... Hamilton posted: 23 Jun 2008 11:29 from: Paul Hamilton By the way, this plan is to be resized from 12' x 10' as shown down to 11'6" x 9'. As such I will relocate the upper station as shown as the high level track at the bottom of the layout. This will be moved 12" down to sit right on top of the lower tracks. This will compensate for the loss of 12" in the layout in a North/ South direction and thus maintain original gradients. The 6" loss over 12' I don't see as a big deal at all and it should have little impact on the overall project. Also I am compressing things slightly in terms of width of the alyout around the room, limiting my design to 24" maximum as seen in the East and West sections of the layout. This impacts on the sidings where the goods shed is shon in the North but little overall impact. The South area as mentioned will now be only 12" wide as the station will ...
... the curves are still too tight and the track spacing is too large. The file 'Layout templates 19 Feb.bgs' in the file; http://perso.orange.fr/brian.tuckey/Templot files.zip is therefore only a guide. At the bottom of the diagram you can see the junction layout that precipitated this thread and I overlaid track as can be seen from the file; 'New Layout_07_07_09_0155_32.box'. However, after my initial posting I calculated that the space between the junction and where the terminal track passes over the mainline would produce an unacceptable gradient. I model in P4 so no traction tyres! I therefore produced a second design as can be seen in 'New Layout rev2_07_07_09_1753_51.box'. I believe that this is more accommodating and provides the height/gradient profile required. I am modelling OHLE so a larger than normal height clearance is necessary. To the left of the junction you can see the return curve which was the topic of an earlier question. Thanks for your help and all suggestions/criticisms are welcome.

... not, there are other interesting possibilities. The existing bi-directional roads could be ramped up from each end and swing round to access a new bi-directional high-level fiddle yard across the middle of the layout area. Using the existing bi-directional connections would involve some operational conflicts over the single-track ramped sections, but remain entirely clear of the existing up and down yards access. I think you can get about 5 metres of ramp to say 75mm clearance, which means 1:65 as a ruling gradient. Would that be ok for your motive power? As the ramps are out of view, you might experiment with running a lathe knurling tool along the rail tops to increase adhesion. It's all a lot of carpentry, but you could have say 18 new fiddle yard roads with the operational flexibility of all of them being bi-directional. The downside might be taking two of the existing three bi-directional roads out of use while you build the ramps. regards, Martin. posted: 17 Nov 2007 18: ...
... 16.5mm (which is for EMGS wheels). cheers, Martin. Hello Martin, Thanks for the tip on the phone. I'll try it out and let you know. As to the wheels they are Alan Gibson wheels that I have largely standardised on and the loco is one of his as well. A very nice kit with a mixture of white metal, nickel silver and brass which as a layout loco is good for me particularly on my old layout of Maiden Newton/ Yeovil in 00 there were sharp curves and steep gradients and the weight of the white metal really helped the loco's pulling power. I've got three of them, one open cab as on the video, a closed backed cab, both of which are panniers(based in Yeovil in the early 20's and a third, yet to be built, in saddle tank format...gorgeous. So coming back to your thought on back to back I take it that 16.5 is correct for Gibson and the odd Ultrascale wheel? Kind regards Andrew Last edited on 20 Oct 2018 20:56 ...

