... topic: 3168 3-way tandem turnouts in 218a posted: 2 Jan 2018 13:36 from: Martin Wynne I have been trying to automate at least partially the creation of 3-way tandem turnouts. This new function will be in 218a update shortly. It's not perfect, but hopefully will be helpful for those struggling with them. A scruff video clip: http://flashbackconnect.com/Default.aspx?id=KA3AFzb5P7AEkiMqzNa_LA2 I'm leaving the single-sided tandems (trickier to do) until I see how this goes and any issues which crop up. It's more or less ready, but I can't release 218a until I have done something about this page: http://templot.com/companion/3_way_tandem_turnouts.php regards, Martin. posted: 3 Jan 2018 07:01 from: Dave Summers This looks like another very useful feature which will only enhance the flexibility of Templot for those of us that struggle to achieve and maintain a degree of proficiency! Thanks Martin posted: 3 Jan 2018 11:21 from: Judi R Martin, that looks ...
... topic: 242 Middle Crossing on Tandem Turnouts posted: 18 Nov 2007 18:09 from: Mik Raybould Hi I'm trying to build a tandem turnout, B6 and A6 oppsite hands. But get stuck on the middle crossing. The videa uses an A4.5 crossing. How do you work out the middle crossing angle/ratio? My resultant curve are 1331 and 3341 mm. Mick Raybould posted: 19 Nov 2007 13:01 from: Andy B Hi Mick, I'm about to do my first tandem- so I've been carefully studying Martin's videos. Watch it again- Martin creates the centre crossing initially using a 1:4.5, but after placing it in the correct position he changes the the crossing angle to 'any angle' and manually adjusts it. 6 mins and 31 seconds in to the video is the critical point! Andy posted: 20 Nov 2007 20:30 from: Mik Raybould Thanks Andy. I've worked out what I was doing wrong- I forgot to put the- sign in front of the curve radius on the turnout used ...
... and curve it to look like a left hand point then superimpose a left hand point on top in the normal manner. regards Alan posted: 15 Feb 2015 19:00 from: Martin Wynne Alan Turner wrote: The first thing to understand is that whilst it looks like you have two left or right hand points you in fact still have a left and a right hand point. It's just that it is curved so that it looks like the opposite hand. Hi Alan, That's not strictly true, a single-sided tandem can easily have both turnouts of the same hand. In fact that's normally the case where an outer road is the main road: 2_022021_130000001.png The same can apply to a 3-throw turnout, although in that case single-sided versions are quite rare. Derek, here is a sequence of posts showing some of the constraints in creating a tandem turnout: topic 2394- message 16119 Unfortunately tandem turnouts are not straightforward, and you do need to be reasonably confident with Templot to produce a usable result.

... topic: 1084 GW tandem turnout posted: 22 Mar 2010 12:06 from: Phil O Hi All Does anyone have any info on how the GW would have arranged the timbers under a tandem turnout? I have had a look in David Smiths book GWR Switch& Crossing practice and can find no help there. Below is the turnout which I would like to sort out the timbers. 38_220704_280000000.png TIA Phil Last edited on 22 Mar 2010 12:08 by Phil O posted: 23 Mar 2010 21:26 from: Paul Boyd Tricky question! This is the way I do it, which may be right or wrong. I work on the basis that each element of the turnout is made up of standard components, i.e., three crossings and two switches. On the prototype, the timber spacing within each component was pretty much fixed so that the special chairs would fit so that's what you have to base the overall timbering on. So, starting with the switches, you know what type of switch you're using and where the rail joint ...
... long time ago. In practice everything depends on the actual circumstance -- the amount of slew and length of slewing zone. Alternatively you can build up what you want using 3 transition curve templates -- easement from straight to first curve; S-curve transition from first curve to second curve; easement from second curve to straight. Use the make transition functions to create the central S-curve (remembering to move the outer pegs to the curved ends while you do it). The disadvantage there will be inserting the tandem turnout and double slip across the template boundaries, leading to lots of additional partial templates. With a slew it is a single template and you can insert a turnout anywhere within it and then roam the turnout into position. If you post a screenshot or .box file it will be easier to suggest the best approach. regards, Martin. posted: 6 Jan 2012 14:53 from: r_wilton Hi Martin.

... topic: 2410 RH Curved Tandem check posted: 19 Feb 2014 18:20 from: Trevor Walling Hello Temploteers, Here is a Double tandem I have done myself to see if I could. I would appreciate any faults or issues being pointed out as I am convinced there must be something I have overlooked. Trevor.

