GWR Chairs

[Stephen Freeman]

I have been busy in Freecad producing a range of chairs - still some way to go but here the initial results


SS Slide rail chair


rounded style of chair


00 chair - needs stretching yet

Squarer style of chair


Slab and Bracket ( I probably need to beef up the bolts a bit but not hard to do)

It is relatively easy to make at least some of the other chairs by combining STLS. The Slab & Bracket is made up of 3 STLs so possible to combine them in the required angle.


At the moment I have been concentrating on 7mm scale but of course the scale can be altered to suit other scales

I prepared a set of GW chairs but was unable to load them onto the resources section, possibly because the models were too large - iirc, I had ten chairs on a print raft, but it might have been more.

I drifted off the project (which was to complement Templot plug track) because @martin_wynne has taken Templot to the next level with chairs printed on the sleepers/timbers. Templot does not yet have GW chairs, and whilst it is now open source, I’m not at all sure that my programming capability is up to generating chairs in software (and with a full time job…)

I’m happy to share what I prepared, there are images in my workbench thread. They were modelled in Solidworks native SLDPRT but I’m sure can be shared as IGES or STP

the story and more pictures are here:

Very nice but needs a key and the securing screw, I won't call it a bolt because I'll probably get in trouble, there is no nut involved. As far as I know my slide and ordinary chair accommodate code 125 Hi Ni. I haven't printed the ordinary one yet but the slide chair fits. The way that Templot generates chairs involves programming, something I am trying to not get involved with as I had enough of that sort of thing in a past life.

Simon, very nice image.

I like that the chair does not include the key, your model allows for keys to be inserted left or inserted right, and by a different amount, as dictated by the usage of the individual prints. How about a separate print of the head of the chair screw thereby allowing for the "screw in chair" to be at random angles?

Scruff's Junction, using the S7 Group track standards, has much of the GW S&C chairs and fittings printed using an Anycubic printer with Siriya Fat Navy Grey resin, 3D CAD dwgs and STL files courtesy of another member of the S7 Group. Last count, the colliery tandem used approaching 30 different chair types/fittings.
