This is a track inspection tool designed to find bumps & hollows. It comprises a flexible strip that can be placed on a rail, with three guides to help the placement.
On a bump there will be gaps visible at each end of the tool/rail boundary & the tool can rock on the bump.
On a hollow there will be a gap visible in the middle of the tool/rail boundary.
This is a variant body for the 16T Mineral Wagon - Clip-together created by Tref Waldorf. I have use the Prusa sliccer to emboss the sides with G 1 M R A & also a panel that reads "Return to Surrey Oval". I have posted the .3mf file so you can use the Prusa slicer to edit the words if you wish to change the return destination.
My Merlin!
Mostly to 10mm scale. Printed on an Elegoo Neptune 3 Pro, with PLA plus filament. Two N-20 motors power the drivers, controlled from the tender by batteries and a small DC motor controller.
This is openSCAD code that can be used to generate a variety of various railway wheels.
Included are some images and sample wheel stls. All the samples are 1/32 fine scale renders. All have been rendered for fine details ($fn=200) other than the Mansell wheel which was rendered with $fn=100 to keep the size of the stl reasonable.
The code can also produce standard wheels in both 1/32 and 10mm scales. Also supported are 3.5in and O gauge by selected the correct "sf" value in the code. The code could be extended to support other scales.
Commercial point levers of the 'lever in diagonal slot' pattern can be self built with various throws as required.
These printed versions (once designed) offer a faster to make alternative and avoid the separate lever rod that often becomes detached in commercial offerings.
Three alternative throws (2mm, 4mm and 8mm) are provided. Others may be added later as reqd. Commercial levers are often 6mm throw.

A version of the ubiquitous 16T Mineral Wagon designed to be easy and fast to print and assemble. Almost as easy to disassemble, in order to replace any parts. Can be run with the wheels and axles as they are, or fitted with R144ZZ Bearings at any stage, without any further parts required.
Both Coarse and Fine G1MRA standard wheels and axles included.
Proven out on a Prusa Mk3 i3, in PETG
Here I have enlarged my 08 shunter to Gauge 3, 2.5-inch gauge. I did this some time ago, now final finishing a few things and tidying up the files.
To save space I've added zip file.

This hook has been added following recent requests for a 3d printable one.
Some hooks are contained within various wagon models but this one was designed to replace a Northern Finescale plastic moulded hook.
No doubt laser cut steel hooks are much stronger but this hook when printed in PETG has been found strong enough for most applications.
The examples shown are printed in silver PETG (I would normally use black). Infill was 100%, layer height 0.1mm, a brim was included to aid bed adhesion.
A set of detail parts created by myself to spruce up the Model Engineer's Laser Tram loco kit (see related content)
My take on a SR milk tank wagon at 10mm scale.
Spacers to help lay double track.
Designed for Cliff Barker track, gauge widened (45.5 mm gauge)
These were designed for Cliff Barker track. There are two versions, 8mm wide and 9.4mm wide, and they give 1,2,3 or 4 mm superelevation. Best to glue or solvent weld them onto the sleeper bases - every three or four sleepers is fine.
This is the model for a SECR-designed and SECR/SR-built van to Diagram 1426. Several of these vans were rebuilt with ventilated sides for use on London-Dover-Folkestone fruit traffic, subsequently labelled as Diagram 1427. This van survived into BR revenue-earning service, and several becoming departmental vans in the black livery.
There were both unfitted and vacuum fitted versions, and a brake cylinder has been provided for the latter. You will need to source vacuum pipes yourself, however!
Please note a few caveats:
This is a model of the early Stockton and Darlington railway Chaldron wagon. It is based on the images of a wagon in the The National Railway Museum at Shildon catalogue number: 1979-7005
Simple wagon wheels to G1MRA Fine and Standard profiles
The bore is sized for 2.9mm for reaming 3mm or 1/8" as appropriate. I have used this with success on 3mm ground steel axles into 3x8x3mm ball-race bearings.
I have included a 40mm B2B Gauge, a 42mm B2B is available on the G1MRA 75th Anniversary Brake Van model.
This describes my 10mm version of Peter Davis' brilliant model, including my construction notes and STL files for the new parts made. This is now a revised version with additional new parts.
Enlarged version of my G1 Sentinel.
The largest piece is the body at 224.1mm long. My Elegoo Neptune pro printer has a table that will accommodate this.

9/Feb/24 Updated: G3-22.0 Handrail 1.stl Shortening height form 5mm to 3mm.
The parts are called 'Active' because that was the locomotives original name. Michael Bailey's report is here: https://www.railwaymuseum.org.uk/sites/default/files/2023-10/Pages%20from%20LOCOMOTION%20report%20part%201.pdf
The files contained here are experimental and have been made available for development purposes only. There is not yet sufficient to make a complete locomotive.
This is still in development - if you find a problem or have suggestions for improvement please send feedback.
The initial inspiration was to create a representation of a coal load or ballast track bed.
The code is capable of generating a simulation of a full coal load, part used coal load or wagon fill, coal pile, flat spread/ballast, straight track base, radius track base.
The track bases can be used to merge with track models before printing or can have a slot cut for using loose track.
Here is some openSCAD code that can be used to create handrails and stanchions.
The code is still underdevelopment.
To use you can either create and 3d model for a single stanchion or the code can be used to create a single modle multiple stanchions and handrails.
Currently limited to a single style of stanchion and cylindrical handrails.
The first image shows what is generated by the default openSCAD code.
No STLs are currently provided as these would depend on usage.

22/Feb/24 I found Flats should be filed on the Jack Shaft and the Axle Shafts where the Sprocket set screws seat.
A small collet chuck for 1mm, 1.5mm, and 2mm drill bits that makes it just a little easier to "twizzle" the bit between the fingers.
Many G1 modellers who have their own rolling stock use the 'Really Useful' brand of plastic boxes, particularly the 22l version for transporting and storing G1 coaches.
A problem with these boxes is that if stacked and then slid over one another the standard blue polypropylene lid clips can come dislodged. If one is not careful one can find that trying to lift 2 boxes just results in lifting one and a lid.
The object of this clip design is to provide a more secure clip that does not project above the box top and prevents dislodging.
Tref’s G1MRA Anniversary Brake Van Project was a van to celebrate the 75th Anniversary of G1MRA, with a contribution from the 3d Printing Circle.
It is intended to be easily printed and assembled on the majority of FDM printers.
The initial publication of this coach is an attempt to make a simple model for the "Christmas tree" project.
Some discussion is needed to simplify the design to make it easy to print. Currently the break gear on the ends of the coach are rather fragile and the body, if printed on a resin printer probably needs dividing into two for most printers.
The smaller components were designed for resin printing. The body, when resin printer is in two parts.