A couple of points: 2_191341_580000000.png There isn't room for wheel flanges on the running rail at A. To be safe in 00 you need about 2 rail-widths clearance, or maybe a bit less in EM/00-SF. Shorten the flare length and/or rail length and/or change to a machined flare on this check rail end to clear: 2_191353_230000000.png The same applies to some extent at B, although just shortening the length a little should be enough. regards, Martin. posted: 19 Feb 2014 22:42 from: Trevor Walling Hello, I had a bit of difficulty ...
... add your indexing suggestions. Please don't start a new topic -- post everything as replies here in this one, so that I know where to find it. Many thanks for your help. Comments welcome as always. regards, Martin. posted: 27 Apr 2009 19:38 from: Phil O Hi Martin I have just had a quick look at the indexing and it looks to be a positive step forward to helping find information especially if the index can be cross referenced to the various forms of terminology used ie. tandem turnouts and three way turnouts, compounds and slips etc. I find when using the search facilities I have known that the answer is there but can't remember the terminology used and have to try the various terms to find what I'm looking for. Also could the scruff video's be added. Keep up the good work.

... Wynne Hi Julian, Thanks for reporting this bug. It's not related to the new version 226c, everyone got that today (released 7pm yesterday). Had you reported the bug a couple of hours earlier I would have delayed the release in order to fix the bug first. That has happened several times in the past -- someone finds a bug which has existed for 20 years and reports it within minutes of a new update being released. I think it's called Sod's Law. There is a significant bug in the make tandem function which no-one else has found in the 2+ years that function has been available. Many thanks for finding it and reporting it. It happens when the starting turnout for a single-sided tandem has a turnout radius larger than the "natural" radius for the V-crossing angle. That usually means having a curviform or generic V-crossing with an angle flatter than the "natural" angle for the switch. In your case a B-switch with 1:8.5 angle (the natural crossing ...
... topic: 1458 Problems with 3way Tandem point posted: 17 Apr 2011 09:54 from: its_all_downhill Hi Temploters, I am having problems with a 3way Tandem point I am going to build in 2mmFS. I have followed Martin's video step by step and am confident up until the place where you rotate the K onto the background template no matter what I do I cannot get this to fit and cannot see where I am going wrong. I have to admit I have no clue when it comes to the prototype and alot of terms in Templot baffle me. I know I should know all these things and terms but I have managed to get this far blissfully ignorant. I would if someone could take a look and advise me where my problem arises and then I can complete this for my micro layout.

90. 3-Way Turnout
... rail (which I can do by bringing the appropriate segment to 'current' and using the mouse.) My problem is keeping the component parts together. An elementary failure to grasp the basics I am sure but the grey matter isn't up to par these days. Robert posted: 22 Sep 2018 14:09 from: Martin Wynne Hi Robert, Welcome to Templot Club. If you have been away from Templot for a while you may not know that Templot can now do most of the work of creating a 3-way tandem turnout for you. See the tools> make 3-way tandem turnout> menu items. But first please read this page: http://templot.com/companion/3_way_tandem_turnouts.php Which like most pages of the Templot Companion has the dreaded" ...to be continued..." at the bottom. I'm sorry, I haven't yet got round to the tutorials on how to make the final adjustments needed. I assumed that by the time a Templot user has got as far as creating tandem turnouts they would know how ...
91. Tandem Points
... topic: 2648 Tandem Points posted: 12 Mar 2015 06:32 from: D Foster I was recently asked for images of the sole plates in tandem points. The first example is at the MRC at Butterely. The blade tips are so close here that I would tend to call this a three way point rather than a tandem. I think that there is a sole plate under the first set of blades- drilled holes in the steel plate are just visible- but there is no sole plate under the second set of blades. 3017_120119_070000000.jpg The second example is at Haworth on the K&WVR. Again the blade ends are very close. Also, once more, no sole plate for the second set of blades. First look includes ground levers, connections and stretcher bars. 3017_120125_080000000.jpg Second look is close-up/edit of both sets of blade ends- and only one sole plate. 3017_120128_550000000.jpg Apologies for hiccups in posting- this is my first attempt... posted: 12 Mar 2015 06:49 from: D Foster Hmmm ...

The missing templates consist of a 3 way tandem turnout created using the Templot menu facilities. I have no idea why they are missing.

Regards Brian 88_271628_560000000.png posted: 27 Jan 2020 22:55 from: Martin Wynne Hi Brian, You are not doing anything wrong. A tandem turnout and other complex formations are typically comprised of several partial templates. You are using diagram mode output there, and in this mode, partial templates cannot be displayed on the sketchboard, or anywhere else. Diagram-mode output works by filling colour between the outer stock rails, one template at a time. If one of those rails is omitted from a template, it can't work. Complex formations such as a tandem turnout are often built up from partial templates where each stock rail is on a ...

