Bonjour,
Please excuse that I'm writing in English, but my French reading is much better than my written one.
A definite case of cultural deficiency, I agree.
I live near Stuttgart in Germany and spend quite a bit of time in the Aquitaine every year.
This automatically led to an interest in the railroads in that general region. For instance, there was a CFD in the Lot-et-Garonne, which would be worth checking up.
What I also find fascinating is the large number of British and American rolling stock on French lines after WW I an II. This, in my opinion, is quite unique.
So there's a dream (so far) of building a small layout in 1:32 which shows the connection of a standard-gauge line to a sand pit or a mine. I'm busy collecting information (this website is a graet help) and checking for available material.
Amicalement,
Mario
