OO Curved Platform Distance Tool 3D print model

This tool is to help get the best distance between the train and the platform edge on a curved platform. 2nd, 3rd and 4th radius tool available.

At my local model railway club, we have a curved platform that has been redone several times because trains keep touching the platform so I thought I would work out the optimum distance 2nd, 3rd, and 4th radius track. To do this I looked at several items of rolling stock. To get this right I needed the length of the rolling stock, the width of the rolling stock, and the distance between the center of each bogie. I also looked at this in a very similar way for steam engines. Within the club, people said to use a mk3 coach, but after calculating the overhang mk3 coaches are not the best piece of rolling stock to use. Depending on bogie spacing some had a bigger external overhang but minimal internal overhand. The new class 800 IEP I wouldn't use on a track with a platform on a curve because to overhang exceeds all other rolling stock by a fair distance.

This tool is primarily a train bogie with two arms, one for the internal overhang and the other for the external overhang. I used two old plastic wheels so I could roll it around curved and Mark with a pencil.

Three tools can be printed for each radius of the tractrack. 2nd radius (438mm), 3rd radius (505mm) and 4th radius (572mm). Just print and add wheels and you're ready to mark where the platform edge should be.

The example in the pictures was printed on an AnyCubic Proton M3 3D resin printer. These items can be printed on a Resin or Filament printer.

The main resins I use for printing can be found with my affiliated links below. I use AnyCubic Water Washable Resin for most of my items but use AnyCubic ABS Like Resin for anything that needs to be stronger and tougher.
