... Brook Smith P4 gauges? Iv'e uploaded 2140_091045_590000000.jpg pics so140_091048_450000000.jpg you can see where I am at the moment. Regards Len Cattley posted: 9 Aug 2009 18:33 from: Paul Boyd Hi Len Conventional wisdom is to start from the straight stock rail, but in this case I might be tempted to work outwards from the centre. I mainly use three-point gauges, but do also use roller gauges on straight track. Also, a check rail gauge is essential- check rails are gauged from the crossing, not the adjacent stock rail. As an aside, is the Templot plan going to form part of your track base? The reason for asking is that you'll never get the formation off that double-sided tape!

... anyone tell me how common was the use of these chairs (S1J joint rail chairs) on the railways please posted: 24 Sep 2019 19:18 from: Rob Manchester John, My understanding is that S1J chairs were used on 12" joint timbers at the ends of each track panel. The S1J is 10" wide rather than the 8" of the standard S1. Rob posted: 24 Sep 2019 20:25 from: Martin Wynne Hi John, The use of the heavier joint chairs on wider 12" sleepers adjacent to the rail joints at each end of a track panel was common practice in the pre-group period (pre 1921). They were often used in conjunction with shorter 9" 2-hole fishplates so that the joint sleepers could be very close together, typically at 15" centres with only a 3" gap between them. The theory being that strength in the rail support was more important than strength in the fishplate. Generally the theory fell out of favour in the light of experience. Here's a list of ...
... Screen shot with check rail ends machined. 2151_050741_050000000.png The later would be more appropriate to your era. Regarding the track spacings of quadruple tracks, there are two main ways of doing this. The WCML was generally arranged as Up Down fast, Up Down slow and would be spaced at 11'2" 15' 2" 11' 2" centres. The alternate way as exemplified by the ECML used Up slow Up fast Down fast Down slow spaced at 15'2" 11'2" 15'2" centres. These can be set under GEOMETRY, ADJACENT TRACK CENTRES.

... fairly agricultural device? 2854_111445_530000000.jpg Best wishes Eric posted: 11 Jul 2017 23:03 from: Nigel Brown In this context, what are the switch rails? Knowing nothing about stub points, think I'd assume that the pair of rails which move are the switch rails, whereas from your question I get the impression that you're using the term for the 3 pairs of converging rails in the pic. If that's the case, then (again, I know nowt about this) I suspect that what is essential is that the rails adjacent to a particular pair of rails don't act like check rails. So the gap needs to be larger than the check rail gap. For a gauge G, BtB B, flange thickness F, then: gap> G- (B+ F) Think that's right. Don't count on it. Nigel posted: 11 Jul 2017 23:33 from: Eric Gates Nigel Thank you. You are right: I am struggling with the terminology. I need to understand the appropriate gap between the rails on which the different ...

The things that look like odd shsped check rail in both roads in the middle distance -- what are they? What is the thing adjacent to the left hand switch rail in the foreground? Are these overhead lights in the middle distance? I note there is neither third rail or OHLE. I am sure there are many on this forum much more knowledgeable than I.

... Julian Roberts Hello Making a track plan on a map, I have an irregular diamond slip where at one end the crossing is 1:7 and at the other it is 1:9. I am muddled up about which way round the slip road goes. I think I've followed the instructions, I have copied each half diamond and made them into turnouts without sleepering, and done the other tasks to make them into slip roads. Logically that would imply to me that the switch for the 1:9 crossing goes actually adjacent to the 1:7 crossing- is that correct? And vice versa, the switch for the 1:7 crossing goes adjacent to the 1:9 crossing. Or is it the other way round? I have printed out the template and it looks perfectly OK to me, but it may not be correct, I've ended up putting the shorter switch by the 1:7 crossing.

... Smith's GWR track book. Photo also shows the interwoven timbering and a skewed long timber on the turnout exit. Also modern Pandrol clips on the siding, but older spike fixings still on the running line cheers, Martin. Martin, every day is a school day. I was only at castle cary last weekend and didn't notice this catch in that detail. Prob cos its now very overgrown.I wonder why this type of catch was used in these positions. prob to make sure the trapped vehicle is well and truly clear of the adjacent running line.

... Hi Richie, I'm assuming you'll be using live frogs. Switching power to them will be quite an exercise. If you are using DCC you might be able to use "frog juicers". Regards, Andrew posted: 21 Oct 2017 22:57 from: FraserSmith All this talk about bundles of cables and techy solutions to crossing switching. You need to join MERG (merg.org.uk) and get into CBUS and probably cut your wiring by 80% or so. With the crossings there are several servo drivers that can be located adjacent to the point and also switch a relay to change polarity so avoiding problems of interference. The system can be used equally well with DC and and DCC. It's not that complicated and the help available to members via their forum is as good as here system Templot. Worth a look.

Not everyone understands or is good at maths. All I remember is SOHCAHTOA, but can't remember what to do with it! Paul Hi Paul. Well perhaps you shouldn't. I had to look that mnemonic up as it is a new one on me. Sine= Opposite/ Hypotenuse, Cosine= Adjacent/ Hypotenuse, Tangent= Opposite/ Hypotenuse. Trigonometry functions. Of all the maths I was taught at school Trig and Geometry are the things I still use most. It is quite impressive what can be achieved with it after all large parts of the world were mapped pretty accurately using triangulation. Much else I was taught has long since been forgotten. Another mnemonic is GIGO Garbage in= Garbage out. I am old enough to have used log tables and slide rules and they teach you to have a rough idea of ...

