early screenshots page
(As it was during development on 24 January 1999. Templot has been extended since this page was written and now includes functions to draw a complete track plan on the screen in addition to the single templates shown here. Current screens and menus therefore differ, see recent screenshots.)
The first 7 screens are shown at the original 1024x768 size, so will have to be scrolled across on lower res screens. They were in 32-bit colour depth when they left Templot which the GIF file compression format may or may not reproduce well on your system. My screenshot software is clearly short of cheese, as it has completely failed to capture the mouse.
Then come 2 more shots from Templot running at 640x480 resolution in only basic colours.
Finally there are 2 scans of sample printed template pages.
1. The first screen shows a left-hand turnout in Gauge 0 Fine (GOG-F) with a GWR old-pattern 14ft heel switch and a crossing angle of 1:8. It has been curved onto a radius of 2205 mm, giving a minimum radius through the turnout road of 1371 mm (54"). This is more than the currently set limit of 1200 mm, so the warning lamp shows green. This screen view is called Templot's "drawing pad" and the "paper" currently has a background grid set to 1 inch spacings.
The information panel has been opened up to display all the details, and shows among other things that the pad zoom setting is locked at the current size, representing 657.14 mm across the width of the screen. I want to add a length of approach track at the left, so I have right-clicked to get the pop-up menu, and am about to click "zoom free" so that the pad will re-size itself automatically as I increase the length of the template with the mouse.
The grid spacing is 12 inches, and the bonded brickwork-pattern background shows the A4 page pattern for the printer. Only pages containing track would actually print, of course. I have shrunk the information panel out of the way, but by using its multiple scroll bars the essential information is still visible.
I have opened the gauge/scale selector form, and was just thinking of trying it in Gauge 1.
The grid is now showing in centimetres, and for some reason I have shifted the zero datum points for the pad view, and rotated the turnout to face left. For this turnout I entered a custom curved switch design, with a 1:4 curved crossing. Even for narrow gauge the curving is a bit severe! The TURNOUT menu is open and I am about to change to a right-hand version of the same turnout.
Unfortunately I have spoilt the whole thing by messing about with the pad drawing colours! So quickly on to the next ...
The ADJUST menu is open, showing the various mouse actions available, and I am just about to select ANY ANGLE for the crossing. This means that if I adjust the crossing angle with the mouse, the angle is infinitely variable. The 1/4 step alternative snaps the crossing to the nearest 1/4 unit angle, which is prototypically correct but sometimes a nuisance.
The quality of the printed output is determined only by your printer, the results are the same regardless of the screen resolution and processor speed. I have previously performed a PRINTER CALIBRATION for this printer, so there is no stroppy note on the print warning me that it might be dimensionally inaccurate. In fact, placing a steel rule on the print shows that the 1 inch grid squares are exactly true, and the track gauge is exactly 32 mm.
The final construction templates are normally printed on good quality plain paper (e.g. 100 gsm), but my inkjet is equally happy to print on ordinary tracing paper (or drafting film). So if I make a duplicate print on this, I can lay it over the rails during construction to check the alignment of the rails. (This is not an alternative to using the proper gauges, of course.) Bear in mind that a separate printer calibration for the tracing paper might be needed to get an exact match between the two prints. If your printer doesn't like tracing paper it's possible to use the more expensive coated OHP transparency sheets instead.
This is a "regular" crossing (i.e. the radius in the turnout road at the
crossing is the same as in the main road), and there is a short entry "straight"
to the crossing. The green line across between the rails marks the end of
the actual turnout curve. The red target mark in front of the vee shows the
actual intersection point (called the "fine-point" or FP) of the rail running
edges; Templot correctly draws the tip of the vee blunted off. Unless you
are modelling in an exact scale such as ScaleSeven it is usually better for
running to ignore this and use sharp vees, so the FP marker then indicates
where to locate the sharp tip.
Print on tracing paper, then spray the print with Spraymount adhesive (blue can) and lay the plywood timbers in position. Then turn the whole print over and prick through to mark the rivet centres. This saves the tedious business of marking them out, and gets the rivets exactly under the middle of the rail, which makes it a lot easier to fit cosmetic chairs later. The timbers can then be peeled off for punching or drilling, or using a mini-drill they could be drilled directly through the paper. You print a normal template for construction, of course, and having fixed the rivetted timbers in place on it, the tracing paper version can be used to check for any rivetting or timber alignment errors before adding the rails.
This is part of a B-7 turnout curved onto 1500 mm radius for P-87 (scale H0), this time with a "curved" crossing, so there is no green line - the turnout radius continues through the crossing.
For this print I changed the rail and timber outlines to thin black lines (1 inkdot wide, which the scanner has interpreted as grey). Templot lets you set the line thicknesses to suit your printer. For best-quality printing of the final templates thin lines obviously give greater precision; for quick trial prints in draft mode thicker lines are generally easier to see and work with. If you print at a reduced size, Templot adjusts your line thickness settings accordingly.
The prototype rail joints are marked, showing where to add dummy fishplates. (This is not necessarily the best place for any 2-rail insulation gaps, which are not part of the prototype and therefore beyond the scope of Templot - you might for example be using live steam, clockwork-drive or batteries, or modelling trams.
