... with an error condition. Instead I'm thinking of calling them "curviform" diamond-crossings. We can't simply call them "curved" because of course a regular diamond-crossing can be curved. Comments welcome: Make Ladder Crossover A ladder track is one which crosses running lines diagonally, comprised of a string of diamond-crossings and/or slips. In Templot a ladder is created by clicking the tools> make ladder crossover menu item repeatedly, once for each diamond-crossing. This makes it possible to change the adjacent track spacing for each diamond-crossing (geometry> adjacent track centres... menu item) as necessary. If slip roads are needed, they are added to the diamond-crossings afterwards. There are two types of ladder track: 1. In a regular ladder, the diagonal-road has the same radius as the main-road (or both are straight), and all crossing angles are therefore equal. Regular ladder tracks are comprised of regular diamond-crossings, and are commonly seen in station throats ...

... as well. Andrew posted: 14 Jul 2018 05:11 from: Andrew Duncan I can barely believe that its been 6 months since I've reported any progress on Pen Mill. I've not been totally idle, nor have I made great leaps forward. The catch point is in on the carriage siding. I've added all the feeds/ droppers in now, so the amount of wires underneath have burgeoned. I've almost got all microswitches switching the correct polarity. I've even got close to getting the diamond crossings being switched by their adjacent turnouts. It remains to be seen whether the micrswitches stay correctly aligned to give reliable switching over time. I maybe worrying unnecessarily but I'm beginning to wonder whether I'd have been better off either using either Megapoint electronic control( as I did on the junction baseboard)or frog juicers for this? Does anyone have any experience of the Gaugemaster frog juicer. I have bought a couple but not used them yet and since read that they will only take a couple of amps( my ZTC has a 5 amp output) power ...

... top of each other and gaps down to about 6" with bad language to suit, I have a very good vocabulary when I have had to pack timbers in confined spaces. HTH Phil posted: 29 Aug 2011 23:27 from: Brian Nicholls Hi Phil, Many thanks for the response to my query. You have certainly given me some excellent pointers to the gapping between the timbers which make perfect sense, bad language and all. My particular problems are mainly due to Vee& knuckle timbers (and K) of adjacent turnouts and diamond crossings being more or less in line with each other, making it very difficult to clear the directly adjacent timbers. The amount of twist required for the timbers not to overlap would be quite considerable and may not be achievable, it appears the solution would be to move one or both of the timbers either backwards or forwards to reduce the amount of twist to a more sensible amount. I think you may have given me a possible solution by increasing the width of these timbers, and then moving both timbers ...

... . You may need some trial and error on the turnout angle and position to get the desired result. If you attach your .box file instead of a screenshot, I can be more specific and try some sizes for you. regards, Martin.

I changed the turnout to a B-8 and moved it forward a little. I changed to a curviform V-crossing. I set the adjacent track centres to 28.12mm to match your plan. Then tools> make ladder crossover> make curviform ladder. Then tools> make branch track, and make transition to link back to the existing track. The result is an irregular diamond-crossing having angles 1:5.46, 1:4.5, 1:3.89 At 1:4.5 fixed K-crossings this will be far more reliable with the wide N-gauge flangeways than your original flatter diamond, which would have needed to be a switch-diamond (movable K ...

... topic: 2179 Making 6ft Way 7 ft posted: 16 Mar 2013 12:52 from: Ian T Hi, I've been trying to develop a fairly complex double track station with 5 platforms that involves several double slips and lots of crossovers. Reading several of your threads the 6ft way is only nominal so I felt that I would be safer clearance wise if I improved the track spacing to 50 mm. I then set up the {gauge/ Scale selector- custom-a} to basically EM dimensions except adjacent track centres of 50 mm and Min radius of 900 mm. When I start creating track I get EM dimensions. The Gauge/ Scale selector shows "50.00 mm Adjacent track centres, T S. (44.67 in use)". 1. Where did I go wrong? and secondly how should I calculate the correct spacer ring diameter to check my spacings? (Or better still where should I have gone to find out the information?)

