... .... is it possible to export to PDF with the background shape included? I'm running templot on WinXP via VirtualBox on Mac OSX10.7 and using an Epson 1290, and while any other Win application can see and communicate with the printer, templot does not though it seems to send somewhere. I'm quite happy exporting to pdf which is printing fine (stable dimensionaly) from preview or Photoshop CS5 but would quite like to be able to include the background so i can visualize what I have to deal with in terms of gradients, structures, S&T installations and perspective. At this stage I'm working over a rescaled and cleaned up engineers 1:500 OS sheet(rescaled to match P4 at print size) and the next stage is to see where i can trim a little length out before sorting baseboard shapes and sizes before sending the whole lot as a pdf to a plotter. Thanks in advance for any help or suggestions Steve posted: 28 Feb 2012 09:41 from: Martin Wynne ESJAYTEE wrote: Returning to this theme.. ...
... need to be silly CF18 to be anywhere near a suitable radius. The outside of the outer loop wouldn't be a problem. As I touched upon earlier I have a version of the plan where the exit road from the steel terminal does not join the mainline curves, instead would feed along side the mainline in to the fiddle yard, the idea being that I could get in a slightly longer seperate fiddle yard road for it and be able to have that fiddle yard road a little lower than the mainline to help with the gradient (for info stands about 1:80, possibly with lifting the mainline slightly as high as 1:100).

... it has been found more suitable to maintain the lead length constant along the centre-line of the main road. This minimizes distortion of the switch area, at the expense of some slight distortion to the V-crossing. Generally modellers experience greater difficulty with curved switches than curved crossings, so that is a trade-off worth making. Curving on the main road centre-line also permits turnouts to be aligned onto clothoid transition curves and slewed tracks. That's not something the prototype does (because there would be a cant gradient through the switch), but it's extremely convenient for modellers working within a cramped space and with very sharp radii to be able to roam a turnout into a transition zone. Templot uses the clothoid form for transitions and a modified hyperbolic tangent function for slewing. The Bloss transition is not supported. Professional p.w. design software creates curved turnouts from first principles without a pre-defined lead length. I have software code here which can do that, but it is not part of the Templot product. Templot is designed and ...
... stop? It's currently 4000mm long for the area shown (13ft x 9ft ish) in EM. End curves are around 4ft radius. I set 8ft way for the running lines (rather more than is necessary, but that's what matches the drawing), and 13ft way for the carriage sidings. I don't know what's intended for the other side, I inserted a simple link. There isn't room for a fiddle yard. Perhaps these tracks drop down to a folded-8 design with storage under the station area? The gradients will be a bit severe in only 13ft x 9ft. For working over a scan I find it easier on the eyes to use a negative image with reduced contrast, and the "bright night" colour scheme. Here is the plan like that for you if you want it: mrn_plan_grey.jpg Right-click on it, and select Copy or Copy Image. Then in Windows Paint, do Edit> Paste.

45. Penrhos Critique
... proposed layout Penrhos. It is to be a model of the real place (just west of Caerphilly) set in 1920. There are four lines operated by three companies. A composite scan of the local maps is attached. The intention is to model the whole area of the map westwards of the road bridge. The ANDR operated the E-W double track from Penrhos junction to the footbridge and it is almost level. The RR operated a parallel double track that becomes a single line. This line is on a falling gradient of about 1:80 from the viaduct becoming 1:40 further west. The Barry operated the other two lines from the junction with the Rhymney and the line over the viaduct. The viaduct line falls at about 1:80 to meet the exit from the exchange sidings. Attachment: attach_370_598_Penrhos2.jpg 637 posted: 27 Oct 2008 00:56 from: Richard Spratt The scale is P4 and the minimum radius is 36", although some templates still say 1000mm. The intention is that on the scenic side there is no ...
... ..and so on. KISS principle applies at all times. Let guys play around just joining bits of track on screen before they even start to think about all the degree stuff. Have fun and enjoy it at the front end. Go back to your schooldays and recall all those layouts you spent hours scribbling on the back of your school exercise books. Those are times when your imagination knew no bounds. Needless to say, none of them ever got built or even assuming you had the funds, they couldn't work as the gradients were far too steep and 4mm loco's won't go round 12" radius curves.... Of course you have to cater for the finescale modellers, but not everyone who builds their own track is that camp. Give everyone the basics and let them go from there. I felt I was totally overloaded from the beginning with so much data. You were giving me everything, whereas all I wanted to do was just join two pieces of track together.... Once guys master the basics, everything else will ...
... it along the turnout road centre-line (or along the rails) using the CTRL+ F8 mouse action. The parallel type of V-crossing is something of an oddity and not often used. If I was starting Templot again I would probably not include it. But I can't now remove it without breaking existing .box files. It is useful if you want a return curve within a transition zone: 2_010718_160000000.png (The prototype doesn't* put pointwork on a transition curve -- because of the impossibility of running a cant gradient through a moving switch -- but it's a handy device when fitting model track in a tight space.) Adjusting the turnout road length with CTRL+ F12 is intended to deal with short** gaps and overlaps after other templates have been aligned, and for use with partial templates. It's not intended to create a significant section of track -- for that you would use the tools> make branch track function to create a separate template (which might be quite short). *never say never. It would ...
... , rotate, combine, items. It's tedious to add fine detail using this method, but very easy to change colours, line thicknesses, etc. Such drawings are vector graphics, so they don't break up as you zoom in on them. Such drawn items can be shared as .sk9 files. 2. You can add a bitmap image created elsewhere in a full drawing package such as DrawPlus or CorelDraw. The Goods Shed in this view was added that way. This way makes it easier to create fine detail, add gradient fills, textures, shadows and similar effects. Once added to the sketchboard such an image can be stretched and rotated, made transparent, etc., but there are no controls to change the colours or details. Depending on the size of the original image, it may break up as you zoom in over it. Such drawings can be shared as normal image files, usually in .gif format for ease of making the background transparent. 2_301156_270000000.png There is then an option to have the sketchboard items displayed back on the workpad ...

