NEXT ZOOM MEETING - All welcome - The next Templot Club Zoom meeting is on Wednesday 29th March 2023 at 8pm UK time (20:00 BST - 19:00 UTC). How to take part: click here.

TEMPLOT 3D PLUG TRACK - To get up to speed with this project click here.

  • The Plug Track functions are experimental and still being developed. Some of the earlier pages of this topic are now out-of-date.

    For an updated overview of this project see this post.   For some practical modelling aspects of using Plug Track see The Book of Plug Track.

    The assumption is that you have your own machines on which to experiment, or helpful friends with machines. Please do not send Templot files to commercial laser cutting or 3D printing firms while this project is still experimental, because the results are unpredictable and possibly wasteful.

    Some pages of this and other topics include contributions from members who are creating and posting their own CAD designs for 3D printing and laser-cutting. Do not confuse them with Templot's own exported CAD files. All files derived from Templot are © Martin Wynne.

Sometimes where we have tracks crossing on multiple levels a means is needed to indicate which track is on which level.

For tunnels, hidden sidings, etc., it is easy enough. The hidden tracks can have the timbers omitted, or be shown in marker colours.

Where tracks cross on a rail-over-rail overbridge it is not so simple. The lower level tracks may include pointwork for which we need to see the timbering, and the section below the bridge is likely to be shorter than a full template, so that changing the template marker colour wouldn't help.

Ian Allen mentioned this issue recently.

Hi Ian,

For such situations I suggest adding parapets to the upper tracks, which provide a visual indication of an overbridge:


Solid parapets may be purely symbolic of course, if the actual bridge will have railings or the tracks run between side girders.

The parapets function is a simple kludge using modified platforms, see:

The position and length of the parapets can be adjusted in the same way as the platforms.

On the printed templates parapets appear with solid infill, but on the trackpad view they are outlines only -- I will look at adding a hatched infill to make them more prominent.