... Oct 2017 10:04 from: Damien Morris 0eda7dda3d887297a0b1fb0a1ed4cfd0.p ng What is the best way to line up and bridge the 2 turnouts on 2 expanding parallel curves? Last bit needed before I have to go back over the layout and go through sleepers. Attachment: attach_2531_3107_conwy.zip 216 posted: 13 Oct 2017 11:50 from: John Palmer I would do it by making TL533 the control template, then making the crossover by using Tools -> make ordinary crossover. Before doing this, however, you need to adjust the turnout side adjacent track centre for TL533 so that the crossover thus formed aligns with the adjacent down main line (PR477). Because TL533 and PR477 aren't running parallel here, you will need to pick an arbitrary point on PR477 at which to measure its current offset from TL533 then make some adjustments after the crossover is created.2129_130634_140000000.png As the image shows, I picked a point on TL533 lying opposite the expected mid point of the crossover, slid the peg to this point with Ctrl-F8, placed the notch under the peg (backslash key ...

... ? The information I have is all from the 1930's. Hi Andy, See: http://www.scalefour.org/downloads/gwrtracknotes/R4290A.pdf That is Paddington's 1959 re-drawing of the Standard Railway Equipment (REA) chair designs and contains a few differences in the dimensioning compared with the original SRC designs. Not enough to make a a difference in a model. The GWR and BR(W) always had to be different. AS1 is an ordinary chair. AS1J is a joint chair used on 12" wide sleepers adjacent to rail joints. I can't find an online source of the original 1923 designs. They are in the NERA reprint book of the LNER 1926 SRC Permanent Way drawings. regards, Martin. posted: 22 Jan 2016 04:45 from: Andrew Barrowman Martin Wynne wrote: Andrew Barrowman wrote: Can you point me at a list of the various chair types?

I agree that there seem to have been substantial similarities in the practices of the Scottish companies and I counted myself very fortunate to have encountered a North British interlaced turnout as late as the 1980's. At the time I measured it, its through-timbered replacement was lying on the adjacent loading bank, so it was an opportunity not to be missed. Re-examination of photographs available to me revealed a Lens of Sutton shot taken in the late 30's of a Yorkie tank departing Helensburgh, with an interlaced tandem in the foreground. Unfortunately it lacks sufficient depth of field to make interpretation of the timbering easy, but it appears to have a mix of standard nine foot sleepers and longer, heavier crossing timbers. As best as I have been able to divine it from the photograph, I have reproduced this ...

... the Russ Elliott page gives this as 12 timber bays for Southern Electric. To achieve this overlap: 10. Select a length of plain track where the overlap is to occur and create the pair of conductor rails from that template as above- or- take an existing length of conductor rail where it will be swapped over and delete it to the control. 11. Click real- timbering- no timbers but do not omit either rail as before. Click Main- save and background. 12. Do the same for the adjacent length where the swapping will take place. You should now have two adjacent templates both with the two conductor rails showing. 13. Return to the first template now on the background and Main-delete to the control. You may find you have to extract this from the Main -Storage box rather than trying to click the conductor rail template on the trackpad. 14. With the peg at the opposite end of the template (Ctrl-0 or Ctrl-1) to where the overlap is to take place, ...

... topic: 2761 New mouse actions -- adjust adjacent track centres posted: 19 Oct 2015 21:07 from: Martin Wynne Most of the recent changes in Templot have been to assist beginners. So I thought it was time to do something for established users who know what they are doing. I have added new mouse actions to adjust the adjacent track centres settings, instead of entering the dimensions directly. This makes use of the geometry> centre-line options> functions in order to see what you are doing, which means these need to be reset afterwards. The new mouse actions will be useful in two situations: 1. where you have some existing double track at an unknown spacing, and wish to create some connecting double track into which you can insert a crossover, say. 2. when using the dummy vehicle tool to determine the required spacing for running clearance at different radii. I have made a quick bit of scruffy video illustrating that: http://flashbackconnect.com/Default.aspx?id=r6BdZWxz5kk5ye1ek-P -Ag2 ( ...
