DSNG freight cars

This message has several questions in it. First is how many freight cars like box cars and flat cars does the DSNG still use? Is there any plans for like a small freight train with stocks cars, gondolas, and box cars? I read somewhere the group that is restoring DRGW 315 has aquirred a set of freight cars from the DSNG. Also is the DSNG having another freight car sale like they have had in the past. Finally does the DSNG have any plans for the dozens of freight cars in Sliverton and on differnt parts of the line. Sorry for so many questions, but just wanted to find out more on what I call the "forgotten freight cars" on the DSNG.
