Hi everybody,

I don't know if it is the right place but I've developped some French railways products on 7mm scale.

Hi everybody,

I'm back...

😉😉😉

I've bought this layout but currently I'm building a new 7mm scale layout with the similar trackplan.

I've built tracks and pointworks with some 3D items from FAB432. Cf. https://www.shapeways.com/shops/fab432

FAB432 is my new cottage industry.

I've designed a manual pointwork control (lasercut).

And I've designed some typical buildings like the signal box of Longroy Gamaches (Somme/Seine-Maritime), a 6 meters Saxby signal box, the goodshed of Miraumont (Somme) and the foot bridge of Amiens (Somme) station.

Saxby signal box from the start (kit) to the end

To be continued...

Best regards from France, Fabrice

David,

It sounds great...

And I like your graphic

Hi all of you,

All the best for 2020

Thanks for your sharing

Very nice layout

Hi all of you,

I've modified the Tokenless Block System program. I've added some comments to improve the understanding.

Hi all of you,

In progress with some new products of Cites Miniatures (railing and hollow brick wall)

Have a G'day, Fabrice

Hi all of you,

Happy new year from France

So, I've finished some detail parts on the bed track.

And currently, I've building a CdZ (the French Gauge O Guild) U-60 kit.

To be continued...

Very nice weathering, Duncan

Interesting method

Good job...

Well done...

Could I take a ticket to ride, please?

Hi,

Nice signal box

Do you add a part of station building too?

Fabrice

November 5, 2018

Thanks Ernie for your comments

Currently, I would like to know if my baseboard design is enough strong.

Fabrice

No more comment, remark, suggestion, proposal?

Hi all of you,

I've modified the trackplan.

I've finished the baseboard design (2 sheets of 5mm plywood).

What do you think abour this design? is it enough strong?

I'm waiting for turnout kits to verify the baseboard design.

Nice trackplan

I like your fiddle yard system.

Fabrice

October 23, 2018

Hi all of you,

Trackplan : Approved

I've designed the baseboard (half part of).

I apologize for French comments.

What do you think about it?

Fabrice

October 18, 2018

Marc

That's the good question. I don't know.

Currently, I'm drawing the baseboard

Thank you...

Marc,

I will be a betatester for these new products: https://www.shapeways.com/shops/la-voie-du-zero-1

Martyn,

Good proposal but I would like to minimize the number of track to preserve scenery. The first pointwork on the left is a tandem turnout.
