My guess is these guns were in battery and that the narrow-gauge railway brought the munitions up to the battery, where they were off-loaded with the crane to field-constructed lines for the ammunition dollies. The website doesn't list pricing for everything, so I wonder what it would set me back for the gun, the limber/etc. and the train? Could be a smashing diorama worthy of Alan's stuff.

Which items is it that doesn't have a price listed ? / Robin I just scrolled further down into that pdf-file I linked to in an earlier post and found this: "La voie étroite sert par ailleurs à la construction et à l’installation des plates-formes d’artillerie lourde. Le mortier de 370 mm Fillioux, par exemple, est transporté par voie de 0,60 m et mis en place avec un pont spécial monté sur des bogies Péchot. L’emplacement choisi pour le tir est ceinturé par un quadrilatère de rails reliés par des plaques tournantes à galets. Un des bogies portant le pont sous lequel est suspendue la pièce (29 tonnes) fait son entrée sur un côté du quadrilatère en tournant sur une première plaque, puis fait de même sur le côté suivant grâce à une seconde plaque ; le pont effectue en même temps une rotation sur les plateaux pivotants des bogies Péchot jusqu’à sa position finale, perpendiculaire à la voie d’accès. Après avoir déposé la pièce sur l’affût, il est retiré par la manoeuvre inverse. Les rails permettent ensuite l’acheminement des obus sur des wagonnets spéciaux." It is about installing heavy artillery, in this case a 370 mm mortar (Fillioux). The rails were used when lifting the heavy stuff in place, gantry "crane" on rails and later the rails were used to bring the shells to the mortar with special wagons.

Thanks Robin. So the pictured tracks should be 60cm narrow-gauge tracks indeed. One of the "wagonnets spéciaux" used to carry the ammo to the mortar is visible in my previous post (it's not included in Blitz new release). H.P.

There is a first time for everything and this is the first time I ever managed to find information that H.P. hadn't found already Happy Easter / Robin

Well done Robin ! In fact I have downloaded this PDF document some time ago but I must admit I haven't thoroughly read it...even though it's in French Glad Påsk ! H.P.

I did not find pricing for the rail lines, but it may be I did not look on their site sufficiently. I will recheck since you're sure.

If you go to this series (which is excellent in any case) and start at 29:16, you can see how these narrow-gauge tracks were used to bring large shells up to their guns.

I agree, Robin. Thanks for sorting that out. Should be an awesome build.
