The 11 got scrapped by the Army, at Ft. Eustis, I think:http://cgi.ebay.com/Kentucky-Tennessee-RR-Locomotive-Photos-10-11_W0QQitemZ6554858363QQcategoryZ35975QQrdZ1QQcmdZViewItem

I believe that #11 was sold to the Army and used for target practice at Aberdeen before being scrapped there circa 1966. This was well into the preservation era and it is most regrettable example of "our tax dollars at work."
