TEMPLOT 3D PLUG TRACK - To get up to speed with this experimental project click here.   To watch an introductory video click here.   See the User Guide at Bexhill West.

  • 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 Some of the earlier pages of this topic are now out-of-date.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 topic.   For some practical modelling aspects of using Plug Track see Building 3D 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.

Use of rail anchors to prevent rail-creep

Rail anchors are hammered onto the rail foot and bear against the side of the sleepers (ties) to prevent the rail from creeping through the fixings.

Rail-creep is caused by the rolling-wave effect from the wheels. The rail is pushed forward in the direction of travel. Except on steep gradients, where gravity causes the rail to creep downhill.

It is important to prevent rail-creep because it can cause expansion gaps at rail joints to close up. Which can cause the track to buckle in hot weather.

The link shows a photo of rail anchors in use on USA spiked flat-bottom track.

When used on bullhead track, the rail anchors bear against the side of the chairs.
