Hello Marc,
These are some early steps of a bigger historic project based on foreign-inherited coaches used by SNCF after 1945. The first 4 are former German "Eilzugwagen" nicknamed as "Voiture Bastille" under SNCF ownership, due to being used on the Bastille line. My friend works on this project and there was a need for them, although the models reflect the coaches in the mid 1970s, when they were long-moved to southern France and used in regional service there until 1983. So... a little "Bastille" train supplemented by a former Pwi-29 coach is on the way to the download section...
