Alongside my WW1 project in 1/35, I wanted to build something in metre gauge. I initially designed and had 3D printed a Corpet Louvre loco in 1/32 running on an old Rivarossi O gauge chassis I found. This looked very nice but I knew I coulkd not afford to get some French railcars built so looked at smaller scales.
Initially I thought S scale 1/64 on 16.5mm gauge but had trouble finding suitable chassis and could not find French vehicles in 1/64. I bought some diecast cars advertised as 1/64, but they looked too big and found other shops advertising them as 1/54, so thought why not model in 1/5 (5.5mm foot) and still use 16.5mm track. Strictly speaking EM gauge would be closer but I wanted to use low cost(?) chassis etc. I will use the 1/64 body somehow.
So upped the design from 1/64 to 1/.55, and found the Bachmann USRA 060 loco was a very close fit. I had found this chassis perfect for my 1/35 Decauviulle and Joffre, so knew where to put the fitting points.
Loco was sent off for 3D printing and I fitted the chassis yesterday. A couple of small changes to the body, so if I get another 3D print it will fit first time.
A quick coat of black matchpots emulsion and I had the loco shown here.


This is one of my favourite French metre gauge locos, and I have an LGB one, so thee was no real alternative for me. I will look at the other very similar Fench loco found on many lines, but next model will be a railcar, probably start with easier post war one then one of the pre war ones with all those curves. Considering one of the Renault ABJs but they are huge even in this scale.

An interesting choice of scale, Simon, and one that looks like it will pay off. Which railcar do you have in mind? Off the top of my head I'd guess a Billard A80D might fit on top of an HO American switcher chassis.

I recall the old GEM Festiniog kits, but those were, of course, 2ft gauge prototypes and so ran on 12mm gauge track. I guess metre gauge models will look a bit more bulky. Do you have a potential layout design yet?

I suppose the idea goes back to when GEM were still exhibiting at Manchester Model Railway exhibition, and they told me they had planned to produce 3ft gauge models to run on 15.5mm gauge, but the idea was dropped when the scale was dropped.
It was just a happy coincidence that scale and gauge were close enough and discovering some vehicles in that scale. Ironically I had the Lledo Citroen H van and did not realise it 1/54 scale.
There is also wonderful symmetry in the scale, 1/55 being 5.5mm / foot.
I always liked your French layout Giles, but 12mm gauge is not a low cost gauge to work in these days. It was easier creating my Corpet though, than converting a GWR loco, as I think you did.
As for a railcar, I have drawings for the post war 150D, but really want to get my hands on an A80D. The wheels are pretty small on these railcars in this scale, so might end up using a Tenshodo or Black Beetle unit. The big Renault probable could be powered by an old Lima unit. Lots to do.
Not sure how 3D printed railcars will come out. Someone has done them in Nm, so should be OK. Won't be cheap, especially as I may pay extra for better quality plastic.
The only downside for me is that small scales like this can't make use of my low cost molded mashed paper buildings as I can't get detail small enough.

I think I know the Citroen model you mean, Simon. I always thought it was about 1/43rd scale, but never checked. A 7mm or 1/4inch scale French layout is something I've thought about (having two French magazines with conversion articles) but it would be a lot of work, and Magic Train models are getting rather pricy to chop up nowadays,

On the matter of small enough wheels, what about a Bachmann bogie trolley car in HO? They certainly provide a low-slung chassis. If you would like dimensions I have one I could measure.

Best way to check vehicle scale is wheelbase, found on Wiki. I knew they ere not 1/43 as I had several in that scale at one time.

For a motor bogie the wheels on the trams are small enough, but wheelbase too short. Also by the time I have found a suitable motor it is just as cheap(?) to use a Tenshodo unit. I didn't want to have to do as much work as the motorization in Voie Libre using a stretch N gauge unit. I am confining my 12mm gauge modelling to a small miniature line in 1/32 scale.
The units used by Bachmann under their Trackster rail mounted road vehicle might be a possibility. The bus is very good, but too big. ill ned to have a look at one of the other units.

What about a Renault Scemia type of railcar (think that's how it's spelled). Nice square body with straight tapered ends. Not common but they were to be found, including on the Cambresis system, which is what I based a model on a while ago.

Deciding on model mainly because of its ease of designing is not way I normally work. I would like to have one of the pre-war designs with curved ends as they were so common. Having trouble getting windows to look right, so project on back boiler for the moment.
Too many distractions, but once I am happy with my tramway track panels, might get back to railcars. Mind you I have now found that Decauville 8 ton loco will probably fit on Roco TT chassis so that is a third gauge introduced to the project.
