Hi again, firstly I suggest you head over to http://en.wikipedia.org/wiki/Special:Userlogin and signup for a user account so all you contributions get tied to you. Also, for the references section of Rail transport in Morocco it would be nice if you can add the titles of the books and websites you are using, even if they are not in English. And finally, I assume you live in Morocco - if you were able to take photos of any remaining lines, or locomotives in museums and upload them here it would be really good.
