When I'm not frying my brain trying to model Irish Railways in OO or American railroads in N, I'm concentrating on modern day SNCF in HO scale. In all honesty, it probably has greater priority than the other two areas for me right now.
My plan is to eventually build a layout loosely based on Langogne station, on the famous Cévenol route between Clermont-Ferrand and Nîmes (photos here). It's a lightly used trunk route that's seen better days and, although the stock is modern and the scenery is fantastic, the infrastructure looks rather dilapidated, and there's still semaphore signalling and hand-operated points in places. Added to that, the freight and track maintenance trains are magnets for graffiti artists (see photo link).
Here's a rough trackplan of Langogne that I cobbled together:
My layout will be a somewhat simplified version of this. For one, the yard will be smaller and there will only be one engine shed and water tower, and possibly no turntable. I also want to fit in some features found at other stations along the line.
As for stock, passenger services will be handled by X73500 and AGC diesel railcars, and loco-hauled Corail coaches hauled by the venerable BB67400 diesels - all operated by TER (regional railway division) of the Auvergne and Languedoc-Rousillon regions. As for freight, the only flow currently transported over the line is timber and pulpwood, handled by a pair of EuroCargoRail MaK/Vossloh G1206 locos. Maintenance trains are handled either by the long-lived BB63000 or BB66000 locos, or by privately-owned contractor locos. Light shunting is undertaken by Y7100 'locotracteurs'.
Here's some of the stock that I'll be running:
X73500 in TER Auvergne livery...
Y7100 locotracteur in Arzens livery...
Inox coaches (to be heavily weathered and graffiti'ed and used as dormer/workshop coaches on works trains)...