Does this look anything like your models? 2_021113_230000000.png A Templot .box file containing these templates is attached below. You can use them as a basis to start creating your own templates. I'm not sure what you mean by minimum track spacing? This depends on the width of the rolling-stock which you are running.

... system was to be modelled would help them get an answer. Hello, I am modelling the area around Bankhall Engine Shed, Kirkdale Carriage Sidings and Kirkdale Station. The photograph I attached to the original posting was in fact taken from the road bridge (Stanley Road) and is of the tracks leading past the Engine Shed and carriage Sidings from that bridge to Kirkdale Station. In the meantime, a contact who works at Kineton has measured the surviving Class 502 unit and I now know that the distance from the inside of the adjacent running rail to the centre of the third rail was 16.5", i.e. the BR standard for third rail electrics. What is (apparently) clear again from the photograph previously shown is that the system used standard 8' 6" sleepers but offset to allow adequate land to mount the 3rd rail. The missing piece of information that I now seek is what happened at the overlap where the conductor rail swapped from one side to the other for various reasons, e.g. pointwork or to move the conductor rail away from ...
... . (Apologies, I have just realised there is a small error on the above plans, the red line linking the lower level to the upper level has stopped short. They should be joined). The problem I am facing is that the length of the platforms is being compromised by the complex approach pointwork which at present is all standard straight points and double slips. Martin has suggested this could be much improved by customising the pointwork and building new curved points to move the entry further back, even moving it onto the adjacent board through 90 degrees. The problem I have is that I'm still really learning Templot and this is really throwing me in the deep end! Martin has very kindly drafted the basic plan but has suggested I place the plans on the Templot forum to see if you fancy a challenge! Of course if you really feel brave, any main line terminus design would be seriously considered. It should have 5 platforms of at least 8' length, parcels area, limited goods facilities and a comprehensive loco shed area for both steam ...

If I now use "wipe to the control" to make the branch track the control template, then tools| make double track TS the new track is spaced 25mm from the existing, and not 23mm as required.

From the top: 1st track is the spur on a rising gradient to eventually go to an MPD.(Obviously not at all prototypical) 2nd track is the main Eastbound track for expresses with 2 bays in the adjacent island platform( not shown) which in the original served Leeds and Wakefield. The through track below this is bi directional for stopping services. The loop below this no longer exists though I do believe that originally there were 2 tracks between the platform lines. I vaguely remember in my childhood, DMUs and the odd parcel van being left on this line(s). Presumably in my steam era, the station pilot would often be found lurking here. The through line below this is for Westbound express workings. The ...
... 16 Feb 2012 14:15 from: John Clutterbuck Dear Martin, Please can you add O14 as an official gauge in TDV as it is being increasingly used by several Templot users as evidenced by previous discussions on this group. Based on the published standards (available at O14 Group Standards) my suggested settings are as follows: 7.00 mm SCALE per ft.( RATIO 1:43.54) 14.00 mm GAUGE between running rails. 1.00 mm flangeway gap. 2.00 mm flangeway end gap (check rail flared ends). 70.00 mm adjacent track centres, turnout side. 70.00 mm adjacent track centres, main side. 600.00 mm minimum radius limit for warnings. Please let me know if you need any further details? Finally please note we agreed in 2008 that the official designation is O14 (i.e. Capital Letter O followed by 14) and not o14 or O-14 as often used.

... very happy that it worked) but I am having a few troubles in trying to replicate NSW Government Railway point characteristics, particularly sleeper layout. My dramas so far: 1. My single slip L/H point blades do not flow into the stock rail properly. My R/H points blades are fine. Realistically it wont affect building the slip but I would like to know where I went wrong; 2. My track plan includes a passenger siding bay within one of the platforms. I specified a track spacing between adjacent track of 85mm however Templot has drawn it at 71mm and I can not adjust further; 3. I am after a plain track and point sleeper spacing of 600-628mm between centres (prototype). When I go to 'real' and then adjust point timbering it seems to only adjust the middle set of sleepers. I do not know how to adjust the plain track sleeper spacing. It seems there are only pre-set values i.e. 60ft rail/25ft sleeper spacing options. I have tried the customised spacing ...
... the only difference, that I can see, between my attempts and your video is that your video is mandraulically constructed whereas the crossover in my attempts was auto-constructed as a ladder crossover- resulting in a 1:12 slip. TIA& best rgds, Dave Pundefined Attachment: attach_1647_2221_Newcastle_NSR.box 262 posted: 9 Aug 2013 11:23 from: Martin Wynne Hi Dave, Thanks for posting your file. A few pointers: 1. The Down Loop is too close to the running lines. Where a loop or siding is adjacent to a running line, the rules require the track spacing to be increased by 4ft to 10ft way instead of 6ft way. In 2mm scale you need to increase the spacing by 8mm for 4ft scale. You can do that by mental arithmetic, or simply by entering #8 in the data-entry dialog. Here's a bit of Jing video showing that (in 4mm scale): http://screencast.com/t /u98lh6UQzbQ It may take a few seconds to download before it will play. 2. You ...
