Thank you fellows for your kind comments! 
Lee----> For me, write a magazine article would be very hard and very loooong because I don't have a full knowledge of your language; I don't speak fluently and I have always the dictionary beside me!!! if I would write, this would be for the second one because the way to build it will change and will be more fonctional and logical; this one is a prototype on which I look for better ideas and design. But I will speak about this new design soon in this thread.
Eric----> Pleasure to share; that's why I subscribed to this forum! here, the O scale is a very closed place and if you build US models or an US layout, not many people find an interest to follow you! that's also why I don't post on the french O scale forum anymore: it's a shame but to read some unpleasant and sarcastic comments make me angry and in this case, I answer nastily (french language is very rich in words!)

Scale C D----> I have the car but no layout; you have the layout but no the car! what to do? 
Bonjour de France
