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 Some of the earlier pages of this topic are now out-of-date.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.

Presumably lots of folks knew this was coming, but it's a surprise to me:

Although not a complete surprise -- Templot has been ready for years: :)

I have removed the USA/Europe branding in 234d.

cheers,

Martin.

I must admit to being a little bemused by this, and I've already seen confusion between this scale and 3mm:ft on social media. Is there any British outline stock to go with the buildings in 120th scale? Apart from a single wagon, that is. I don't really get why Peco didn't use the established 3mm:ft scale for this project - I could even understand them still using 12mm gauge track, but this? It doesn't make sense to me.

This has also reminded me not to sit and wait for a subscription copy to drop through my letterbox - I'd be waiting a long time!

Makes sense to me, even though I model 3mm. Doing 3mm would have been messy; e.g. which gauge do they go for? Here they can adopt one set of consistent standards, which will yield benefits in years to come. It will also encourage other manufacturers to come on board. It shares the advantages of a 3mm sort of scale without the disadvantages. I've been hoping for years that somebody will seize the bull by the horns and Peco have done it.

Looks as though they've gone for the finescale end of the market.

I doubt Peco would have made such a substantial investment in tooling if they didn't know something is in the pipeline.

To me it doesn't look much of a jump from British N gauge (1:148) to really fill the gap between 4mm. It's more of a jump from USA/Euro N Gauge (1:160).

Also using an exact-scale track gauge (11.96mm to be exact) with RTR wheels means models will have the same over-width errors as H0 to fit a clearance and sideplay over the wheel faces. No doubt the target market won't be much bothered about that, and be more swayed by the "exact-gauge" tag -- just like H0.

Who really wants to work at 2.54mm/ft? Maybe 100 thou per ft will be handy.

There is public talk of bringing back imperial British measurements -- Peco could have gone for 1:128 (3/32"/ft) and stamped "Made in England" all over it! I think I will add HS gauge to the list just for devilment (Half-S). :)

Martin.

I suspect both track and wheels will be fairly fine, as in 3mm Soc fine standards.