The safe minimum clearance for 00 stock is probably around 60mm and I note you had a run of 90" which equates to 2286mm. This is going to give a gradient of 1:38, not impossible but a little on the tight side. Really depends on what stock you are going to run. Diesel locos are generally much better with more weight and all wheel drives. I'm guessing but steam locos may be pushed with more than 4 coaches. At ...
6. Elevation
... topic: 3238 Elevation posted: 10 Mar 2018 22:40 from: dave turner Hi Martin, Before you scream, or throw your hands up in horror, about the subject please bear with me. One of the interesting things about XTraCad is that it appeared to allow for different levels in a model railway, particularly including vertical transitions. -Note that I'm not talking about the extreme gradients that Hornby Dublo, amongst others offered. My basic question is:- If Templot is used to create plans for a multi-level network how much 'fettling' would be required? For example I've observed that many large models use spirals to transition from one level to another. At sensible gradients could native Templot allow for a change in gradient? My suspicion is not, but how far out would one practically be? (Piece of string)? regards Dave posted: 11 Mar 2018 13:12 from: Martin Wynne Hi Dave, Templot is neither 2D nor 3D. It is referenced to the rail top, so that the printed output can ...
... way, over what length should I transition from level to about 1 in 30. Any thoughts from the wise? Thanks, Pete posted: 14 Mar 2014 13:16 from: Martin Wynne Pete Brownlow wrote: Or to put it another way, over what length should I transition from level to about 1 in 30. Hi Pete, Are you sure about the 1:30? That's very steep, especially if on a curve. Have you checked that your locomotives will pull a train up 1:30? Model gradients are usually around 1:60 to 1:80 for running lines. The short answer to your question is about 250mm- 10" or roughly the length of a coach as the minimum length for a vertical curve. Here is a diagram from Russ Elliott (with the gradient much exaggerated): vertical-curve.gif Obviously if you have room for a longer vertical curve, so much the better. Especially if you stick with 1:30 gradient. There was much discussion about vertical curves on E4um and the Templot email ...
... topic: 2595 Indicate gradients and elevations posted: 11 Dec 2014 17:42 from: Godfrey Earnshaw Martin, Templot software knows exactly where each point is, in particular, the peg positions. How difficult would it be give each each template a starting elevation and a gradient and let Templot calculate and display the elevation at other peg positions, notably where they connect to the next template. This would then set the start elevation for the next template and the gradient could be changed, etcetera.... This would enable users to have instant access to elevations, slopes and clearances. To me this seems like an easy task. However, I'm not the one who will have to code it. Ignore the last Sentence, it's just barefaced cheek. Cheers Godders posted: 11 Dec 2014 18:36 from: Martin Wynne Hi Godders, I've looked at this a few times. But what seems to be simple is in fact a minefield. I set out originally to create a 2-D track plan referenced to the rail top. ...
... available of 18' square. The room is the converted loft space above a double garage and has been fully fitted out with a proper staircase, heating and lighting to eventually house a multi layer 00 layout. The lower level is under construction now and will have 12 through storage roads, each about 30' long. The lower level will be about 18" below the scenic level which will allow full access to the storage roads for track cleaning and point repair etc. Joining the two levels will be a spiral at a gradient of 1:100 which takes three complete circuits of the room before emerging at the upper level. The scenic side will be mainly urban with brick cuttings and retaining walls. Period will be late '60's, ECML in the transition from steam to diesel.

It is now part of Tramlink and still has interlaced track. 090-090 Norwood Fork Junction. Note the OHL for the LBSCR type electric trains. All fascinating! John posted: 28 Feb 2010 10:43 from: Paul Boyd I'm puzzled by this one: 085-085 Trap Points on Interlaced Track, Single Line If this is on a gradient, surely runaways need to be protected in both direction- why not put the trap point after the interlaced tracks merge into single line?

... have been sent hurtling towards the end of the platform. For this reason I think it is most probable that there never was one. Scott posted: 23 Jul 2018 22:30 from: Richard_Jones I think I did my catchpoints by just taking the "switch bit" from a turnout and blanking the rest out- here's a picture of the finished product.... I trimmed them back looking at photos of the prototype- one of them was a weighted points to protect against wrong line run away on a falling gradient- I presume the lever would have "bounced" every time an axle went through it in the normal direction? cheers Richard 1763_231727_350000000.jpg posted: 25 Jul 2018 21:41 from: ScottW Thanks, Richard for sharing your photograph.

... this is a running in both directions trackwork scenario. I understand that the keys near joins should be chaired away from the joint but can't discern which was the rest of the chairs should go. posted: 27 Jun 2010 11:09 from: JFS As a general rule, the keys point to resist the traction forces so that the rail creep would tend to tighten the chairs up- that is the keys point against the direction of travel where trains brake and with the direction of travel where trains accelerate. Where there are gradients, the keys point up-hill. But these are only general rules- in practice, if the gangers found that the keys fell out, then they would reverse them: in difficult situations they might key alternate chairs to oppose each other. You are right about keys at rail joints- this allows the sleepers to be spaced as close as possible. Hope that helps.

... : Phil O Hi, the first thing that jumps out at me, is that you have to access a siding before you can use the head shunt to access the rest of the yard and it also ties up a platform whilst you do it.

