difference. I've been opening up T'2 and setting the scale for P87 and working from there. After looking around a while, and not finding anything, I'd like to know how you did that. If it will make a difference in the templates I will use on a scale railroad, I think I do that from now on. And, should I convert what I've done so far? Traditional UK track used bullhead rail section supported in heavy chair castings. Modern UK track uses flat-bottom rail (as does most of the rest of the world): 2_130841_170000000.png Templot defaults to bullhead rail, as this corresponds to the vast majority of hand-built model track in the UK. If you are modelling flat-bottom track it is very helpful to have the rail foot edges shown on the templates, otherwise the model rail foot obscures the rail lines. It's important to set up the rail section dimensions to reflect accurately the model ...
