Many of us have probably used the Airfix/Dapol girder bridge, but I am wondering what the track should look like. It dos not look eight just laying a piece of sleepered track.
I have had a look through Google images but can not find anything that makes it clearer.
I prefer some form of solid base to the track, and am thinking about 3D printing based on my tram track designs. Turntable track is another option as I am most of the way there with my tram track inserts and panels.
Any comment ?

The common way of attaching track to a girder bridge is on waybeams resembling longitudinal sleepers but normal cross ties can be used if the ballast is contained in troughs. Coffee stirrers could be used to represent the woodwork retaining the ballast or rocket sticks for the waybeams. No ballast is required with waybeams because they are bolted to the steelwork.

Bob, that was what I thought, not easy to design for 3D printing. Finding an easy way to hold the rail is the key. I was hoping to find something like the metal infill as on the Wills bridge kit, which is something I will do anyway.

I have taken the bull by its horns and using the end profiles from my tram track have designed something to replicate the longitudinal beams, into which code 100 rail can be slotted into. First example is being test printed at the moment, hopefully.
If it works I should have parts to build lightweight girder bridges, and also fitting rail to girder bridges like the Dapol/Airfix one.

first samples received today, just some minor mods to do, which I think I included on newer versions anyway.

Latest version of lightweight bridge. As the price seems to be a lot higher for 16.5mm gauge, it made sense to add as much detail as possible. Not cheep but possibly still worth it.


Takes code 100 rail. Hopefully I have modified it enough to make job of fitting the rail easier. I forgot to include gaps under rail space on first sample, and it was difficult to force rail through. I had a similar problem with the tram track initially.

Got into doing suirly type things, so added some fancy railing to bridge


also a spiral staircase in various scales . This version in 1/24, but also(with slightly different step detail on each) in 1/35 and 1/76

Just making some bridge parts available. One of the neatest I think are clip on rail bases for Airfix/Dapol girder bridge. Looks a lot better than sleepered track on the girder bridge.