... Jan 2012 09:35 from: LSWRArt Hi Tony What is the difference between a catch point and a trap point in appearance? According to Wikipedia a trap point can be single or double blade and the inner blade can either be contained within the running rail, or cross over as a full point into a sand drag or buffer stop. So the first two of these seem to overlap a catch point in appearance (although again, according to Wikipedia, a catch point is only used to catch stock running away on a gradient and all points protecting a main line from a siding should correctly be called trap points). Would a single blade trap be sufficient to protect this works siding, or what would you suggest is correct prototype practice (circa 1912) Thanks Arthur Arthur posted: 27 Jan 2012 10:01 from: Martin Wynne LSWRArt wrote: What is the difference between a catch point and a trap point in appearance?

... dummy vehicle function below. regards, Martin. posted: 19 Feb 2012 12:24 from: Ian Allen Hi, taking your original question, I have purposely set the track centres on a new plan at 90mm in O gauge because of the issues you have highlighted. IIRC the Gauge O Guild standard is 82mm, so I have allowed for any clearance issues. There is one section though where the track centres have been moved out to 100mm for additional clearance due to the curvature(6' 1" minimum)and gradient profile. Using Martin's formula, and hoping my calculator and I worked this out correctly, track centre increase should be just over 2mm for a scale 6' radius curve. However on the current SR7mm layout there is one section where the track centres are 85mm and BR MkI coaches have been known to "catch" each other when passing. This will be rectified in due course.

... it will be RAM, and if you wanted that to be CLM, you have to click the menu item again. The V-crossing angle is displayed in both RAM and CLM in the info. *displayed to two decimal places. The internal angle will be an exact conversion. if you want to enter the angle in decimal degrees instead of unit angles, prefix it with a letter k. So entering k5.75 sets the angle to 5.75 degrees (5o45'). if you want to enter the angle in% gradient instead of unit angles, prefix it with a letter g. So entering g25 sets the angle to 25% (1 :4 RAM). There are several more of these input-conversion code letters. For example prefix letter i lets you enter inches when Templot is asking for mm. So i10 sets a dimension to 254mm (10"). Follow the help links on the data-entry dialog for more about input conversion factors. You can also define your own custom factors. p.s. I have today ...
... GWR way of doing things Hi David, I did say "generally". It's interesting to refer to the PWI handbooks "British Railway Track". BRT3 (1964 edition) refers to the physical object as "catch points" and "catch roads" throughout. See p.154. So clearly it was not only GWR practice at that date. In BRT4 (1971 edition) all such references have been changed to "trap points" and "trap roads". See p. 150. The sprung trailing catch points on gradients are now called "runaway catch points". So both are right. But for most of the bullhead era popular with modellers they seem to have been called catch points. Except where they weren't. regards, Martin. posted: 17 Aug 2013 21:50 from: Les G DM wrote:...This may be yet another example of where something is called one thing on one area and something else on another.

... 11 May 2014 22:22 from: Martin Wynne On RMweb Michael Woolford asked about inserting a double-slip in a transition curve, see: http://www.rmweb.co.uk/community/index.php?/topic/67805-converting-to-em-and-handbuilt-track/page-5 #entry1447437 I thought my reply might interest members here: Hi Michael, A slip in a mathematical transition? No, or at least not in traditional chaired track. Transition curves are normally used where there is a cant gradient (increasing superelevation) which means in effect that there is a twist in the track. Switch rails inserted in a twist wouldn't be able to slide properly or align with the stock rail. There is no major reason not to insert a slip as a special one-off in a flat transition curve, but I'm not aware of any. What is much more common is for an effective transition to be created by using a different fixed radius between each crossing in a diamond. This is often the case for a double ...
... , a much longer curve than I've made. However I've tested all my locos through the crossing again, at different driving wheel positions, and the only one that derails at one position of the wheels has a badly overgauge BB setting of around 17.85, something I've meant for several years to remedy. Unfortunately it's otherwise one of my best locos! Wagons go through perfectly, and I made a video of three of them propelling my Crab loco with the motor disconnected. With its tender it weighs a good 800g, and the gradient is slightly uphill towards each end of this test track http://youtu.be/ _O0pKy8c2oo Cheers Julian Last edited on 10 Dec 2020 09:54 by Julian Roberts posted: 10 Dec 2020 10:20 from: Paul Boyd Hi Martin Thanks for that diagram, that makes perfect sense now!