... topic: 1919 Three Way Tandem Point posted: 10 Apr 2012 19:50 from: Les Waters I have been using Templot for off and on for several years as and when the need arose. I have just started on planning for my new layout which is prototypical. I have had the track plan scanned and I am using this as a background shape. All has gone very well using TDV except for a three way tandem point- the very last piece of the jigsaw. The problem is my lack of knowledge and terminology. When I try to follow the excellent Templot video I can sort of understand it until my lack of knowledge takes over. Specifically, I do not know if what I am trying to do is allowed bearing in mind the background shape of the prototype requires two staggered B8 LH switches. These appear to be the best fit. Would this be allowed? The other area where I am failing is the third crossing and blades which from the video seem to be a user choice and I have not got a clue ...
95. tandem turnout
... topic: 2606 tandem turnout posted: 31 Dec 2014 16:29 from: Simon Dobson I have created the tandem in the attached box file. I'm quite pleased with it, but before I go and build it, would anyone please advise if there are any apparent "oops" in there? I do know that there is a slight overlap of wing rail and V in the centre, it is so slight that I did not see any reason to create another partial template to resolve it. I think the timbering is reasonable, but there is a significant angle on timber CR214X4-A relative to theFP and Blunt nose marks on the plan- nose of the middle crossing. To ensure that the chair would fit, should I use a bigger timber, or shove it backwards or...? intended region/ period is GW/ 1930 or thereabouts. The smaller radius leads off to the coal stage ramp, the larger to the rest of the shed. Comments very welcome!

... topic: 1176 interlaced sleepers on a 3-way turnout posted: 24 Jul 2010 11:40 from: Mike Waldron Has anyone produced a 3 way turnout with interlaced sleepers? Apparently they were fashionable in the early days of the LB&SCR. Would value any help possible Mike Last edited on 24 Jul 2010 11:53 by Mike Waldron posted: 26 Jul 2010 10:23 from: Mike Waldron I have just been running the 3 way Tandem turnout video- which is great- but I have not quite worked out how to get to the starting point- namely to being with both turnouts stripped of their central timbers. Added to which, I am working with interlaced sleepers instead of some of the timbers- LBSCR pre 1900 practise. I suspect that the timbers left out are the ones I will be interlacing- from the rear of the switches to the 4 timbers that the crossing and check rails are set on. It's just getting to that stage I'm not sure of. The rest I can work out from the video. ...
97. Dud(ley) Plot?
... the checkrails shortening by one sleeper to clear a point blade. The 2 slips and the 3-way interlaced turnout also require detailed work to add all the check rails etc- but I prefer to try this once the basics are OK. Any advice and comment would be appreciated. Richard Attachment: attach_1857_2466_Dudley1.box 298 posted: 6 Jun 2014 22:29 from: Ariels Girdle Practice makes perfect- or at least a little better! Here is a mark 2 version. The slip and the outside slip are unchanged, but the tandem 3-way turnout has been altered, as has most of the RH end of the plan. By pushing a couple of turnouts further to the right, I have managed to move some of the other pointwork a lot closer to where it ought to be- having struggled immensely with the tightness of it all at my first attempt. I doubt if I can improve the positioning and alignment much more- though there is still much else to do. Everything is still very rough and ready- particularly the timbering. I ...
... quite interesting track wise. There was a wonderful mixture of Flatbottom rail and BH rail at this location. It seems as though during the period that renewals were taking place, but due to the line being freight only until 1988, renewals seemed to have been quite selective. Funnily the Up main which for the most part was FB rail on a mixture of concrete and wooden sleepers still has semaphore signals, and the Down main for the majority is BH rail and has modern colour aspect signaling. The interesting bits are, the tandem that forms the loop and entry in to both sidings. The tandem is linked to the main via a single slip. In this photo its all BH which is dated as 86: http://railonline.zenfolio.com/p426225132/h353FB9B3#h353fb9b3 However not too much longer things start to change: Although these are much later photos, (used to highlight the track) I believe that the renewals began in 87 although I could be wrong but not by much. The tandem, which is a mixture of FB and BH ...
... topic: 1373 Constrained Tandem posted: 19 Feb 2011 09:31 from: JFS Dear All, My latest Magnum Opus requires a tandem turnout in a very tight spot. The closest prototype formation that I know of (although opposite hand) was at the Railway Megalopolis that was Brighton Kemp Town- fortunately on the same company as my fictitious example. http://www.semgonline.com/location/pics/im_kemptn-8.jpg The consequences are that the two common crossings are very close together and that the switch rails have to be very short with a continuous lump check. 1129_181823_010000000.png Although real railways would obviously avoid such formations where they could- the construction would be very much a "special" (the Kemp Town example is all block chairs)- there must have been plenty of other examples, perhaps especially in pre-grouping days and where operations were complex or space was tight. Fenchurch St and Charing Cross perhaps being examples. My question is: can anyone either upload or provide links to further pics or drawings of this or other examples as ...

For that second template in the tandem you had the TS side ballast+ cess option on. But for some reason with the trackbed half-widths (ballast edges) set to only 20mm. The default half-width is 7ft-6in= 52.5mm in 7mm scale. For a total trackbed width of 15ft (105mm). Here is your box file with that trackbed turned off. However, because you were in the middle of the tools> make tandem function, it probably won't be able to finish it ...
