I have jumped in at the deep end and maybe am being over ambitious, but you don't know until you try! Some questions:

Hi Chris, I believe that up to 1910 the Rhymney used flat bottom rail and I fancy trying to model this. Which data set in Templot comes closest to modelling 'old fashioned' point-work?Ideally you need a drawing or at least some dimensions of the Rhymney pointwork so that you can create matching custom templates in Templot. In the absence of that, most of the smaller pre-group companies used loose-heel straight switches. You can find a generic selection of those at the top of the list at real > switch settings... menu item. Click the ? help F1 button on that dialog for some detailed notes. You didn't say which model track gauge you will be using, but if is not P4, S7, etc., you can't model loose-heel switches exactly because there is not sufficient flangeway clearance at the heel. You can move the position of the loose heel, or model them as flexible switches on the same geometry. For flat-bottom rails, click the real > rails > head and foot (FB) menu option. You won't see any difference on the screen, but Templot will draw the printed templates with the rail foot edges showing. For early FB track it's likely that the check flares were bent rather than machined. You may want to change the rail section data at real > rails > rail section data... menu item. If I use one data set and then change my mind does Templot simply update everything based on the new choices, or do I need to re-model?I'm not too clear what you mean by "data set"? Everything in Templot is set individually to match your chosen prototype. Unless changed the defaults are always for REA bullhead track dating from about 1925. Once changed the settings remain in force* for subsequent adjustments to the control template but don't change any previously stored templates. However there are several "modify on rebuild" functions to make various aspects of the stored templates match the current control template. You will find these as modify group to match menu items. *if you mint a NEW control template, some settings are restored to the REA defaults. Last, the track plan I am following has a gradually tightening curve. How can I persuade Templot to do this?Click the geometry > transition curve > C-curve shrinking transition menu item. More about that at: http://templot.com/martweb/gs_geometry.htm#transition To fit a transition curve between existing templates you need the "make transition" functions. More about that here: http://templot.com/martweb/info_files/make_trans.htm and it is also covered in many of the videos. regards, Martin. |

There was a lot of Rhymney flat bottom track left at the grouping. Typically I've used loose heal 12' straight heel switches with regular V crossing. Modelling in P4 I've struggled to find suitable flat bottom rail. C&L used to do code 75 but really that was too big. |