... the south of the station where two separate lines appear to leave the station and split apart, but eventually come back together again to form, one track. At first I thought it might have been for some flying junction arrangement but Google Earth doesn't show any old earthworks which might justify this. Jim. posted: 25 Apr 2011 21:15 from: Rob Manchester Hello, According to the ever useful Wikipedia :- 'The single track line between High Wycombe and Princes Risborough was upgraded to a double track. Because of the gradient the new Up line followed a different route (with a short tunnel at Saunderton) from the existing single track, which became the Down line (with a few changes because of the gradient or for other reasons). The Great Central built a new line from Marylebone to join this railway at South Ruislip (then called Northolt Junction)' It seems odd that a small offset in the route would have a gradient sufficiently different to make it worth it. You can see the alignment on the OS map at multimap. ...
16. Cockett Station
... topic: 2212 Cockett Station posted: 7 May 2013 21:18 from: MarkAustin If you look at the track diagram of Cockett Station Goods yard, you will see two trap or catch points just after the first turnout in the yard. To put the layout into context there is a 1:200 rising gradient over virtually the whole length of the branch from the station to the yard. My original thoughts were that the trap points were to protect the turnout and therefore slaved to it's lever, but later thoughts incline to thinking they are to prevent runaways down the gradient, and would therefore have their own lever. Any thoughts?1911_071617_150000000.png posted: 8 May 2013 06:58 from: JFS Have you got the signal box diagram?

... I am heading into retirement, I am looking to creating a fairly major layout based in the North of England in the late 1950s, modelled in OO-SF. The aim is to have a major station down one side of the room, long enough for full length train formations and a multitrack fiddle yard on the other long wall of the room creating a large 'roundy roundy'. Eventually the short wall opposite to the door will hopefully become a fair sized MPD with the main running tracks under, accessed by a rising gradient behind the station. My plan is to learn to hand build the turnouts on the station board and use peco for the fiddle yard. I am starting track planning now so I can spend the next few months learning to build trackwork and then when the trackplan is completed hopefully produce some turnouts to put in store for the actual build. For the plain track; I am currently leaning towards DCC Concepts 'Legacy' flexi-track. I have spent much of Christmas on the steep learning curve for Templot and have created my ...
... end of the key remains protruding from the chair pointing in the opposite direction. The reason the rails move in the direction of travel is because of the way the rails flex under load and get pushed forward by the wheels. It is similar to what happens when rolling pastry -- the whole mass moves forward on the board in the direction in which it is being rolled. However, there are sometimes situations where rails are found to move backwards -- for example on the inside rail of sharp curves and on steep rising gradients. If a situation is found where the keys frequently work loose, some or all of them will be turned round and driven in the opposite direction. On single lines or where traffic is bi-directional, the usual rule of thumb is to drive the keys "towards the joint, towards the station, towards the river". That means on level track between stations the keys are driven into the chairs towards the nearer of the two rail joints in each rail length. Approaching a station, where trains are braking ...
19. "Plan Y"
... sets/72157626467480449/ posted: 24 Dec 2011 19:14 from: Ian Allen Well after the work of April, there have been some changes made to the plan of how it will be constructed. The two lines with no timbering shown are now going to be "tunnelled" as cut and cover, rather than on a viaduct as intended which means the junction to the left of Coulsdon has changed too. The approach to the goods yard has also been altered. One advantage of the tunnel option is that the steepest gradient is relieved from a 1 in 72 to a 1 in 86. Once again, still more work to complete re-timber shoving etc. Attachment: attach_1283_1429_PLAN_Y_TUNNEL_VER SION.box 387 Last edited on 26 Dec 2011 00:31 by Ian Allen posted: 31 Mar 2012 19:30 from: Ian Allen Just returned home after our group AGM.

... , Martin. posted: 14 Apr 2015 12:49 from: JFS Sounds like a very useful feature- many thanks Martin. Best wishes, Howard posted: 23 Apr 2015 09:20 from: Andrew Duncan Hello Martin Yes I agree with Howard that will be very useful and will certainly add clarity. So thank you for this a nice touch. On the subject of adding stuff to aid clarity, is it possible to add notes that show on the Trackpad. For example things like Datum (+ or -), Gradients, Up and Down lines, etc? In the end I suppose I'd like to be be able to annotate the plan with all the usuall infrastructure from buildings, to embankments, bridges, rivers, fences/hedges, trees etc et. I have recently started to use the Sketchboard to add a bit more character and scale to the plan, but it doesn't really answer all my needs in that area. I appreciate that Templot wasn't designed for this perhaps and certainty this comes under the category of 'nice to have' ...
